lens recoating?

Hi All,

 

This doesn't directly apply to Leica's, but the other forum I asked

in had only a few people with experience respond and I think the

Leica group has more experience in this area than other camera groups

so I hope its OK to ask . . .

 

Does anyone have any experience they would like to share about

recoating a lens element? I am interested in hearing people's

experience on having an old coating removed and a new coating applied.

I am not talking about polishing a blemish out of the lens itself,

but, rather just a new antireflection layer being applied.

 

Specifically, would a new antireflection layer applied by a careful

and experienced technician reduce the lens' performance below that of

original factory spec?. The shop I have in mind has a very good

reputation and is Focal Point in Colorado, USA.

 

My email address is "randallcherry@earthlink. net" for those wishing

to reply in private.

 

Thanks!

Randall: There has been quite a bit of discussion of late on this topic. Have you checked the archives? I had a DR Summicron cleaned and recoated by Focal Point a couple of years ago. Cost was about $230.00 and he did a good job. The coating was scratched from years of abuse.

Thanks for the links to the recoating threads. I'd already read those comments.

 

I am finding there are many people with thoughtful and passionate opinions on the subject, but very few people who have actually had a recoat done.

 

From the few people with actual experience who have commented, it sounds like the recoating process turned out well.

 

I was just hoping to hear from a few more people with actual experience to expand the set of actual users's opinions.

 

Thanks!

I had a summicron collapsible recoated by focal point. All turned out great, lens looks and works like new. The lens originally had some fungus damage. Make sure you send it to an expert. Regards, Mario.

Mario, thanks!
