can this be repaired? Is it worth the trouble?

Please notice the burr (chip) on the body side of the lens. I can barely feel it. I have taken photos with it and I can't seem to see any problems with the prints.

Can this be repaired and if so, is it worth the trouble?

Should I leave well enough alone?

Anyone have any idea how much a repair would cost if it can be done?

Thanks

Roland,

Can any shop do this work like Ritz or is it a specialty? It is really a shame because the rest of the lens is very fine. Not sure how it happened.

You might look for another that has problems with the front element and have someone (DAG, Sherry) make one good one. Pitty, looks like a fun lens.

I bet you will continue to not notice the difference. Keep using it. You might consider taking a black permanent marker and putting ink into the spot (wipe away the excess) so as to minimize flare.

Hmmm... contact John Van Stelten at Focal Point (click on the business name) and send him a smaller version of the jpg you posted, or a description of the problem. He may have an answer for you.

Now... he probably will give you an estimate as well, so it's up to you to accept it.

Good luck!

Thanks,
it might be worth a try.

If you can't see any problems on prints when using the lens wide open, then leave well enough alone.

I vote getting it repaired. My first 35SP produced some weird-looking photos. I attributed it to some focusing problems (which it did have anyway), but when I sent it for CLA, the repair guy discovered a chip in the rear element and replaced that element. Along with the other fixes,it is now a great shooter and the lens is superb. I can't image a chip that bad not causing problems. Take some shots with a strong light source in the frame and see what happens.

Don't repair it! It can't be fixed. You can't see any image degradation. That is great. 🙂

Paint the chip opaque black to stop any light-scattering that would add veiling flare.

thanks to all. I shall persue the "fix". It does have some sentimental value.

Fill it with black india ink. Then see if you are happy with it at the smaller stops.

Simply interchanging elements is not a good idea. Manufacturing tolerences are made up at the assembly stage. An element from another would work OK, but not as good as the original unless you are lucky.

Regrind /polish/coat would be to extensive to get good results.

Unless Canon still has spares, I would not go further ( not likely).

the fix?

the fix?

It seems the majority reccomend "blacking the area". I will give that a try. Nothing to lose by trying.
