I bought a D5100 about a month ago, an upgrade from a point and shoot. I don't know much about photography but wanted something that could take better pictures of my kids. When I upload my pictures to my computer, view them with picasa and then zoom in on a section, my D5100 pics aren't nearly as clear as those taken with my friend's Canon EOS Rebel XSi. Even my father-in-law's Nikon D50 pics are much clearer, regardless of who took the picture. Pictures on all 3 cameras are taken with auto settings, and JPEG settings/etc are identical. I haven't seen any printed photos yet (I pick up some tomorrow), but don't understand why the D5100 pics aren't anywhere near as clear/crisp as those from the D50 and especially the Canon (both my friend and FIL took pics with the D5100 with similar results). The whole experience makes me want to return the camera, but reviews are all great. Could this be a setting issue? Any other suggestions?
