What camera , does it fit? .....................................message ends........................................
With a simple, low cost adapter this fully manual (the old fashioned way) lens will work on your current SONY. There will be no electrical contacts. I use several MD lenses on my SONY a6300, they work just like they did 50 years ago.
i'll donate the lens as i didn't pay that much 4 it. I'll be very careful nexttime ..........................................reply ends.................................................
