Which screwmount to M adapter ?


Recommended Posts

Advertisement (gone after registration)

Dear all, 

I inherited several screwmount Lenses and want to try /use them on my M10M.

I bought a Rayqual adapter 50/75. I’d need a second one and a 28 and a 35 as well.
I saw some other brands such as K&F are much cheaper (1/3 of the price !)

Do you have any experience with adapters, which brand do you advise ?

Thanks a lot

Rayqual adapters are possibly the best

A few years ago I bought one made by a company which was, at the time, called Gobe but which has subsequently been re-branded as Urth.

The quality is superb and, a nice pro-environmental touch, for every adapter sold they promise to plant five trees!

This is the current version;

In any case make surethat  the adapter has not got a cutout for the infinity button. The  six-bit reader of your camera must be covered.

For some Leica screwmount lenses you definitely need the cutout, otherwise you won't be able to focus. E.g. the 1:3./5cm and 3.5cm Elmars and the 1:5.6/2.8cm Summaron.

The six-bit reader only has to be covered, if one wants to use liveview and/or want's to apply a manually selected lens detection code from the menu. Usually there is no necessicity for either with screw mount lenses. If the six-bit reader is not covered, just shut lens detection off. No problem.

(Cosina) Voigtländer’s adapters has worked well for me. And, as have been note, some lenses won’t focus correctly without the cutout.

just realised that with my newly acquired Nikkor 28mm f3.5 LTM - I have 3 leica 28/90 adapters but unfortunately none of them have the cutout

Hi,

I only have original Leica adapters. The reason for it is that to me, the difference doesn't worth the risk of non using original ones. Please keep in mind that, in photography, precision is everything, and I've seen several cases of people complaining about sharpness issues (specially in the corners) due to lack of perfect parallelism between the mount and the film plane.

Personally I tried once a cheap Chinese adapter for mounting my Nikkor lenses into my A7 and the we (the salesman in the shop and me) had a bad time trying to remove it. It was about to stay stuck to the lens forever, so I went for the Novoflex.

Think on how much your lens or the mount in your camera worth, and if it worth to assume any risk for a few euros.

But that's just my opinion.

Stay safe,

Augusto

The cheap ones are cheap enough to experiment with making a cutout. If you are using a wide angle lens there should be enough depth of focus (focus not field) to cope with any slight inaccuracy in the manufacture.

I have a mixture of ones with cutouts, not all Leitz originals. The one at the bottom of the picture is nearly all cutout. I believe it is an early one intended for the 21mm f4 Super Angulon.

I just bought another Leitz screw to M adaptor. I really only bought it because I was intrigued by the fact that it is another almost all cutout version. The one I showed earlier is for 21 to 50mm lenses, which need the cutout to clear infinity catches,  but this one is for 90mm. The question is why it is almost all cutout when no screw 90mm lens has an infinity catch that needs any cutout at all?

Any ideas? Or is it just another strange variation?
