Which of these SLR cameras are the best to buy?
I'm a beginner but my major in radio and tv so i plan on investing on a camera for school
which of these are the best
Nikon D3100
Nilon D5100
Canon T3i
Nikon D3200
Canon T3 EOS REBEL
This will come down to opinion and purpose.
The D3100 is a great camera to learn on and the D5100 is an upgrade from the D3100 (both are great cameras). The D3200 has mixed reviews and most people still choose the D5100 over it. The main feature of the D3200 is the high megapixel count, but megapixels aren't as important as ISO quality. Of the Nikons listed I would vote for the D5100. Since you're a beginner these are all good selections. I don't have any hands-on experience with Canon (and maybe someone else can comment further on them), but from specs I would vote for the T3i.

The one that feels right when you pick it up.
