Also Id like a fish eye lense to go with it. Will these cameras be able to attach a fish eye lense

Sometimes we're undecided between a couple of camera models.

The best thing for figuring out the differences and picking the winner is to go to the manufacturer's website and compare the specs. If they are made by the SAME company, you may even find a comparison tool right there on their website.
Carefully read the specs and make note of the differences.
Make sure to get a camera with manual modes (manual, aperture priority and shutter priority), so you have the choice to be as creative as you want to be. Don't worry… The old AUTO function will still be there, too, just in case you can't cope without it.

Nearly always the newer and/or more expensive model actually IS the better one, too, but that doesn't necessarily mean that you really NEED the dearest one. This is the part that is hardest for us to answer, since YOU know much better what your needs are than we do.

If you're still undecided, google for a few reviews and check out sites such as www.dpreview.com or http://snapsort.com/...om/compare.

Doing this work yourself instead of waiting for an answer to be presented has a big advantage for you. It forces you to do some thinking, research and learning. In the process, you become an educated shopper who is much more likely to enjoy his/her purchases instead of regretting the wrong choices a short while later.
Enjoy the journey - that researching part can actually be fun!

Yes, you can get a fish eye lens for any DSLR camera, but don't do it right away. Learn to use your camera properly first, and learn about photography… THEN consider getting a fish eye lens.

P.S. Notice the spelling: lens, not lense.
