H137 #5 Orion 15 28mm f6.0
I stuck the Orion 15 28mm f6.0 on the Bessa R4M. Lightweight package and the lens is OK. The weather co-operated - most everything had to be shot at f6.0!!! The Orion is OK stopped down, comes into its own at about f11. I also suspect that the focussing cam and the R4M is slightly mis matched. Not pin sharp. I have used it on M4P's and M2's and it works better with those bodies. more testing needed - and preferably, more sun!
