I have seen many conversions for Contax RTS lenses since all are Zeiss lenses, but those from Rollei may vary, not the mount, but the actual plates. I also have some other rolleiflex lenses and am wondering if it would be possible to convert them for a while and then convert back. I have a rolleinar 28 2.8 lens and am thinking of converting it but have no prior experience with this and am therefore looking for some pointers. Does anyone here have experience replacing the qbm mount on rollei lenses with a Canon ef mount? In your experience is this an easily reversible process?
