It's fungus (also on the rear lens). This same was on Orestegor 4/200 (but this lens is much easier to clean) _________________ Canon EOS 50D

I don't have experience with this particular model, but I dismantled lots of lenses. First I would try to undo the front ring (by using a rubber piece). If the front ring is part of the front assembly (as is the case e.g. with CZJ MC Sonnar 135/3.5), the entire assembly can be usually removed by undoing one to three grub screws and either simply lifting or unscrewing the front part. After that, you'll have access to the front lens group (I suspect fungus grows on the last element of the front group here). _________________ List of lenses |

I see the first problem - the ring with the name of the lens is bigger than screw for filters. The lens is built differently than CZJ. And I see only 3 little screws on focus ring plus 7 screws on Rollei mount _________________ Canon EOS 50D

YMMV, but this mount is not that simple to reassemble correctly. If you have a previous experience with QBM lenses, go ahead. If not, better send it to a technician. In general, I prefer to "learn" in poor condition lenses before going to more expensive glasses on the same mount.

I think I won't be removing fungus for this moment. I can't find any information about disassembling. This is one of the reasons. Second one is... I made some photos on the last weekend without adapter.
ISO 100, 1/250s, f4
ISO 100, 1/60s, f4
What do you think about bokeh and sharpness? _________________ Canon EOS 50D

Witaj zgniewany,
That amount of fungus should not have any sigificant impact on image quality.So if you can stand it,leave it as it is.Just store the lens in a dry place with low humidity to prevent further fungus growth.
BTW:pictures look good to me,especialy if they werer taken without an adapter. _________________ shapencolour |
