Nikon D3100, Pentax Kr or Canon T2i?

I'm finding it to be a really hard decision…

is it worth the extra money to buy the Nikon D5100?

Have you gone to a local camera store and tried them all out? The D5100 isn't a huge improvement over the D3100, unless you want the flippy-sreen-thingy. The Rebel is the oldest of the three, but is still a great camera.

Here's what you should do, u r finding it hard coz you haven't done any research.

1) Test them out in stores.
2) Rsearch reviews, pros n cons.
3) Research the brand's accessories mostly lenses.
4) Look for side by side video review.
5) Long term value or reselling value.

Before you do any of this research, learn the basics of dslr photography.
