As per the sticky above your post:

I have used Don Goldberg and John van Stelten for Leica reapir - both excellent. The Jupiter is quite a simple construction and any competent technician should be able to tackle it. If I may guess - your focusing ring is stiff? The Soviets must have used very long-setting glue instead of lubricants on their lenses....

 

Best,

It might be a good idea regarding Jupiter to find their serial number in dates made. Most are quite poor, regardless one might give the look you want. (After all, my favorite 50mm lens is a post WWII Summitar.)

 

In other words, it might be less fuss and time to just buy another one or two at their penny-to-the-dollar price compared to Leica equivalent focal lengths/f-stop, then choose the better. Heck, buy five!

Who services old Russian Jupiter lenses in the U.S? How can I contact them? Thank you.

 

YOU are the one - so just ring your own phone number ;-)

 

Not kidding, there is a perfect instruction available by Brian Sweeney:

Because these lenses are so cheap, I would try to the service by myself - if it is not working, you just have spent 20 Dollars for the lens, and two hours of your lifetime, but learned a ot - at least, that you are not a camera repairman.

 

But normally, it should work, and you have a big reward: A self serviced lens. Try it out - its nothing magic, just concentration and work. I tried it out by myself, with a Jupiter 3, and it works. Have had misfocus (cant remember if front or back), and the lens was very stif, and not smooth.

 

With a set of small phillips and flat srewdrivers available at any DIY store, a toothbrush, some cleaning stuff and non acid grease I did a very nice CLA job - and it was a pleasure to use the J3 afterwards.

 

Cheers, Andreas

All right then. You guys have convinced me. I will try my first CLA of a lens and learn something. I will go on Brian's website.

 

Be careful though, there were at least 4 versions of the Jupiter 3 (f:2/50mm) - if that is indeed the lens you have. So far we have not shared which Jupiter you have or, what is wrong with it either.... ;)

 

The f:2/50mm Jupiter versions differ quite a lot, with some having rotating mounts and some parallel non-rotating mounts. The non-rotating versions have more complicated helical mounts - not insurmountable but, I just wanted you to be aware of that. Google is your friend - that is how I found much of the information to help me with my Jupiter issues.

 

Good luck,

 

Jan
