Great. One additional question as I read responses then too. Am I correct to think that the EFS lenses DON'T work on full-frame? If this is the case, does their zoom also need to be thought of as 1.6 magnification (despite the fact that they're seemingly made for a cropped chip)?

You are correct, the EF-S lenses has a smaller image circle and will not be able to fill the frame of a FF camera - and I believe they cannot be mounted on one either unless you tweak them.

EF and EF-S lenses are always marked with the actual focal length. An EF-S lens at 50 mm will give the same field of view as an EF lens at 50 mm. On an APS-C camera, that will be the same field of view as you would get with an 80 mm lens on FF, but the crop factor for APS-C is always the same.

On compacts, you will sometimes see the equivalent (to FF) focal length, but not so on APS-C.

If you think the 70-200 mm is a bit long on you crop camera, you might like the Sigma 50-150 f/2.8 - APS-C only, though.
