UV curing adhesive as a scratched lens repair?

Kino · Jan 26, 2020

I am going to give it one more try. I didn't have a lens shade for this roll but have since located one and think it might help a bit.

Thinking of shooting a few shots with the lens shade and then trying the India Ink trick for a few shots to see what transpires.

Paul, its great that you got such nice results with y'r 105/2.8 Scratchotar. My 80/2.8 wasn't cleaned with steel wool, but with coarse sand paper. Totally unusable.

Indeed, Dan, there is a limit to how much damage a lens can take before it becomes unusable. In my case, my "Scratchotar" (love that) is still marginally usable. Of course, under difficult lighting conditions, I doubt it would fare so well.

Anyone have a preferred India Ink type they have used?

Well the ink trick did not work; no starter.

The abraded area took the ink quite well, but the abrasions are so shallow the ink is either on or off.

I tried it several times and it would not wipe off the area without a solvent; probably because there wasn't any real original surface area of the lens surface to allow the cleaning cloth to glide over the abraded area and leave ink behind.

I can see how it would work for a well-defined scratch or even a crack, but not for an overall abrasion.

The front of the rear element on Olympus 35 IV's is invariably pitted (badly pitted). The rear surface is always fine, so my best guess it is some issue involving lubricants in the shutter.

I bought some of the windshield repair stuff quite a while ago, but never got around to trying the repair. So many cameras, so little time. :-(

Still don't feel like taking it on?

Impossible to find the hulk of a body below $350 now days and with the imposed quarantine... can't hurt to ask!

Sorry, no.

it’s not a question of feel... I simply don’t have an optical shop with the tools necessary to polish out an optical surface. It’d be like turning a custom screw with nothing but a file, but worse than that because optics require much more precision. And pitch. But as you say, doesn’t hurt to ask!

Ok, thanks for responding.

I don't know why I am even worried about it, as I have plenty of nice TLRs to shoot with, but it still bugs me.

If it makes you feel better, it would bug me too.
