Leica summicron 35 f2

[babaky]

Hi there

I am looking to buy a scremount Leica summicron 35 f2.
Need some help though as looking at the limited information, there were only 500 made in germany, and some unknown number in canada.
Looking at the serial numbers on l-camera-forum.com serial numbers, , there seems to be more than 500 ???







Can anyone tell me which range of serial numbers correspond to the LTM summicrons.

Also apparently there are some which have been converted 'with the set screw locked M mount removed'

Can someone tell me what this is and how to look for it?

Thanks

They made some "convertible" mount Summicron, Summaron and Summilux lenses that don't have goggles. It's pretty much an LTM lens with an M mount adapter screwed on with a small set screw into the mount to hold it in place on the lens. If you look carefully at the M mount you should be able to see a small screw holding it in place if it is a convertible lens.

Hi Brennan

I thought it was the other way round???
Due to the rarity of the screw mount, alot of the M mounts were converted to screw mount?

These lenses weren't converted, they were offered with removable M bayonet. They are not easy to distinguish from those with fixed bayonets, they look identical except for the set screw.

Can anyone post a photo of this screw?

Here is a convertible Summaron on a barnack. The second photo shows the set screw (the small one on the right)

There are a few lenses designed to be convertible (don't know if Leitz advertised as such back then). Summicron 35, Summaron 35/2.8 and Super Angulon 21/4 come to mind. They are really convenient if you shoot both M and LTM bodies.

Thanks very much for taking the time to post the photos. I really appreciate it.

Indeed I don't think being 'convertible' was intended at all.

Another to add to the list was the 90mm Summicron.

Glad to help! wish I still had that lens. 🙂
