Canon 30D Review by Bob Atkins; created 2006

Canon 30D Review

by Bob Atkins; created 2006
The Canon 30D is an upgrade of the Canon 20D. The two cameras have the same sensor (1.6x APS-C format, 8.2 MP) but the EOS 30D adds a number of new features. Noteworthy are a 2.5" LCD screen, spot metering, RGB histograms and an increased buffer size.


Here are the main features of the new Canon EOS 30D:


8.2MP (*)
APS-C format (1.6x multiplier, 22.5 x 15mm) (*)
2.5", 230,000 pixel LCD display
Buffer for 30 JPEGs or 11 RAW images
Selectable 3 or 5 frames/sec
3.5% spot meter
Camera "wake up" time 0.15s
Shutter lag time 65ms (*)
Flash Sync at 1/250s (*)
ISO settings in 1/3 stops from 100-1600 and visible in viewfinder when changing
ISO 3200 selectable via CF (*)
Luminance and RGB Histograms
Option to disable image sharpening in JPEG mode
Picture Style modes like the EOS 5D
Tweaked AF algorithms, but does not have the extra 6 "invisible" AF zones of the EOS 5D
Direct Print button
WiFi connectivity when coupled with the Wireless File Transmitter WFT-E1A (*)
9999 images per folder (vs. 100 on the 20D)
Compatible with BG-E2 vertical grip (*)
Street price $1399.99 ($1499.99 in kit with EF-S 18-55/3.5-5.6 lens)


(*) indicates that this feature is common to both the 30D and 20D


Externally the EOS 30D is almost identical to the EOS 20D, the only exterior difference being a dedicated "print" button and a larger LCD.

Eyecup Eb
Neck Strap EW-100-DGR
Video Cable VC-100
USB Interface Cable IFC-400PCU
Battery Pack BP-511A

Printed Instruction Manual


EF-S 18-55mm f/3.5-5.6 Lens (included in kit version only, $1499.99)
Note that no memory card is supplied with the Canon 30D. It takes Compact Flash (CF) cards and I'd suggest that you get at least a 512MB card which should record about 130 images in large/fine JPEG mode or about 50 RAW images. A 1GB CF card would be better. The EOS 30D is pretty fast and can take advantage of faster cards, so I'd recommend a card with an 80x (or higher) speed rating to take full advantage of the camera's speed.


Specifications


The full specifications of the 30D can be found on the Canon 30D Specifications page


Autofocus


The EOS 30D uses the same 9-point AF system that's used in the EOS 20D. I couldn't really detect any difference between the AF of the EOS 30D and EOS 20D in normal operation. Canon have said that "...with regard to AF precision, further fine tuning has been incorporated compared with the EOS 20D..", but it's not something that's obvious and my brief testing didn't reveal any significant difference.


Shutter and Flash Durability


The shutter of the EOS 30D is rated by Canon for 100,000 cycles. I think this is also the rating on the EOS 20D shutter, though it's hard to find that number in print. Canon also say they have taken steps to match the durability of the built in flash to the life of the shutter, which suggests that perhaps the flash lifetime may have been increased over that of the EOS 20D. Shutter lag time is specified at 65ms, the same as that of the EOS 20D.


Power Reduction


Through better power management Canon says there should be about a 10% increase in shooting capacity over the EOS 20D. Canon's own numbers predict that a fully charged battery should give 1,100 images at 68F with flash off, or 900 images at 32F. With 50% flash use these numbers are 750 frames at 68F or 600 frames at 32F.


Noise Reduction


The Canon 30D has an auto noise reduction function. It looks at the noise in images with 1-30 second exposure andonly applies the long exposure noise reduction algorithm if the camera thinks it's needed. Since noise reduction needs a second exposure of equal length, skipping this step can significantly speed up shooting when the noise reduction isn't needed.


The Direct Print Button


Though it might be useful for some, I'm not sure how many 30D owners will be printing directly from the camera. I don't think this is a feature that most EOS 20D owners were asking Canon to add! It would have been better if the button function could have been changed via a custom function, for example perhaps optionally selecting mirror lockup. Most direct printing functions can be accessed via the "set" button in the center of the rear command dial, so the real need for a dedicated "print" button seems questionable.


LCD Display

The LCD is now 2.5" (diagonal), the same size as the LCD of the EOS 5D. The larger LCD makes reading the menu items much easier and it's to see finer detail when reviewing images. It's also readable over a vertical and horizontal angle of about 170 degrees, a significantly wider viewing angle than that of the LCD on the EOS 20D. All in all it's very worthwhile improvement over the 1.8" LCD of the EOS 20D.
