I take pictures on mostly small items such as jewelry for my clients, need to get some close-up details, so in this case I assume it doesn't make a difference which camera I use (T4i, T3, or T2i)? is the 60mm macro lens the right one for my purposes?
or does it even matter if I use a DSLR camera or not? would a good point and shoot still give me the same result if there is good lighting?
60mm macro is good for full frame but 100mm macro is better for crop sensors...ie t2i,3i,4i.
Also you wont see much difference so long as they are all shot with a good amount of light which id assume they are. the t4i is substantially better in low light situations though.
