Summaron and M Adapter

[naql]

I recently ordered a Leica Summaron 3.5cm f3.5 ltm off of the Bay and remembered that Cameraquest said that the CV LTM to M adapter Type 2 doesn't work with some 35 and 50mm lenses. Will this lens work with the adapter? Is it just a limitation of the adapter on Leica M cameras? Will it mount on R4M?

Thanks everyone.

I use a Voigtländer adaptor (I don't know if it's a Type 2 or not) on an M3, an M6 and a R-D1 without any problems.

The problem is that the adapter fouls the lens infinity lock keeping focus from going all the way. There are adapters with a small cut out area to clear the infinity lock and these work fine. If hard pressed one could file out the area on an adapter to make it work.

I've posted a photo in a previous thread that might explain things better....http://www.rangefinderforum.com/forums/showthread.php?p=808912#post808912

CV adapter Type 1 will work. Or else you might order an adapter from www.fedka.com.

Thanks for linking to that thread Glenn2. I guess I'll either try to dremel the one I have or order one that'll work.

Hope you get it sorted out, the Summaron is an under-appreciated lens that works very well wide open. I used one extensively traveling and while often wishing for faster glass never had a qualm about sharpness.

Most of the shots on this link were done with a 3g and 35 Summaron using Tri-X. Wide open and slow shutter was the norm for the indoor shots.

If the lens is clean and clear inside, most are not, you will like it. If not, get it cleaned and find a proper adapter, Leitz being prefered.

Great bit of info between the adapter versions. I finally know the differences between one that accepts infinity locks and ones that don't.

Since you're using a camera with manual frame line selection, you can use an adapter intended for any focal length. Voigtlander and Leitz made ones with a cutout for 28/90, 35/135 and 50/75. You should be able find at least one, somewhere. Try the 'bay, KEH, Ritz Camera, et al.

I just ordered one from Fedka. It can't hurt to have more than one adapter with more than one M camera. I found B&H has some adapters made by General Brand that have the cut out. They actually look just like the ones Fedka is selling.

you can remove the push down domed infinity lock button on the lens and it will work with the type 1 adapter.
in the old days a lot of photographers thought the lock was a pain and you see older nikkor and leitz lenses with them missing .
there are two small holes on the back . the proper spanner wrench is needed
and you have to keep the domed button from rotateing . there is a spring under the button that is easy to lose . it might be easier to buy the proper adapter .

Picked up the lens at the Post Office today. It actually works perfectly on the Voigtlander adapter.

Beautiful lens by the way. I shone my flashlight through it and it might have a little haze. It looks fine holding it up to my eye and looking through it though. I guess I'll just have to wait to see the first pictures.
