Filter question for kit lens on DR
Has anyone used a star filter on their DR with the Kit lens (or any other lens) and does the pattern on the filter effect the AF on the camera? If using this filter will it be necessary to use the camera in MF mode? I am asking this because I take a fair amount of night shots and like to use a Star filter from time to time. My 35mm are all manual focus so this isn't and issue with those cameras. I am not able to test this because my current filters are all 52mm and the kit uses a 58mm.
Also, is any one getting any viginetting on the kit lens using a Cir. Polarizer (standard thickness) or should you use a slim line model to avoid?
Thanks in advanced.
