Yes, this is a DSLR, so it uses all the regular 35mm lenses. I know it at least uses Canon AF lenses, can't comment on other brands.
Slimboli, be careful of the sites that have them for about 1/2 price. I read on several of my photo forums that they're pretty bad places. The two major ones are B&H Photo and Adorama, these two get good marks from others. I'm sure there are more out there, but these are the only two I know of.
If you do get one it takes a lot to learn how to use, at least use well. I hadn't used a 35mm SLR in many years and this one took me quite a while to learn. The digital point and shoots are MUCH easier to use, but as I've learned don't come anywhere close to the same pic quality. I was surprised really how much effort it took to learn how to use this, I wasn't prepared for it (as numerous others weren't, based on the photo forums!). Fun to learn/use though. I'm still well into my learning process too!
