I think I'm right in saying that the Bessa's rangefinder mechanism can't focus closer than 3.5 feet. If a lens is capable of focussing closer than 3.5 feet it will disconnect from the mechanism and give a false reading.
Several of the CV lenses also focus closer than 3.5 feet and also suffer from this problem. At distances from 2.5 to 3.5 feet you will need to guess the distance.
From 3.5 feet to infinity the lens should be fine.
