I just purchased an A100, this is my first DSLR and first venture into photography. I own and operate a video production company so I have been shooting video and film for a long time. I am going to be shooting stills for a manufacturing client, they have a huge manufacturing floor that I need to take some pictures of and I am worried about having a lens that is wide enough. I would love to drop six or seven hundred dollars on a really nice super wide lens but I shot my budget on the camera. How are the auxilary lenses, I am interested in a fisheye and wide angle, can anyone make some suggestions, I appreciate the help.
