I just upgraded to my first DSLR (T2i), and have a quick question. When using the camera to review the pictures you have taken, is there any place that displays what the focal length was for the picture? I know it is in the EXIF data, but it would be nice to see without having to download the picture to my PC.
I just looked through the T2i manual, and I'm not sure it's possible to display the focal length of a given image in-camera. I thought it would be displayed if you hit the "DISPLAY" button a couple of times, but that seems to be just about the only relevant information that isn't readily available.
Anyone else?
Not as far as I know. You need to remember, or check the EXIF data on your computer later. Or, use a prime lens... [:P]
Is this just the T2i, or is this true for most DSLR's

I was quite annoyed by this at first. By now it is just one of those Canon stupidities I've gotten used to.

After reading some of the reviews of the kit lens that came with my T2i, they seem to indicate that it is sharpest within a certain range. After taking a few pictures, I was trying to see how they fell within that range.

If you want to critically review your image sharpness/focus, the camera isn't the place to do that. Same goes for evaluating exposure based on the image itself - the histogram(s) should become your best friend(s)!
You are right, the camera display is not the place to judge the sharpness of the photo. However, if you know that the lens you are using has a sweet spot, you can use that information to shoot in that range.

I'll point out that with the exception of the prominent barrel distortion at the wide end of a wide/normal zoom lens, aperture is going to have a much more significant 'sweet spot' effect than focal length. On an 18-55mm kit lens, for example, going from f/4 to f/8 will yield a much bigger improvement in sharpness than any focal length you might choose.
OK ---- Thanks
