I picked up a voice mail at work today from Precision Camera stating that my EOS-10D had arrived (see this entry). Although I was pressed for time, I was able to swing by the shop to pick it up over lunch. I also picked up a Canon EF 28-90mm f/4-5.6 II USM zoom lens, as I didn't want to cannibalize the wife's camera for her 35-80mm lens.
The camera is slightly larger than a standard EOS body. The controls are very similar to that of an EOS, so if you've used one before (as I have), you can pick up the camera and start shooting right away. One thing I noticed right off the bat was the fast response. Most digital cameras have a fairly slow response when taking a shot. The 10D is very quick; I'm not sure how quickly it takes a shot, but it's certainly faster than my G1 and seems to be faster than our Rebel G.
Since it is an SLR, you don't use the LCD to frame your shots. Instead, you use the viewfinder since it allows you to view your subject directly through the lens. I prefer an SLR specifically for this reason. It gives you better control over the shot.
I still have to read up on all of the features (yes, I actually RTFM believe it or not) so I can pretend that I know what I'm doing. But, so far I am very impressed with the out-of-the-box experience and look forward to using the camera more.
