Hi, I have a small amount of mould and dirt on the inner lenses of my 1953 TLR Rolli 2.8 C.
Is there an easy way of removing these lenses for cleaning or do I have to spend heaps and go through a specialist camera service centre.
Thanks, Phil.

Hi Phil

Rick has some notes specific to the 2.8C here: http://rick_oleson.tripod.com/index-158.html If you remove the front fascia as shown you can then unscrew the front lens group and dissassemble it if necessary. The front surface of the rear group can be reached (WITH CARE) if you have the iris fully open and hold the shutter open on B. It's difficult to remove the rear group from a C without fairly major dissassembly. If you're lucky it may be possible to unscrew it with a suction cup if it's not too tight.

You can contact me directly if you want more help.


Cheers
Wayne

Phil ....

A Rollei 2.8C TLR is a fine camera. If you are not experienced with camera technical work then the straight answer to your question is that your task in hand is NOT easy or straight-forward. Certainly it is not a job for a first-time project.

The required maintenance may not be very expensive. A pro-techie should be able to accomplish all within about one hour ( assuming that what your think is surface "mould" is not something worse.

If you are not experienced with camera technical work - then better to pay the moderate price of professional attention - and still end up with a beautiful camera instead of a paper bag of bits and pieces.

Just my view - for whatever it is worth.

I agree with your comments. For quality cameras it's always a good idea to seek out a pro when you're unsure.

In this case I know that Phil has watchmaking skills and has already successfully carried out another repair on a Rollei.

I have removed the front as per Rick's diagram and taken out the two front sections of lenses for cleaning. The main problem seems to be the front of the xenotar photo lens which looks as though it has fine pitting marks in the surface lens covering. Is this a lacquer or similar sealant that can be dissolved with a solvent and then re applied? or is it a much more complicated
finish, needing the professional hand.
Thanks, Phil.

Pitting of the coating is common on Xenotar lenses of this vintage. It would need to be polished off and recoated if you want to restore it. The coating (commonly magnesium fluoride) is applied in a vacuum chamber.

This is probably only a cosmetic issue unless it's really bad. I had a very bad one polished and recoated by Longman Optical in Tasmania with satisfactory results.

Cheers
Wayne
