EOS 40D vs. EOS 20D

I got my new Canon EOS 40D today. Resolution is a little better. It is a 10 megapixel sensor instead of an 8 megapixel sensor. So, now my images are 3888 x 2592 instead of 3504 x 2336.

It shoots a little faster. Now, I can shoot 6.5 frames per second instead of 5 frames per second. Also, it takes more images before it fills up the image buffer. I used to be able to shoot like 35 frames in 7 seconds before it started slowing down. Now, I can shoot 75 frames in 11 seconds before the buffer fills up.

The EOS 40D is a lot quieter than the EOS 20D. The EOS 20D has a loud shutter, and, when you're shooting wildlife, that's a bad thing. I had deer, elk, and bear look at me when I released the shutter. That's not really what you want. Quieter is better when you're shooting wildlife.

The EOS 40D has the Digic III processor instead of the Digis II processor the 20D had, so the camera is faster. Faster to boot up, and faster to process images.

The new LCD is 3" (diagonal) instead of 1.8" (diagonal). So, the LCD display is enormous, compared to my old camera. Way better. :)

The EOS 40D has an anti-static coating on the CMOS sensor, so dust won't cling to it as much as on the EOS 20D. Plus, the 40D vibrates the sensor to shake dust off of the sensor. (20D did not do this). Plus, the 40D has some new tricked-out software built into the camera that eliminates dust. (Don't ask).

Also, there is now a Live-Preview mode, so that you can see what you're shooting with the LCD display, instead of having to look through the viewfinder. Less expensive cameras all have this standard. For a digital SLR, howerver, it's fairly unusual.
