Hi,
I'd appreciate hearing from those members who have used both the 21mm
f2.8 MC Rokkor-X and the 20mm MD Rokkor-X.
Years ago I owned the 21mm (sold it) and recently purchased a 20mm (in
the process of repairing it), so I'm familiar with the physical aspects.
I'm curious your opinions on which is a better performer and why.
Thanks,
Rick
