I need expertise here, this is what I'm doing. I have a 35 mm Minolta XG-M. The body will not advance the shutter any longer. I have two excellent pieces of glass for it (all manual lens) and I'd like to use them. Yes, fully manual focus and aperture adjustment will be a result. I'd like to convert to EF mount for my XTI. I'm seeing all kinds of MD to EF adapters, and I don't know exactly what I'm looking for (optical or non optical) Anyone work in a camera store that sells these?
