Nikon 10-24mm f/3.5-4.5G ED AF-S DX


Image

I use this wide angle lens on a Nikon D90. I have lenses that cover the range from 10mm to 300mm in 3 steps: 10-24mm, 24-70mm, and 70-300mm. I also own the fairly new Nikon 85mm micro with VR. I am willing to change lenses as needed - no single solution for all day such as the 18-200mm for me. This background is leading up to the statement that I don't use this lens very much. However, when it is appropriate I find it terrific for the price. The angle of view at 10mm is a little more than 90 degrees; this means you can skrunch in a corner and see both walls. This, is rather neat when shooting certain types of architecture and landscape scenes.

When the angle of a wide lens such as this is proper for the job, several other benefits are there because of the lens physics: 1) good depth of field even when hardly stopped down and 2) ability to shoot at relatively low shutter speeds even without VR. The second benefit follows partly because, other things being equal, short focal length lenses are lighter and smaller than longer focal wave lenses. I uploaded (to Amazon) a picture made with this lens at Carlsbad Caverns that was shot at f4.2 and 0.4 seconds. Hand held! Of course I had to brace my body as best I could and was far enough from the subject that a flash would have been silly. I used this lens exclusively in the Caverns because I needed to shot low-light hand-held as well as liking the angle of view. I was not impressed until I got home and started looking at the pictures in Photo Shop. I had already announced that these were practice shots so I'd know what equipment (tripod, etc.) to bring next time. At least a third of the shots in these rotten conditions were useful and some were really great. I can't think of another lens in my bag that would work as well (not even the 24-70mm f2.8 because it's too heavy for this kind of work).

I have owned the 10-24mm for a year now. As said above, I only use it once in a while. But it is always in my bag when I go on a shoot. If I need a wide field of view, I know this lens will do the job and I'm willing to take the time to switch. If I wasn't, I would not be using an SLR in the first place.



Best ultra wide-angle lens for nikon dslrs: 8 tested

Nikon 10-24mm f/3.5-4.5G ED AF-S DX - £670/ $860

With a zoom range of 10-24mm, equalled only by the Tamron lens, this is a worthy successor to Nikon's older 12-24mm lens. It provides a wider angle of view at its shortest focal length, and build quality feels robust, with silky-smooth zoom and focus rings.
The lens features two ED (Extra-low Dispersion) elements to ensure excellent sharpness and contrast, and the ring-type AF-S autofocus is super-fast and highly accurate.

Performance

The largest available aperture shifts from f/3.5 to f/4.5 as the focal length extends through the zoom range. For an ultra-wide zoom, the Nikon proved remarkably sharp at its largest apertures in our tests, and there was little vignetting, making it great for handheld shooting in dull light.
From low-lit indoor shots to sunny landscapes, the Nikon gives extremely accurate exposures throughout its zoom range. Distortions are a little more noticeable than with some lenses. But, then again, these can be tuned out automatically with Nikon's latest DSLRs.

Sharpness

Best ultra wide-angle lens for nikon dslrs: 8 tested
Outright sharpness is best at the crucial ultra-wide focal lengths, and remains consistent throughout the aperture range.
Lab test at f/8
Sharpness at 10mm: 1681
Sharpness at 15mm: 1766
Sharpness at 24mm: 1488

Fringing

Best ultra wide-angle lens for nikon dslrs: 8 tested
Fringing is only slightly noticeable in the 10-15mm zoom range. At longer focal lengths, chromatic errors are negligible.
Lab test at f/8
Fringing at 10mm: 0.33
Fringing at 15mm: 0.35
Fringing at 24mm: 0.96

Distortion

Best ultra wide-angle lens for nikon dslrs: 8 tested
Distortion is well controlled overall, although barrel distortion is clearly visible at the 10mm focal length.
Lab test at f/8
Distortion at 10mm: -3.86
Distortion at 15mm: -0.23
Distortion at 24mm: -0.81

Image test verdict

Best ultra wide-angle lens for nikon dslrs: 8 tested

The Nikon delivers supremely accurate and consistent metering, and acquits itself excellently in all aspects of image quality.

Canon EF 100-400mm f4.5-5.6L IS USM

Canon EF 100-400mm f4.5-5.6L IS USM

If you haven’t shot with Canon “L” series glass, you will (quite literally) gasp when you look at the quality of your images for the first time. This lens is that good.
I bought this lens to photograph birds primarily. To say I’ve been extremely happy would be an understatement. The IS component of this lens will astound you. I’ve also used this lens handheld at air shows as well and quite frankly, when I get home to look at my photos I’m nothing short of astonished at how well image stabilization works. Note, however, that most of my work is done on a tripod to photograph our beautiful feathered friends. If you’d like to see what I’m talking about you can visit my site in my profile or just Google “Christopher Tippins” and see for yourself how the lens performs. All of my recent bird photography and air show photography has been shot exclusively with this lens (see “New Photos”).
Also note that you will further be impressed to the nines when you are shooting at the short end of the focal length of this lens (about 6 or 7 feet, give or take). I’ve shot dragon flies, flowers and various other subjects and the detail is nothing less than spectacular. You will literally be able to count hairs on the back of insects/dragon flies, etc.
I’ve used it on two bodies – the Canon 60d and a recently acquired Canon 7d. It performs superbly on both as is to be expected.
Recently I was doing some shooting at a zoo and pushed the ISO to 1000 on the 7d to get some shots in low light at 1/15 of a second and got some tack sharp images (yes, I’ve had to run those shots through some noise reduction filters, however). I couldn’t believe it.
Note that Canon (and many people) recommend shooting with IS turned OFF on a tripod. While your mileage may vary, I find wind at the 400mm end of this lens to be a factor and leaving IS turned on helps considerably.
Image quality with this lens wide open is also impressive.
Also take note of this: I have a bud who shoots with this lens as well as a Canon 400 prime and I’ll be damned if I (we) can see any difference in the quality of the shots. I also recently purchased the Canon 1.4 telephoto extender (older type II) and I’m equally impressed with how well they work together as well, but that’s another review.
Note that I am of the type of person who is a very harsh (but fair) critic of products in general.
If you’re the same, you will NOT be disappointed in this lens.

Canon EF 70-300mm f/4-5.6 IS USM

Canon EF 70-300mm f/4-5.6 IS USM

Image

Pros:
The optical quality is great, the speed is terrific, and it compares well to the 70-200mm lens that people like to say blows this out of the water (I believe they are wrong – but we will get into that later) and finally, the price cannot be beaten. Buy it.
Cons:
No hood, extends as it zooms, and the quality of the picture in low light situation lessens a little.
The long version:
I am writing this in simple terms. I found several, several reviews on this lens but they were all in technical terms and leaves you scratching your head a little. So, if you are like me maybe this review will help you.
I bought this lens a couple months ago from US1Photo.com (check these guys out. They regularly have significant sales and terrific customer service). I use this lens with a Canon 40D.
I take several types and styles of pictures so I needed a lens that would do the best job at several things and have a very affordable price (right at or less than $1,000). I looked through new, used, third party (Tamron, Sigma, etc) lenses, and read too many reviews and looked at too many images to count, and spent four hours in a photography store playing with lenses before I decided to spend money and take advantage of this lens. All in all I spent about a week’s worth of time in research and testing before I bought this lens.

Edit:
Okay, so amazon won’t let me put a link here. This is how you find me.
~Go to Flickr
~Then type in a “/” then “photos” then “/” and last type in “gman_five0″
And that should take you there.

Test of comment #1:
~The Canon EF 70-300mm f/4-5.6 IS USM does not track moving objects very well and the farther to the end of the zoom the slower the tracking.
(Flickr Gallery page 2)
This, I have found, to be completely wrong. I have used the lens at several sporting events and found that it tracks rather nicely. I was able to track every step of a base-runner from first base to second, slide, and recovery after the play without losing ONE shot.
To see what I am talking about check out my gallery on Flickr. The older ones are NOT done with this lens or camera and taken, actually, several years ago. I will reference the pictures in question.
Safe, Got There By a Mile, Breaking Up That Double Play (please note that as time goes on from the date that this was posted the pictures may have been re-moved). Also, “Safe” was used instead of another shot taken at the same time and angle with a 70-200mm IS lens.

Canon EF-S 18-55mm f/3.5-5.6 IS

Canon EF-S 18-55mm f/3.5-5.6 IS

Image
I only got this lens, vowing to only do “L” glass since using my 50mm f/1.2, because it got a sizzling review in PopPhoto. It’s clarity was just under a $2,000 Nikon lens reviewed on the same page.
I opened the box, and got just what I expected for under $200-a small, cheap feeling lens. It is the first EF-S I’ve owned, and the white mark for aligning it to mount matched up on my Canon 40D, instead of the red mark I usually use.
I haven’t had time to put it through the paces, but I will say that I am really impressed with the clarity of the pictures. I have a crappy Canon 28-135mm that is just pitiful in the clarity department-and that set me back $400! I put a shot of one of my dogs up for this product in the customer images. It’s the one shot portrait of just her head (German Shepherd). Handheld this thing is as clear as my 50mm f/1.2-I swear!
Another thing I didn’t realize is that you can get close to your subject with this lens. No, I mean REALLY close. I can open it up to 17mm and be 4″ from my subject!
As a portrait photographer, I am really thankful to have a killer IS lens to let me play with wide shots of buildings, scenery, and maybe some fun people/pet portraits that differ from my more “sensible” lenses to date.
Thanks, Canon!

Canon Rebel XS 10.1MP

Canon Rebel XS 10.1MP

Image

This review is geared toward complete newbies (such as myself) who are coming from the point-and-shoot world.
I purchased this camera due to a budget constraint and after reading numerous reviews. For what you features you get, you simply cannot beat the price for an entry level DSLR camera. You may have looked at the XSI (as I have) and have been tempted to put forth the extra $100 or so to get that one. If you get down to the nitty gritty between the specs of the XS and XSI, you’ll find that they are very minimally different, and more importantly, those “extra” features will have no bearing on you as a DSLR newbie.
This XS (1000D) model is oft overlooked because so many are praising its “bigger brother” the XSI. But take a look at a side-by-side comparison and you’ll notice not much has been scaled back for this XS. Save that extra money for better glass. I would even be willing to speculate that a future firmware release will address some of these scaled-back features.
PROS
-Currently the best bang for buck you’re going to find (at this time).
-Canon didn’t scale back very much from the XSI
-Some report that the lower MP (10 vs XSI’s 12) gives better image quality because of the sensor (DigicIII).
-Excellent image quality even with the supplied kit lens.
-Easy to use (with some research-effort on your part)
-Canon compatibility — nuff said.
CONS
-Not crazy about the build materials (some sort of plastic). When I purchase things, I plan on owning them for a very long time, regardless of how “outdated” it may become a few years down the road.
-Some button placements for me seem counter-intuitive, but remember, I’m only a newbie.
-Has crop sensor like all of the rebels.
-Live View usefulness is questionable.
In short: If you’re coming from P&S, you will not be disappointed with this purchase. It will meet or exceed your expectations of photo quality and features.

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.

 
All I bought at the price $495 dollars from website amazon.

Canon EOS 400D

This is a lot of camera for the money. The controls are easy to use, it produces very high-quality images, it’s light, compact, and very portable.
Although I thought that after extended use I would really hate the small grip on this camera, I have to say that it really hasn’t bothered me that much. Perhaps this is because I’m using some larger L-lenses on it like the 24-70mm f/2.8 . . . a case where it’s more like the camera is being attached to the lens, and you’re really holding onto the lens more than the camera.
I really like the shutter sound on this camera . . . that crisp, classic shutter sounds more interesting than any of the other Canon SLRs. Although I like the second wheel on the 30D, I much prefer the menu setup on the XTi, and I really prefer the placement of the current settings on the main LCD rather than on the top LCD window as with the 30D. By comparison, the 30D’s top LCD window looks very old-fashioned. The big bright screen on the XTi is very nice and it seems to display colors a great deal better than the 30D does, which seems to have a strange, persistent greenish-cast.
The self-cleaning-sensor seems to work pretty well as I haven’t found any lingering dust yet!
It’s pretty hard to declare any serious shortcomings with this camera, especially when you consider the price, which is quite a bit better than its primary competitor, the Nikon D80. I like this camera a lot (so far), and I have no hesitation in recommending it. I just wish Canon would stop calling this the Rebel, and just let us have it here as the 400D. Having this camera doesn’t make me feel rebellious, nor do I want it to. I just want it to help me take great pictures, and that it does!

Canon EF 50mm f/1.4 USM


 



I bought this lens to take indoor portraits of my nine-month-old daughter using available light. I was tired of the harsh photos produced by the built-in flash on the Canon 20D or Digital Rebel. A bounce flash improves matters great deal, but I wanted to see what could be done with a fast lens.


The Canon 50mm 1.4 gobbles light. It opens up a world of indoor photography that is not possible with a 4.0 lens. The 50mm focal length combined with available light produces natural-looking results. It is exactly what your eye sees. Shadows and highlights are intact. It is a revelation if you're used to the harsh drop shadows and evenly-lit faces produced by flashes. This is a jarring step up in quality from snapshot to "wow"


As noted, focus is soft at /1.4 and begins to sharpen at /2.0 to /2.8. Not a bad thing, though. Some of my favorite pictures have been produced with the aperture wide open. The depth of field is so narrow at this point, that the subject's face is in focus, but the shoulders start to blur.


I use this lens with a 20D. The balance is perfect, the combination feels very professional and responsive. Operation is very simple. Move the camera into aperture priority mode (Av), look though the view finder and adjust the aperture until you see the shutter speed is faster than 1/30th a second (30).


I agonized over the 1.4 vs. the 1.8 versions of this lens. The additional stop does provide more shooting options. Often I'm shooting at the edge of acceptable shutter speed, and juggling both aperture and ISO. Many reviews comparing the two talk about build quality, focus motor speed/noise, etc, but the bottom line for me was the extra stop was totally worth it. If you want to shoot indoors without a flash, get the 1.4. If you simply want a nice sharp lens at this focal length, the 1.8 is for you.


As a father, my only regret is I wish I had this lens earlier. From one parent to another, I'll tell you the price of the lens is irrelevant, as the pictures it produces are priceless.
