p.2 #1Leica R lens users on mirrorless setup question
Michael, yes, I'll get a bargain one without ROM. I just looked at the MTF charts in Erwin Put's Leica compendum, the Macro Elmarit 60-R performs better than the 50Cron-R V2 and does not have a mid zone dip when stopped down to f/5.6. Not apples to apples comparison, but the 60-R also compares very well to the 50Cron M especially stopped down and very close to the 50Lux-ASPH. You might want to try this lens as well.
