I owned a Canon Rebel XTi (400D) for almost a year, and then upgraded to
a Canon 40D in September/2007 ... and subsequently put up a page
comparing the Canon 40D to the Rebel XTi. In January/2008,
Canon announced the Canon Rebel XSi 450D ... so I thought it might be
interesting to do a similar
a side-by-side review of the Canon40D versus the 450D Rebel XSi.
The Canon 40D and Canon Rebel XSi have some similar characterists which include the APS-C size sensor of 22.2 x 14.8 mm which results in a 1.6x focal length multiplier accepting both EF and EF-S lens). 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, the Rebel XSi appears to be a nice camera and would make a great entry-level DSLR. It actually has most of the capabilities of the 40D plus a few extra features. Canon could incorporate some of those features via a firmware upgrade ... but I won't hold my breath. And in addition to the 6.5 fps (versus 3.5) shooting speed, the 40D has several improvements that (for many people) will make it worthwhile to spend that extra couple of hundred dollars - examples include a top "settings" LCD, three custom settings, and a rear wheel that I use all the time. And be sure to check how how the Canon 50D compares to the 40D.
|Feature||Canon 40D||Canon Rebel XSi (450D)|
|The 400D and 40D both had ten megapixel sensors - 450D adds two to that in the Megapixel race.|
|ISO||100, 200, 400, 800, 1600, 3200 (H)||100, 200, 400, 800, 1600|
|While the 450D gets the improved micro-lens design, the additional megapixels should result in more noise due to smaller imaging pixels.|
|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|
|Live View||Standard - must flip mirror back down||Standard and Contrast Based|
|Canon's Live View allows a real-time view on the LCD of the CMOS image similar to point-n-shoots ... although this is much slower than the standard auto-focus. While the 450D leap-frogs the 40D in the category, Canon should (but probably won't unfortunately) provide a Firmware update for the 40D that address this.|
|Continuous Shooting||6.5 fps or 3 fps up to 75 jpegs & 17 RAW||3.5 fps up to 53 jpegs & 6 RAW|
|Argueably the bigger differentiator between the two DSLR's. The 40D is a machine gun that goes on forever and you can often exceed that 75 JPEG's with a fast CF card such as the Sandisk Extreme III. Note that if you turn noise reduction on (CFII.2) the shot depth drops dramatically to the single digits.|
|Remote Control||N3 connector - NO Infrared||E3 connector, InfraRed|
|I'm assuming the XSi will continue to work 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 remote solutions.
|LCD||3.0" (230,000 pixels)||3.0" (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|
|Canon Techical Report||40D||N/A|
|Viewfinder Info||95% coverage at 0.9x - Pentaprism||95% coverage at 0.87x - Pentamirror|
|Micro-focus adjustment||no - Firmware Upgrade Please!||no|
|Shutter Speeds||1/8000 to 30 seconds and Bulb||1/4000 to 30 seconds and Bulb|
|Metering||35 area eval, Center weighted, Partial, Spot||Same - Spot added from 400D|
|Processor||Digic III||Digic III (upgrade from 400D)|
|Analog-Digital Converter||14 bit - image just seem sweeter!||14 bit - 400D was 12 bit|
|Top Flash X-sync Speed||1/250 second||1/200 second|
|Mirror||Motor both ways - quicker & quieter!||Spring Up - Motor Down (?)|
|Shots with no flash||1,100||600|
|Battery||Canon 1390mAh Li-Ion||Canon 1050mAh Li-Ion (400D was 720mAh)|
|Weight w/battery||820 grams - 29 ounces||475 grams - 17 ounces|
|Size||146 x 108 x 74 mm (5.7 x 4.2 x 2.9 in)||129 x 98 x 62 mm (5.1 x 3.9 x 2.4 in)|
|Storage||Compact Flash||SD/SDHC Card|
|January/2007 US Prices||$1,150 (Market)||$800 (List - ships April/2008)|
Technology continually leap-frogs, and whle the 40D is the mid-range, the later release date of the 450D means it has many of those features. Some things that I would expect (hope!) to see in the Canon 50D.
