• Looking for a prime in the 20-35mm range to compliment the 50mm 1.4.

    Looking at

    FD 24mm 2.8
    FD 28mm 2.8

    Anyone have any preference? Digging online suggests both aren't great wide open (to be expected of most 70s/ 80s wide angle primes?) and solid sharpness edge to edge only coming in at F8ish

    Should I put much emphasis in looking for older breech lock types vs newer, more plasticky FDn? The 50mm I have is older, heavier breech lock and feels good and solid, but I'll sacrifice that if the newer lighter FDn types maintain the same image quality if even not feeling that heavy/ solid.

    Could it be more valuable to adapt something M42 in that focal range to FD? Have heard excellent things about the Mir 37mm F2.8 even though would like a shorter focal length.

    Looking not to cap cost at around £100
