I think, almost all dslrs are okay today...
well, I would prefer Canon, but that ist just the thing I started with.. okay, and you better never invest in that Nikon crap
just make sure you get a good light around, a tripod as suggested or for food a bean bag will work fine, too..
Most important thing is, that you
can work with it, so go into a shop and try the Camera, doesn't matter wether Canon, Nikon, Olympus or Sony.
It must feel good in your hand and you may have an eye on the costs of all else you need.
