Originally posted by Adam Since the lens doesn't have an aperture ring, problems with exposure will probably cause you a lot of headaches later down the road. Despite the low price, I would either seek compensation or return it. One option would be to get it repaired. Even then you'd be getting a great deal!
Thank you Adam, I live in Bergen, Norway. I have sent an email til Ole (your mate from Copenhagen) with the question about where I can get it checked somewhere close to here. When I get the focus nailed and get the right exposure (got it now many times), it is fantastic. Thank you for your advice
