I have three gorgeous Zeiss Lenses in the Rollei QBM mount (35mm Distagon, 50mm 1.8 Planar and 85mm Sonnar), which I currently shoot with a Rolleiflex SL35. The metering in that is dead, and I prefer metered shooting with an SLR. So they rarely get used.
I know that is not what you asked, but why don't you buy a Rollei SL35(M) or Voigtlander VSL3E. The cost
is peanuts compared with the value
of your trio of lenses. In-body metering, clean lines. So cheap you might even have two just in case.
