M and R summicron

[darkosaric]

I am wondering: are summicron 50mm on M mount and on R mount optically same?

I know that those are two completely different approach (rangefinder and SLR) – I just want to know – if I buy cheaper R body and lens – will I get same effect (bokeh, specific leica look, same sharpness, and all rest...) as in M combination? I see that people on internet are glorifying M lenses, but R lenses not so much.

regards,

They aren't the same, that's why M series cameras and lenses are so desirable. I do use a 50mm Summicron on an M3 and it's an outstanding lens.

Can't comment about the R series lenses.

Both lenses have gone through many changes. You need the book 'Leica Lens Compendium' by Erwin Puts

I was afraid of this answer

I saw lots of great photos with summicron M mount - they have some atmosphere that is special, don't know to put it in words exactly what it is...

I am looking for summicron 50mm ... and first I was thinking to buy screw mount and put it on my zorki4. But I don't like shoot with zorki, it is not fun, doesn't feel right.

Then I was thinking that I will get same result with R mount... but on the end only solution will be some bessa or M leica. There is no workaround for this

The 90mm lenses (of more or less the same generation) are often optically the same in M and R versions.

The 50mm lenses could be (though in many old cameras 58mm was the classic border for having to use retrofocus designs). I have no 50mm in either.

The 35mm lenses definitely are not, and I like my 35mm R Summicron much better than the M one (strangely enough).

Generally speaking, you'll definitely get the look you want with the R system (the caveat of choosing wisely goes for any system).

See the links to "Technical Data" and "Know How" on this page http://en.leica-camera.com/photography/r_system/lenses/3802.html These lead to .pdf files, the first of which is Leica's technical data on the 50 and 60 mm lenses for the R system. The second is Erwin Puts' write up on the same lenses. It contains the following statement:

The current [50mm] Summicron-R is almost identical in optical con-
struction with its counterpart in the M-system.

I've shot R's for over 30 years, 24mm f:2.8, 50mm f:2, 100mm f:4 macro, and 180mm f:4, on two bodies. I've also shot with M lenses for over 25 years. Leica strives for a similar overall "family" character with all their lenses, but allows for different balances of characteristics so that each lens has it's own particular strengths. These design goals are clearly stated in their write-ups on the lenses.

The longer the focal length, the more similar that they are. Leica takes advantage of the short registration distance of the M-mount on all of the wider lenses. Anything from 35mm and wider is definitely to the advantage of the M-mount. Although, I have found that the 28mm Elmarit-R is a great lens.

There are several versions of course. Overal the 50's are very much the same as are the 90, the 135's and to some extent also the 35's. There are differences but they are small and more depending on your choice of film and style of shooting. In some cases the lenses are exactly the same as is the case with the 90 apo and the 135/2.8.
