I have a Rolleiflex 2.8 F ser.# 2436569 with 80mm 2.8 Planar and all the charts I have seen indicate that it would fit Bay III filters and other attachments. So now I have a collection of filters, Rolleinars, etc. all Bay III and none of them fit. Not even the Rolleiflash. Only the Bay III rubber lens hood fits because it mounts on the outside flanges. One filter marked "38Ø" seemed like it would fit but after I put it on, I discovered it would not come off without inordinate effort (and risk to all).
Is something broken or distorted? I do not see any damage around the rim of the lenses. Do I have an odd model that takes a different size - I have not tried any Bay II accessories. Any assistance would be very much appreciated.
