In Topic: Nikonos Nikon R-UW 13mm Lens Repair

I would put trying to remove damaged lens coating towards the bottom of the list of possible repairs. Using a solvent to remove the coating would be preferable to abrading it off but to use a lens coating solvent would probably entail disassembly of the lens. Not a casual action. This lens is more complex than most interchangeable lens. There is the water sealing to be dealt with.
Since Nikon doesn't appear interested in doing a repair his options are somewhat limited. They would be.

Replacement of lens

Finding someone with sufficient skills and parts to repair the lens and especially the waterproofing

Removal of whatever the discolouration of the rear element is
Using the lens as is

Disassembly and selling as parts

Finding a garbage can.

Having, years ago, worked in a camera repair shop, I have seen others do this type of work. Always on a last hope basis. And that repair shop shut down this month. Retirement of owner.

 

 

Thanks R-B

 

I had an issue a couple of years ago with several Nikkor lenses having mould problems following a trip to the sweatiest place (I think) on the planet - Sabah rain forest. Foolishly I didn't put them in bags with silica gel. I had huge repair bills from Nikon and two lenses were written off including my beloved 60mm micro.

 

If Brasso might have been my saviour..... (sigh).... what might have been.......

You could just remove the coating from the rear element. A very mild abrasive should work. Try Brasso but do practice on an old filter or junk lens.
Also, look for any local telescope makers in your area. They would have the optical type abrasives that would do the job.

 

 

You can really get mould off optical glass with Brasso?

Hey Simon

 

Looking recently at the Subal website, I think you can install a flash trigger mechanism using either optical or electrical connections.

Thanks Tim. It will be a type 4 housing with type 4 port, so it sounds like it would fit safely. Thanks!

 

OK, if it's Type 4 there is no problem. You can either fit the camera into the housing with the 105VR on the camera. Or install the camera and then add the lens through the housing opening. Either works and I've not found any advantage/disadvatage to either.
