My ROLLEIFLEX 2.8F with Zeiss PLANAR -- I bought it years ago from a Camera Club member who had bought it from another man who never used it much . I paid £250-00 then found photos were out of focus and the shutter was faulty -- the Viewing Screen had been put in upside down -- I took it to the Rollei Service Center in London ( when it WAS there !) and it cost me £ 50-00 for a CLA so the Club Member let me off the £50-00 fee so I got it for £200-00 in the end and did many Weddings with it .
