Hi everyone. I'm not sure I'll get an answer on this as there seems to be little information about the Rollei Sonnar 250mm f5.6 HFT around, but has anyone used this lens for the Rollei 6000 system? The only thing I can find on the net is one user who wasn't too happy with it. I did see some black and white pictures taken with this lens and they looked quite decent. Any opinions? Thnx!
