My Rolleiflex 2.8C is now starting to show quite a bit of deterioration in the taking lens. The coating is almost non existant and it looks like there may be a bit of separation starting. Outside it is quite difficult to use in brighter conditions with very low contrast and very prone to flare.
In addition I would also like to get a CLA on it as I think the sutter speeds are a bit slow.
Is very any facility in the UK for recoating/repairing the lens and is it cost effective? I really do love this camera and would like to get it fixed up.
A re-coating of a cemented doublet can be very cost inefficient and potentially giving bad results (you see, they have to remove the old coating, take away the old cement, coat all four surfaces, and re-center & re-cement the doublet). The risc of lens breakage during the heating needed in coating process is also high. But if your Rollei has a Planar-like lens, the front element should be a single lens - maybe you observe the separation in middle elements? That sounds worse... maybe it's easier to find a new lens for your camera? I understand that it's not easy and cheap, but it definitely can be much cheaper compared to re-coating task.
I got a fine LF lens - Fujinon-W 5.6/210, whose coating on a front lens was very very badly ruined, but it was OK on all other elements. I polished the front surface with some optical ultra-fine abrasive paste, the most of the coating was gone - and I see now no flare or contrast issues with this lens. Looks like the front cell coating is not all this important
