I was planning on buying a new DSLR too replace my Fujifilm Point and Shoot, which has horrible shutter lag. I am an ecology major and would like something that can survive hikes and handle shots taken in not optimal conditions. I was considering a Rebal xt , but then decided if i was going to make an investment in a camera I would buy a 20 d then the 30d came out so I might as well purchase the 30. After all that, I read about the Sony alpha which uses Minolta lenses. I have a 210 mm and 55mm for my minolta 35mm and some filters. So i could save alot of money on my normal lense size and have more money for CF cards etc. Im not sure about a first time product and if I'm going to even care that the ISO only goes up to 1600. What should I buy? If Im gonna switch companys its better to do it before I build up more camera equipment, but I was really happy with my minolta fim camera. Has anyone used the new Sony Alpha yet? or is it better to stick with a company that is more proven and buy new lenses? I will also be using this camera to shoot a wedding next year if that makes any difference.
