I have owned both this and the original version. The new lens is better in the corners and flares less but the corners are still a little soft at f2.8 and you can get the lens to flare a little if you try. I haven't seen the loss of clarity above 20mm that others reported. Perhaps you would see a slight difference in eyelashes if you did a lot of portraits but this is probably not the best choice for a portrait lens. It is a somewhat better lens for shooting landscapes and other shots where edge to edge clarity is important.

But the differences between the two versions are minor and in some instances irrelevant. If you don't shoot a full frame camera the soft edges don't appear in the photo. And flare is a minimal issue at most. It rarely appears and is easy to fix in Photoshop if it does. I would opt for the original if I didn't shoot full frame based on the price difference alone.

My only problem with the original was when I had to shoot hand held. Sometimes you can't bring a tripod along which rules out shooting at f16 or 22 so I occasionally ended up with shots that were soft in some of the edges. The new lens will solve that. That is the only reason I decided to upgrade.

I haven't used many other lenses in the same range so I can't compare quality with other makers but I'm not aware of anything reputed to be better. I have Canon primes as well as other Canon zooms and in actual use all are generally close in quality. I use the primes if possible when I plan to crop or enlarge a lot but I could still get by nicely with the zooms.

So, if you shoot less than full frame or if price is an issue, get the original. If you shoot full frame but need maximum clarity in the center (portraits for example), test both versions first. If you shoot full frame and need maximum edge to edge clarity, go with the new lens.

Update: Having shot this lens for a long period I would discount the comments about problems above 20mm. I owned the first version as well and I don't see a difference in the 20mm to 35mm range. On the contrary, I am increasingly impressed with the image quality and sharpness of this lens throughout the range. I recently used it into a very narrow slot canyon where I couldn't take more than the camera and the lens attached to it and took shots from 16mm up to 35mm that all came out very sharp and rich. Granted I wasn't shooting wide open because I needed lots of depth of field but the point is the lens delivered the best shots of that trip. In terms of versatility, this lens is unmatched for wide angle use by Canon owners. I also have the 14mm f2.8 II, 17mm f4. TS/E and 15mm fisheye for comparison. This is the one wide angle lens I always take along.

Canon EF 24-70mm vs. 24-105mm IS: Read this if you are a hobbyist

Canon EF 24-70mm vs. 24-105mm

I am a hobbyist and this review is for people like me. What I mean by that is that I take pictures for fun and nobody buys my pictures. I mostly shoot landscape, nature, and portraits of family, friends, and relatives. I will refer to 24-70mm as the 70, and the 24-105mm IS as the 105. I first made the mistake of buying the 70, then I returned it with a hefty restocking fee and bought the 105 - I don't have the slightest regret and I could not be happier.

I'm taking my time to write this review so that you can spend your hard earned money wisely. Let's analyze the trade-off between the two:
* Both lenses have excellent build and image quality. So these are not differentiating factors.
* The one and only advantage of the 70 is the one smaller f-stop. For me, this means more blur when I shoot portraits, so this is all good.
* The advantage of 105 over the 70 are as follows:
- You get an extra 35mm, which is 50% more zoom. I like this.
- You get a 3-stop IS. For me, this is a great advantage, because I rarely use tripods and IS saves the day. I would choose the 105 over 70 for the IS alone.
- The 105 is 10 ounces lighter and close to half an inch shorter.

The last part is the most important part: that additional 10 ounces make a heavy lens TOO HEAVY, and that extra length makes a big lens TOO BIG. Carrying the 70 on my 50D was a pain. I can assure you, the 70 is just too heavy to walk around and take pictures for fun. The keyword here is "fun". The 70 is a pain, the 105 is fun. The 105 is still heavy, but not too heavy. It's still big, but not too big. After having the 70 for a few weeks, I lost all my joy for shooting. It just made me very uncomfortable (and I'm 6-foot 2). When I replaced it with the 105, it did make a difference. I enjoy taking pictures now, once again. Pros might like the 70 because they need it for their professional work. But if you're shooting just for fun, stay away from the 70 and get the 105.

Sigma 70-300mm lens of Canon SLR Cameras

I hesitated purchasing this lens for my Nikon D40X--probably looked at this listing six or seven times before making the purchase. Truthfully I was worried about how inexpensive it is. Now, I'm probably a pretty average amateur photographer in that the majority of my pictures are family stuff: kids' sporting events, vacations, birthdays, and the like. But that doesn't mean I'm willing to compromise on quality just to save some money, and I know that the Nikon 55-200 is a quality lens.

But, I purchased based on Michael Del Priore's review (his was the only review at the time)--I figured, at this price (especially when compared to the Nikon 55-200), why not give it a shot, and I'm glad I did.

This is an excellent lens. The auto focus motor is fast and doesn't chew up the battery (I was concerned about that, but I shot almost 170 pictures at my son's games two Saturdays ago and didn't use any more battery than the Nikon 35-70 lens that came with the camera). Like "cinderoo" I haven't had any stabilization issues to speak of either, even snapping away while following 12 year old boys run the length of a field. That may be more of an issue with macro photography, but I'd imagine most of the (admittedly limited) macro photography I'd do would probably be with a tripod anyway.

Now, no one would mistake me for a professional photographer, but I can tell you that when I pull up photos shot with my D40X and this Sigma lens on my 24" iMac and view them full screen they are *everything* I was looking for when I decided to move to an SLR camera.

Wow! My theory now is that Canon doesn't put this baby as their kit lens because many people would decide that they DONT NEED ANOTHER ONE! And many of them would be right!

Like others, I bought the Rebel XT and the 28-135 IS lens. The 28-135 is heavy and priced like a gold brick. I guess it does OK, and I do keep it mounted most of the time.

And like others, I stumbled on this lens somehow, read the raving reviews, and for the price figured, "What the heck?"

This lens in tack sharp. It shows the fire in the colors you photograph. The wide aperture means candles can be excellent lights for portraits. Its narrow field is great.

There are pitfalls though. I snapped a pic of my face at arm's length using autofocus a while back and (1) the focus locked on the tip of my nose and my face was already blurring (2) the lens was so sharp that I saw blackheads clearly on my nose tip I can't really see in the mirror (doh!). I've read that dSLR images are slightly soft to aid in later editing. I can only imagine what it would do on a film camera.

Yesterday while camping I slapped this lens on. Unlike the 28-135, this one is light enough that I didnt notice I was carrying a camera everywhere. At night I put the lens on the top of the car pointed at the sky, set the shutter for 15 secs, and hit the button. Much to my amazement, the lens not only showed hundreds of stars that were invisible to my eyes, but it also found a galaxy. That pic is on the customer image section of this page. You can see what I saw, but the smaller size doesnt do the lens justice.

One quirk of Amazon is that this page keeps alternating pictures of lenses. This lens does not have the distance focus scales on the outside of it.

Zoom is nice for many things. But where zoom isnt necessary, performance is very, very nice. Performance at $70 is almost too good to be true.

Let me close by repeating what has been said elsewhere and will continue to be said here....IF YOU OWN A SLR, STOP NOW AND GET THIS LENS!

UPDATE 12/06 I have owned this lens for about a year now. Over that time I have immersed myself in photography, workshops, books, tests, etc. I have since upgraded to the 30D and a couple of L lenses, and now have a portfolio strong enough that I am now getting dollar signs thrown at me that I didnt even see coming. I say all this to give you some perspective on what I will write afterward.

Now that Ive really learned the difference, I can agree with others that it is a tad soft wide open, but that is to be expected. I read a lens test recently that put the 1.8 against Canons heavweight L glass, and, not surprisingly, the L beat out the $70 plastic wonder in most categories. What might surprise you, however, is that when the lens was tested at F 8 it BEAT THE L GLASS in sharpness! As one that has felt the pain of trading large sums of money for L glass, I appreciate affordable quality...not something anyone can plan on seeing much of in photography.

My 28-135 has since joined my kit lens in the garage. The 1.8 is still in my case with my newer 30D.

With some experience under my belt I now would make the following recommendation. Right now, as you read this, you may have an idea if you've been bitten by the photog bug. You may know that this beast is going to morph into something more than a simple pasttime. If you look inside the depths of your aspirations and you know that you are going to be a serious amateur, bite the bullet and get the 50mm 1.4. Trust me on this one. Eventually you'll end up getting it anyway, so just apply the $70 to the 1.4 now.

If you're just exploring different areas of SLR photography, you cant go wrong with this lens. Case in point- as of this writing the baby in pink in the customer images section of this lens is one of the top-ten rated images of all pics uploaded on Amazon! This lens will allow you to dazzle friends and relatives used to snapshots from point & shoots. It will be the start of what you upgraded to a DSLR for in the first place. For you, the 1.8 is still, by far, the best value in photography!

All I bought at the price $100.45  dollars from website amazon.

 Canon EF-S 55-250mm Lens

Since I mostly use wide-angle lenses, I was not willing to blow a ton on expensive/heavy telephoto lenses for occasional shots. Prior to owning this lens, I had a Sigma 70-300 APO zoom telephoto that produced good colors, but was essentially useless due to frequent camera shake. I sold the lens and got this Canon zoom.

a) Surprisingly, it CAN produce pretty sharp pictures if the subjects don't move fast. The sharpness is very comparable with two other lenses I own, the famed and breathtakingly sharp Tamron 17-50mm f/2.8 and Sigma 30mm f/1.4. While the Tamron and Sigma get sharp shots without too much work, this Canon needs a bit of careful handling to get equally sharp shots even at the wide end. I use the word "can", because to achieve it you would either need a tripod or high ISO (my rebel XT's 1600 is pretty much what I use all the time with this lens).

b) The colors in bright light are almost always faded (sharp, but faded). It can be patially corrected in Lightroom, but a bit unfortunate since this lens really needs the bright light for a good shutter speed. Indoors, it produces good color balance/saturation, but struggles to have a decent shutter speed. Kind of catch-22 situation.

c) The construction is pretty cheap, but generally nothing to worry about if handled gently. However, the filter threads are thin plastic and I almost damaged the threads when putting on filters for the first time. I got a dedicated Sigma DG 58mm UV filter permanently affixed on it so that any other filters/screw hood will only go on the metal thread of the UV filter and not the lens thread directly. A metal UV filter is a must if you don't want to permanently damage the lens filter threads.

d) The opteration of the IS is quiet unless you are particularly listening to it. My Tamron's AF makes more noise.

e) After playing with this lens for sometime, I have come to the conclusion that IS is an absolute must on a zoom telephoto when hand held. Being the cheapest IS telephoto on the market today, there is really no equivalent for this in this price range.

f) IS has been of no use in freezing subject motion. While this is to be expected, it highlights how slow a lens this really is.

g) No hood comes with the lens, but I got a third party 77mm screw telephoto metal hood and step up adapter rings.

h) 1 year canon warranty sucks big time compared to the 6-year Tamron and 4-year Sigma (for DG lens).

i) this is a very light lens, much lighter than my sigma or tamron. Very easily carried around (hood might add a bit more bulk, but not too much).

In short, this lens performs great with regards to sharpness and IS. It leaves a lot to be desired in color saturation and flare control, almost always requiring some kind of post processing to achieve desired result.

The best Lens for 1.6x Crop Canon DSLRs

Canon EF-S 17-55mm f/2.8 IS USM Lens for Canon DSLR Cameras

 Lens for 1.6x Crop Canon DSLR

I received my Canon EF-S 17-55mm f/2.8 IS USM lens today (12/28/06). It feels heavier by far than the 18-55mm kit lens, but lighter than I expected. Feels good (well-balanced) cradling the lens in the left hand near the base of the lens when mounted to my Canon Digital Rebel XT. I put the lens on the camera right away in a manner that would limit the opportunity for dust to intrude on the back of the lens or into the camera, since I've read about this lens not being sealed as well as "L" series Canon lenses. I may never take it off. 8-)

This lens focuses fast and sure--even in low light, no hunting around to lock onto a subject. Pictures taken with the camera hand-held at 1/10 to 1/15 sec shutter speeds inside with no flash were tack-sharp (Thanks to the IS). With F2.8 and IS, this lens opens up a whole new world of natural low-light photography. Not only are more inside shots possible, you also have the versatility to create gorgeous bokeh. You create these bokeh effects generally zoomed to 55mm (where the kit lens' max aperture is F5.6). Since the EF-S 17-55mm f/2.8 has a constant F2.8 max aperature, you don't have to worry about the depth of field increasing as you zoom. It is so confidence-inspiring to walk around and set your aperture where you want it to give you the depth of field you want, and not really worry about the shutter speed being too slow. Some of my outside dusk (low-light) shots at 1/6 sec shutter and F22 came out sharp (Thanks again to IS). I almost got vertigo when I first looked at my pics uploaded to my PC--they were so realistic. Images really pop!

The decision to go with this lens instead of some of the "L" grade lenses involved the following criteria:

1. Focal Length Range. I wanted at least the range of the 18-55mm kit lens.

2. Max Aperture. I wanted f/2.8, since f/4 is too confining for low-light situations. Also, f/4 doesn't give you the depth of field limiting ability of f/2.8. Trade-off is size and weight (and price).

3. Constant Max Aperture. I wanted a constant max aperture throughout the zoom range. I don't want to set the aperture and have the camera stop it down due to the max aperture decreasing as you zoom in (as is the case with the kit lens).

4. USM. I wanted the Ultrasonic Motor (USM) feature, since this is known to be the fastest and quietest autofocus technology.

5. IS. I wanted Image Stabilization (IS), since this effectively makes your lens faster, because you can shoot in lower light at lower shutter speeds without fear of blur (provided the subject is still). Also, zoomed-into 55mm, camera shake can be more of a problem than at shorter focal lengths. IS has got you covered there as well. This lens only has one IS mode (no mode for panning).

6. Full Format or Crop-optimized. It is true that going with a full format lens would mean that you could use it on any DSLR (35mm film, APS-C DSLR, and Full Format DSLRs such as the 5D and 1Ds Mark II). However, full format lenses are not optimized for the 1.6x crop of the Canon DSLRs Rebel through 30D. The crop-optimized lenses (designated by the "EF-S" in the model name) are tailored to the smaller image sensors of the APS-C camera bodies. The lens elements and coatings are designed to minimize the ghosting and flare that can come from reflections off of the image sensors in digital cameras. Also, the crop-optimized lenses tend to be smaller, lighter and less expensive than otherwise identical full format lenses. I considered the EF 17-40mm f/4L, the EF 24-70mm f/2.8L and the EF 24-105mm f/4L. But, none of these had the focal length range I wanted, and two of them weren't fast enough (f/4), and the EF 24-70mm f/2.8L was very heavy (2.1 lbs). I determined there was no need to sacrifice performance now for some possible benefit later on if I purchase a full format camera. If I ever do, I would hope there would be full format lenses that have been designed to limit chromatic aberrations and introduce other digital optimizations currently provided by the crop-optimized APS-C format-only lenses. Besides, you can always continue to use your old camera and lens as a back-up, or you can sell them to help purchase the new ones.

7. Grade ("L" series or Advanced Amature). Of course, if all else is equal, take the "L" lens with the red stripe. But, all else is not equal. I'd rather have an optically superior lens that is well-built (although not as well as an "L" series) that meets all my other criteria, and just be careful to keep the dust out. The EF-S 17-55mm f/2.8 is expensive (I paid $[...] on [...]). But, I'm sure if there were an "L" series version of this lens, it would be even more expensive.

Conclusion: This is one great lens! There's nothing else out there for 1.6x crop digital cameras that gives you the sweet spot of zoom range, low light capability, depth of field control, image stabilization, fast and quiet auto-focus, and superior image quality rivaling prime lenses. And to put the considerable weight (22.8 oz.) into perspective, it is still 3.8 oz. lighter than the very good digital-only Nikon 17-55mm f/2.8, and the Nikon does not even have image stabilization (and costs more to boot). Game, set and match!

UPDATE 2/3/07: I've taken 1000+ pictures. I'm impressed with battery life given that I thought IS would use a lot of power. But, since flash is nearly never needed (due to f/2.8 and IS), battery life has seemingly been extended. I didn't realize how much I would grow to expect a stable image through the viewfinder until I looked through a viewfinder with a lens without IS and saw the image shaking. Note that cameras with built-in image sensors (such as Sony Alpha) don't stabilize the viewfinder. The EF-S 17-55mm f/2.8 IS USM autofocus locks-on amazingly fast even in low light. No apparent optical weak spots at any focal length or aperture. Lens hood (optional) eliminated most, but not all, flares from bright sun. I think this is the best, most versatile walk-around lens you can get. I wish Canon would make an EF-S 55-200mm f/2.8 IS USM lens to pair it with so I could zoom in closer on distant wildlife, etc.

The best Canon EF-S 10-22mm lens I own

Canon EF-S 10-22mm lens

I have had Canon EF-S 10-22mm lens for several months now and let me start out by saying WOW. I looked at the lens in the store along with the Sigma 12-24 and I was in total awe of what I saw though the view finder with the Canon 10-22. This is an ultra wide angle lens that is incredible. I went home and thought about where I would use this lens and determined that I would use it quite a bit. I went ahead and bought the lens and I continue to be more impressed with it every time I use it. I have used the lens for both close-up (which can give you some very interesting distortion shots)and wide angle shots with great success.

The 10-22mm is equivalent to 16-35mm field of view using a canon 20D which is not a full frame sensor. With a minimum focal distance of .24m (about 9.5 inches) you can get very close to objects and still get alot of focal width in the photo. There is incredible clarity in the lens. The photos I have taken are very clear with only a slight hint of softening at the corners at 10mm; everything else is sharp after that. There is a little barrel distortion at 10mm but everything else up to 22mm is nice. I have not gotten any light flare in my photos. The Ultrasonic motor is very quiet. The depth of field is outstanding. A slim UV filter helps prevent some slight vignetting at 10mm. With a maximum aperture that ranges from f/3.5 to f/4.5, the Canon EF-S 10-22mm f/3.5-4.5 USM Lens is a medium speed lens. I would recommend using a tripod if you are at all unsure about your ability to hold the camera still for action shots with this lens. The lens it's self is fairly light weight. If you are going to use filters the lens requires 77mm.

The lens can produce some interesting distortion shots if you are taking close-ups and are not perpendicular to the object. For close-up shots with out distortion it is best to be perpendicular to the object.

Inside the lens housing there are three aspherical lens elements and a Super UD element that produce clear vibrant shots. The lens it's self sturdily built and comfortable to handle.

Impressive Canon EF 70-300mm Lens


Canon EF 70-300mm f/4-5.6 IS USM Lens for Canon EOS SLR Cameras



 Canon EF 70-300mm f/4-5.6 IS USM Lens for Canon EOS SLR CamerasCanon EF 70-300mm f/4-5.6 IS USM Lens for Canon EOS SLR CamerasCanon EF 70-300mm f/4-5.6 IS USM Lens for Canon EOS SLR CamerasCanon EF 70-300mm f/4-5.6 IS USM Lens for Canon EOS SLR Cameras
Canon EF 70-300mm Lens

 I bought Canon EF 70-300mm Lens as a replacement for the earlier 75-300mm IS lens. I was generally happy with that lens, but it had definite limitations - I needed to shoot at f8 or f11 and bump up the ISO to get a decent shutter speed.
This new version seems sharp at full zoom even wide open, allowing me to use a lower ISO setting. Size is similar to older version, but the IS seems more effective - looking through the lens when it kicks in you can actually see the image become more stable and less shaky. I got this over the Canon 70-200 f4 L because of the extra reach, smaller size (slightly) and the images I've seen from both are very similar.


UPDATE: There have been reports of soft images when using this lens in a verticle orientation - however I have not experienced this on my copy. I'm happy to say that after months of using this lens, I still consider it great.

My walkaround Canon EF 17-40mm lens


Canon EF 17-40mm f/4L USM Ultra Wide Angle Zoom Lens for Canon SLR Cameras

The walkaround Canon EF 17-40mm lens. This very topic leads to a heated discussion among DSLR photographers.

First, determine your budget, focal length, and aperture needs.

If you frequently find yourself zooming out to get everything in a frame, you will want a wide angle lens such as this. If you frequently find yourself zooming in, this is not the lens for you. On a full frame body such as Canon EOS 5D, this lens becomes ULTRA wide angle. On an APS-C crop body such as Digital Rebel XTi (which I used for this review), it becomes MEDIUM wide angle. But thanks to 1.6x crop factor, this lens expands to more usable 35mm equivalent focal length of 27 to 64mm.

Second, audition the lens if you can.

By definition, a walkaround lens should be relatively portable. At 1.1 lbs., Canon's EF 17-40mm f/4L USM is neither super light nor neck breakingly heavy. In fact, it weighs almost the same as Digital Rebel XTi -- really nice balance. The lens feels very solid with supreme build quality that only L-series lenses offer. Although this lens is weather proof and therefore sealed against liquid and dust, I strongly recommend getting a 77mm filter to protect the front lens element. With it, this lens is made to last.

In terms of looks and feel, it doesn't get much better. Its rubberized full-time inner focus manual ring USM focuses smoothly, quietly, and quickly. Since it's inner focus, the lens will not extend beyond its metal casing whether you zoom in or out. The focus window shows focusing distance from 0.28 meter (0.92 feet) to infinity. The focal length marker indicates 17, 20, 24, 28, 35, and 40mm. The lens exudes quality from tip to tip.

You may tolerate heavier lens or may not mind lesser build quality of cheaper lenses. A walkaround lens will be used very often, so make sure you will be comfortable with it.

This lens is famous for saturated color and deep contrast. Its images are simply stunning. At 17mm wide angle, barrel distortion is noticeable but relatively mild. From 24mm to 40mm, its images are distortion free and perfectly suited at capturing people.

Vignetting (corner darkness) is minimal with mild chroma abberrations (color shadows). At f/4 aperture, details become noticeably softer toward the edges. The center region is very sharp and at f/5.6, edges remain fairy sharp. Thanks to 7 diaphragm blades, this lens can produce very nice bokeh at 40mm (blur effects).

One of the most cited weaknesses is the f/4 aperture. In my experience, a bump in the ISO speed and steady hands are all you need to take well focused images indoor. On the other hand, if you are shooting with very little amount of light, you might wish for f/2.8 or image stabilizer. Although the difference between f/4 and f/2.8 is just 1 stop, my other lens, Canon EF 24-70mm f/2.8L USM (too heavy to be my walkaround lens) easily outperforms in such challenging situations. But by and large, I was not handicapped by the f/4 aperture.

Some of the main competitions (sorted by price):
- Sigma AF 17-70mm f/2.8-4.5 DC macro: Good zoom range with macro, and generally solid performance if you can get a good sample. It does suffer from a bit slow focus mechanism, soft corner, and chroma aberrations. Works only with EF-S mount.
- Sigma 18-50mm f/2.8 EX DC: Very good value for f/2.8 aperture, but Tamron's 17-50mm is a bit better lens overall. Works only with EF-S mount.
- Canon EF-S 17-85mm f/4-5.6 IS USM: This "traveler's lens" has a wider focal range than most wide angle lenses (widest among Canon) and is equipped with an image stabilizer. While it is a Jack of many trades, it is the master of none. Every lenses on this list will perform better at particular focal length. Then again, none of the lenses on this list has as wide focal range. It is famous for extreme barrel distortion at 17mm and chroma aberrations. Works only with EF-S mount.
- Tamron SP AF 17-50mm f/2.8 Di II LD Aspherical (IF): This is the most direct competitor. It takes sharper images with faster aperture while costing less. Both the build and focus mechanism are significantly worse, but should be good enough for many. Works only with EF-S mount.
- Canon EF-S 17-55mm f/2.8 IS USM: This is THE reference, if you can afford it. Its images have razor sharp details and great performance all around (minus vignetting, which is typical of EF-S lenses). The build quality is worse than L-series but still pretty good. Works only with EF-S mount. This is the best EF-S lens hands down.
- Canon EF 16-35mm f/2.8L USM: One of the most expensive wide angle zoom lenses. It's larger and heavier, but has f/2.8 aperture.

This is how Canon EF 17-40mm f/4 USM stacks up.

Pros:
- Among the very best build quality.
- Excellent, buttery smooth, super fast front-focus system.
- Top notch color and contrast. Very sharp center resolution.
- Almost non-existent vignetting, generally low distortion, and well controlled chroma abberrations.
- Ideal weight and size for walkaround purpose

Cons:
- Edge softness at f/4 aperture.
- Narrower focal length than most competing lenses.
- Slower than some third party lenses.

All in all, this is an excellent wide angle walkaround lens. It may not offer the most bang for the buck, but if you value full frame compatibility (EF lens mount) and excellent build quality, this is the default choice. This lens comes with a nice pouch and a lens hood. I find the hood to be somewhat ridiculously shaped and because the lens is resistant to flare, I do not use it often when shooting outdoor.

All I bought at the price $719.99 dollars from website amazon.

First Time Zoom Canon EF 75-300mm f/4-5.6 III Telephoto Zoom Lens

Canon EF 75-300mm f/4-5.6 III Telephoto Zoom Lens for Canon SLR Cameras

 Canon EF 75-300mm


 I'd just got into SLR photography and the first few months with the 35-90 lens that came with the Canon Rebel 2000 were outstanding. I never realised there was SO much difference between a point-and-shoot and an SLR. After reading p on some of the books about photography, I reaslied an important point was getting the right framing and getting close to the subject. So I set out to look for a cost effective zoom lens that would give me that flexibility. I tried the cheeper rip off lens in the loal camera store and found their mechanisms stiff and slow focussing. I stuck my neck out for a canon make lens, and this one jumped out at me. It's perfect, the shot are crystal clear, the zoom is smooth and the autofocus is just as good as with the smaller lens. How do they make these lenses so cheap when competing lenses are more that twice the price? highly recommended for a novice like myself whodoesn't want to sped too much for telephoto zoom capability. I'm now looking for a canon 2x teleconverter to add to my range.

All I bought at the price $128.23 dollars from website amazon.
