Leica LTM Leica IIIB Lens Options

Leica M39 screw mount bodies/lenses
Fascinating, two lens mentioned, both damaged and no one suggests repairs. Now guess what I'd recommend...

. . . Is it possible to find a thumb advance lever to attach to the factory advance knob?

No. You'd need a ratcheted spring-return lever.

There is however an easy technique for rapid advance. Place your hand so that the knob is between the (spread) forefinger and thumb of your right hand. Drag the forefinger back smartly, all the way. The knob will advance the film fully.

You can buy a Leicavit trigger base for the IIIb (SCNOO) but an M-body would probably be cheaper.

Thanks for the tip. Ill try it next time I am out shooting
 
FSU quality control on threads was woeful. Most though will mount to Leica but some wont. FSU cameras have same thread but more space: wriggle room or slop. My J12 is great on Leicas but the Industar 55/2.8 wont mount. Try and make sure you can return a misfit.

Hi,

A lot of different firms in the old USSR made lenses and so generalisations about them are usually unsound. The logo will tell you who actually made them.

Secondly, the age of the lens and - most important - the use or abuse it got from the previous owner or owners has a lot to do with its condition. A few ham fisted idiots over the last 80 years or so can do a lot of damage to a lens, even one made by Zeiss or Leitz...

And, if you read the instruction book, you'll find the lens mount is shown as having a thread of M39 x 1mm which is not the same as Leica's. So other people may well have damaged it by forcing it on another, wrong, camera body.

Add to this the rogue LTM to M bayonet adapters and you can see how the situation becomes further complicated; especially if the old hybrid thread was copied.

One of the things I like about the old Soviet system is the thoroughness; meaning I know the threads' size and pitch for filters and so on. That's more than you can say for a lot of camera makers.

Regards, David

Dear David,

yes, many got that wrong, even prestigious WESTERN makers, e.g.: Rollei's adapter for LTM lenses has 1mm!
Not sure regarding Corfield, were they using 1mm pitch or the Leica pitch, or something inbetween?

I just bought a Nikkor 35mm f3.5 LTM mount, a tiny lens that is perfect on a walk-about camera, it renders both black and white and colour very well.
