Hi, would you be interested in trading (+ cash) for a ZM 21/2.8? It works great on the M9 and no doubt on the M8 also. Excellent condition, no fungus, no bright mark.
I also have the Zeiss 21 finder which must be seen to believe. Much brighter than anything else.
I am in California. If interested, how about trade + $340 for the finder and the cost difference between the 21 and 24?
