I have owned a Canon Rebel XTi (400D) for almost a year ... and while it's
a darn nice camera, I was looking to upgrade and anxiousely waiting
the Canon 40D to be announced -
a side-by-side review of the Canon40D versus the Rebel XTi is below.
So a few days after the 40D announcement, I placed an order with Amazon on August 26th, 2007. That turned into quite a ordeal - read more about the
Amazon Canon 40D saga. Given how popular the camera is, not surprising
there were some delays - stuff happens - but I was happy to receive it
by September 6th. Below are some of my hands-on experience with both cameras.
The Canon 40D and Canon Rebel XTi have some similar characterists which include the same 10 Megapixel APS-C size sensor of 22.2 x 14.8 mm (1.6x focal length multiplier accepting both EF and EF-S lens) ... although the former is a different design with claimed better IQ (Image Quality) at high ISO. the 40D also had a top "settings" LCD, three custom settings, and a rear wheel that I use all the time. Both have pop-up flash with GIN of 43 feet and built-in dust cleaning. Some differences/improvements are shown below with links to more information. In summary, while the Rebel XTi is a nice camera (which I sold), the Canon 40D takes it up a notch and it is a ton of fun to shoot ... and after using it for a while, it would be very, very difficult to go back to the 400D for me. ... and I'd still take the 40D over the subsequently released 450d although the announcment of the Canon 50D (upgrade to the 40D) is pretty interesting.
|Feature||Canon 40D||Canon Rebel XTi (400D)|
|ISO||100, 200, 400, 800, 1600, 3200 (H)||100, 200, 400, 800, 1600|
|Canon 40D has less noise with improved micro-lens design - lots more info/pictures at the Canon 40D versus XTi High ISO Shootout!|
|Auto-Focus||All 9 cross-type with center high-precision/diagonal||9 focus points - center only is cross-type|
|Noticeably faster and more accurate. Note that high-precision only kicks in for f/2.8 or faster lens - more info
on Canon 40D autofocus.
Also new to the 40D is Canon's Live View which allows a real-time view on the LCD of the CMOS image.
|Continuous Shooting||6.5 fps or 3 fps up to 75 jpegs||3.0 fps up to 27 Jpegs|
|The 40D is a machine gun that goes on forever - I get 89 JPEG's with my Sandisk Ultra 2 card!
However, if you turn noise reduction on - CFII.2 - I only get 7 shots before it slows to ~shot/second.
Hear them them side-by-side in the Canon 40D Continuous Shooting Speed page.
BTW, there is no UDMA support, so the fastest CF card is probably the Sandisk Extreme III.
|Viewfinder Info||95% coverage at 0.9x magnification||95% coverage at 0.8x magnification|
|40D looks much brighter/bigger ... especially appreciated by "older" eyes. Also shows ISO - yea! Mirror Blackout (59msec) is noticeably shorter.|
|Remote Control||N3 connector - Wireless||E3 connector, InfraRed|
|The XTi worked with the RC-1 InfraRed remote which is small and about $20 ... very handy for short range line-of-sight and can attach to neck strap.
The 40D uses a longer range radio wireless remote. The LC-5 is big and $300+ ... but there are small and cheap 3rd party Canon wireless remotes.
|LCD||3.0" (230,000 pixels)||2.5" (230,000 pixels)|
|Bigger screen is nice - shame it's not higher-res like all the other vendors are doing|
|WeatherProofing||Battery and storage compartment doors||None|
|See WeatherProofing pictures - surprised Canon didn't try harder on this one|

The Canon 40D is an impressive camera at a decent price point. But what would make the Canon 40D even better - i.e. what would I like to see in the Canon 50D follow-on?
