I am researching a new lens purchase for my T3i (600d). I am looking at getting either a 35mm or a 28mm. I sortof lean to the 28mm for the little extra width, my issue is does it "fisheye". I don't have the ability to test either of them at this point but I need something a little wider than my 50mm for areas that are a little closer. I really hate that fisheye look which is why I do not have a gopro (yea I have seen where they use software or whatever to flatten it out but I have no desire to mess with that and do not believe it to keep quality). If there is no problem with the 28mm, how far can you actually go down without getting that fisheye look. So although I plan on getting both at some point (provided the 28mm does not fisheye) which is the one I should get for my kit (I currenlty have the 50mm f1.8 ( which I plan to eventually upgrade to the 1.4 and eventually the 1.2 as they have better DOF and a larger focus ring), the kit 18-55 and a 70-200. I am working to get a fixed prime set as am not really a fan of the zooms for personal reasons).
