Canon EOS 30D

Image

This camera offers a few well considered improvements over the 20D it replaces. The sensor and processor are the same so the image quality will not differ one iota, BUT an enlarged LCD monitor, spot metering, vastly improved shutter life and ISO displayed on the viewfinder are worthy improvements easily justifying the upgrade from the 20D. If one is considering an upgrade from the 10D my advice would be to definitely go for it. The 20D and 30D both have the "instant on" feature and this represents a vast improvement over the 10D. The 10D was felt by many to have focusing issues and though I did not have any significant problem with my 10D in that regard the 30D represents a substantial improvement in this area. Canon still is not offering (in this price range) a camera with eye control or 45 focusing points, BUT the nine focusing points that ARE offered are well placed and the camera focuses quickly and surely resulting in tack sharp photos.

The pictures this camera takes are simply beyond belief. Beautifully saturated, tack sharp, NO, and I mean NO noise at 400 or below and barely discernible noise all the way up to 1600 ISO. For all practical purposes 1600 ISO is an entirely usable speed resulting in fantastic pictures. What Canon has accomplished in reducing noise and increasing pixel density proves that they are, for now, the technology leader. Canon for now is doing a better job at controlling noise than Nikon though Nikon with the D200 comes pretty darn close except at 800 ISO and above.

The new flash system, ETTL II, available first on the 20D is a vast improvement over previous systems. The in camera processing results in exceptional and pleasing pictures. This camera has a fixed continuous shooting rate which was not present on the 20D. The megapixels stay constant at 8.2 million pixels. Many may be disappointed that the MP count was not increased and feel that perhaps a nominal increase to 10MP would have better justified an upgrade. Canon obviously feels that noise and other features are more important at this point than raw MP's and I would agree. The holy grail of digital photography is now dynamic range. And while this camera offers no improvement in dynamic range I think we can expect to see such improvements in future offerings from Canon and the other manufacturers.

One of the greatest things about digital photography is the ability to build a digital dark room for next to nothing. With the included Photoshop Elements you are well on your way to producing pictures that you could only have imagined in the pre-digital days. I am able to recoup pictures that I never would have considered salvageable before this camera. And while Elements is a great program and more than adequate for most needs I would recommend considering Photoshop CS2 for those who intend to plumb the depths of this hobby.

Another thing I like about Canon is the lens system which IMO is second to none. Also, Canon continues to innovate at a furious pace driving the price of these digital cameras relentlessly downward. This camera is being introduced at a lower price than either the 10D or the 20D. The 5D is plummeting in price and is approaching my "strike point" for purchase. I expect that we will see a sub $2000 10 MP camera with a full frame sensor in the next 18 months. Such are the economics of digital photography. It would seem that Moore's law is driving the prices down inexorabl.

Every function optimized for fast RAW and JPEG capture
The EOS 30D is one of the fastest cameras Canon has ever produced. Incorporating the fast operation of the EOS 20D, the 30D allows users to specify high-speed 5 frames per second (fps) or a new low-speed 3 fps continuous shooting for more controlled shooting and/or to save space on the CF card. And it can capture up to 30 JPEG and 11 RAW (or 9 RAW + JPEG) files in one burst. Whether it's the 0.15-second startup time, the high-speed mirror drive, the nearly instant 65-millisecond shutter release lag time or the predictive AF focusing at speeds up to 5.0 frames per second, the EOS 30D will amaze and delight photographers who don't want to wait for their camera when they're ready to shoot.

The Canon 30D's continuous shooting function
Shoot continuously at 3 or 5 frames per second.
Direct printing with PictBridge compatible printers
The EOS 30D lets you print beautiful photos with minimum time and effort - directly from the camera. It's compatible with Canon's SELPHY Compact Photo Printers, desktop PIXMA Photo Printers, and even third-party PictBridge-compatible printers.
EOS: The system
One of the EOS 30D's greatest advantages is the EOS system: compatibility with all Canon EF and EF-S lenses, EX-series Speedlites, and EOS accessories such as the Wireless File Transmitter WFT-E1. (Wireless file transmitter and lenses not included--must be purchased separately.) For high-speed processing of lossless RAW images and complete capture-to-print workflow management, the EOS 30D also comes with Canon's latest Digital Photo Professional software.
Battery grip
To extend the EOS 30D's 750-shot (CIPA standard) battery life and increase handling options, the camera is compatible with the BG-E2 battery grip. (Not included; must be purchased separately.) The BG-E2 takes two Lithium-Ion battery packs for up to 2,200 frames or six AA batteries in the supplied BGM-E2 battery magazine. (Shooting capacity with AA batteries is lower when compared with the Battery Pack BP-511A.) For easy vertical shooting, the BG-E2 provides additional shutter release, main dial, AE lock/FE lock, and AF point selection controls.
Software
As well as the latest Digital Photo Professional RAW image processing software, the EOS 30D comes with Canon EOS Solution Disk, containing the new EOS Utility (integrating remote capture software), plus the latest versions of ZoomBrowser/ImageBrowser and PhotoStitch.
The EOS 30D includes membership of Canon's online photo album, Canon iMAGE Gateway with 100 MB of space for image uploads and photo sharing. (Canon iMAGE Gateway is not available in all European countries.)
