I want to take pictures of jewelry, which canon rebel camera can do this job?

Can someone help me decide between the Canon Rebel T3 and T5?

they're pretty much doesn't make any different. What you need is lens for jewelry. It's more important than the camera. Macro lens is really great for jewelry.

As hsbn said, all Rebel bodies can handle this but you'll want a lens that will let you get close.  A 60mm or 100mm macro lens would work well.

But keep in mind that any polished metal will behave "like a mirror".   It's usually a good idea to have some "white" and "black" foamcore boards to control the reflections in the jewelry.  These are placed just out of frame but placed so that the reflection visible in the jewelry is the plain white or black board.

Buy the 100mm macro Canon lens.

It is fabulous for close-up shots.
