Obviously I have a T2i, and I am a beginner. I have the standard Canon EF 50mm F/1.8 II lens and a little Polaroid .42 fisheye lens. So basically it seems like when I take a photo with my fisheye they never turn out well. They aren't crisp or clear, and sometimes I have a very hard time focusing because it just doesn't focus well. Am I supposed to be a certain distance from things? What are some good average setting for taking pictures with my fisheye in normal daylight? Also, I don't feel like my fisheye provides a very big fisheye effect. Should a .42 fisheye lens provide a good fisheye effect? It seems to be hardly noticeable most of the time. Thanks guys.
