Multicoating old lenses

[tom_keenan]

Is it really possible (and practical) to coat older uncoated lenses? I shoot 8 x 10 and I love my big giant 210/8 SA and the 360 Symmar-S. Both lenses were made in the 50's. Is there a reliable place that can apply multicoating?? Is there an S Grimes of the coating world??

By the way, Is there a search function to this message board?

thanks

I don't know the Symmar that well, but you'd be crazier than I am to

get the Angulon multi-coated.

The major difference is between un-coated and coated. Although there

is a difference between an M.C. and an S.C. lens, all else being

equal, it's just not worth the cost.

Now, if you had an un-coated lens of good quality that you got at a

good price and that had enough air-to-glass surfaces to actually

benefit from a coating job, then, yeah, knock yourself out.

Personally I think that defeats the whole purpose of buying older

glass in the first place - SAVING MONEY!

It's probably not a realistic proposition. Although most spectacle

lens manufacturers have multi-coating facilities these days, and you

could possibly get the job done at a reasonable cost; there's the

dis-assembly of the lens to consider, and what the heat of the coating

plant might do to the edge blackening and cementing of the elements.

If the rim blackening was damaged it could cause more flare than the

multi-coating would reduce. You've also got the very good chance that

the lens wouldn't go back together perfectly, and sharpness would be

affected.

Altogether, not worth the risk I'd say.

Check with Steve Grimes at skgrimes@skgrimes.com. His website

(http://www.skgrimes.com/) doesnt mention coating, although I thought

he offered that service as well. If not, maybe he can give you a lead.

I think that if you have a Symmar-S it was made in the 70's not 50's.

And most Symmar-S lenses were multicoated. You can check the age of

both of your lenses on the Schneider web site.

I recently had my APO Lanthar 150 recoated and though it was only a

single coating it solved the problem of severe cleaning marks

sustained from the previous owner. I used John van Stelten and am

very happy with his work. The cost was $225 + shipping. I am not

sure if he does any multi coating.
