Carlos, I fully understand what you mean. In my case, the lens is crystal-clean, and this was the main reason why I accepted a partial refund and that I kept the camera. I would not know whether it would be worthwhile to mail Harry the camera for [hopefully] a similar statement on my lens. I will take a roll of film with it tomorrow. Raid Raid; Identical lenses about design and construction could have differences even brand new, if you add factors like maintainance and use for an old lens, differences can increase dramatically, and then my opinion is only valid for my camera and lens. About my 3.5F Planar 3.5/75 six elements, this lens was the only reason I kept the camera when I received it, the camera working condition was not according the seller description and he offered me to return my money, but in fact the camera was very cheap really and then I thought about Harry Fleenor to repair the camera because the lens looked excellent except for a thin fungus ring in the first element around the edges, no important really and Harry has a lot of spare parts if necessary. Harry sent the Planar to John v.S. in Colorado and he removed the fungus without problem, it was not necessary to recoat the first element. Harry authorized me to comment his opinion about my Planar :"...While I was adjusting the focus on the Rollei collimator I was impressed by the sharpness of the lens on this Rolleiflex 3.5F". Please note Harry wrote on "this" 3.5F, you couldn't take it like a general commentary about every Planar on every 3.5F. In practical use, I only could say this Planar is an excellent lens.
