Professional camera for studio pictures! Low Price?

There, I'm wanting to buy a good camera (it doesn't have to be pro), but I have a amazon and eBay business and I'm looking for a good digital camera that can take good clear pictures of the items and to capture the details clearly of the item. I'm not familiar with cameras I've looked on Canon and Nikon, they are both good/great cameras but, it has a downside of AA Batteries instead of rechargeable batteries. I guess that I'm open because I can just buy a charger for AA batteries.

What would you recommend for a good prof.camera but not to spend a lot of money on it.
I have come across a lot of good cameras but I don't know how to buy them.

You never once told us how much you are willing to spend on a camera you want to buy. And if you're looking at cameras that take AA batteries, that means you're looking at cameras that cost less than $100. Makes me less interested in answering the question.

Professional level cameras can be $5, 000. If that's a "low" price for you then great. If not, if a low price actually means under $1, 000 you can get an excellent consumer level dslr such as the Canon
t3i - about $800 currently.

No camera like what you're asking about uses AA batteries - all the batteries are proprietary and will fit only the camera you buy.

If you really want a good camera sorry, but you're going to have to pony up with the money for it.

The problem is that your criteria are mutually exclusive.

Studio work is very demanding, that's why - in the days of film - professionals would use medium - (120 roll) or large format (5x4 in, 8x10 in) cameras, keeping their 35mm cameras for field use.

They got away with it because portability isn't really a problem if your subject can come to you.

Any camera that can be hand-held is of limited use in the studio, you'd need a DSLR (minimum), high-speed lenses and a professional lighting-rig to do the job properly, and none of that comes cheap.

You could probably get away with a half-decent bridge camera, a medium tripod and a couple of budget spotlights - but don't expect prize-winning results.
