Leica 35mm f/2 eight-element Summicron and Leica M240 – Candid Portraits – By Steven Bleistein

The first generation Leica Summicron 35mm f/2 eight-element lens with attached optics, often called goggles, were made for the Leica M3 to convert its .91x 50mm finder frame, the widest it has, to a 35mm one. It was only later that Leica offered the M2 with a .72x finder optimized for its 35mm frame that required no optics for 35mm lenses.

The first Leica I ever bought was the M3, with a Summicron 50mm f/2 lens. While I love the 50mm focal length, I quickly found myself wanting a 35mm lens for street photography. For the M3, because the widest finder frame is the 50mm one, if you want to use a 35mm lens without having to resort to an external finder, you have no choice other than the made-for-the-M3 Leica models with optics. So I acquired the Summicron 35mm f/2 with goggles.

People who are familiar these Leica 35mm lenses with optics, which in addition to the Summicron f/2 also include two versions of the Summilux f/1.4 as well as two Summaron lens versions of f/2.8 and f/3.5, know that these lenses with optics work fine on just about any other Leica M model. They choose the 50mm frame, including on the analog M2, M4, M5, M6, M7, M-A, MP, and even the digital M9 and M240. The only likely exception is the M10 because Leica, as a compromise for making the camera body thinner, extended the lens mount about two millimeters, compromising the accuracy of the goggles.

So why use a 35mm Leica lens with optics on any M body other than the M3? Well, if you wear glasses, like I do, you are unlikely to be able to view the entire 35mm frame in the finder all at once. The widest I can view is the 50mm frame on all other models, which is why I use the Summicron 35mm with optics on all Leica bodies I own, including the M240. Also, the first generation Summicron 35mm f/2 the lens is from Leica’s golden years, and is better built than any subsequent Leica Summicron 35mm. The focus is exceedingly smooth and tight, as is the aperture ring. The barrel is brass, and there are no plastic parts to be found.

The optics always draw gazes from people and comments about how cool my camera looks. You would think that all this metal and glass would weigh a ton, but in fact this Summicron 35mm is lighter than the current aspherical model, even with the optics!

Looking up the serial number, which you can do here, dates the production of my lens as 1963. Leica made these lenses both in Midland, Ontario in Canada and in Wetzlar, Germany. Mine happens to be Canadian made. Leica’s quality control in Canada at the time was exacting, and I can discern no difference between the German and Canadian made versions.

Despite being an old lens, the optical quality is excellent. You would be unable to distinguish the quality of an image produced with this lens compared to contemporary models. You might detect some fuzziness and falloff in the corners at f/2, but even then you would have to be counting pixels. And really, who ever views a photo and actually cares about sharpness in the corners? The lens excels in monochrome, for which it was likely optimized. Subtle tones and contrast are beautiful, but judge the results for yourself!

If you are interested in buying one of these lenses, you had better hurry up. They are becoming harder and harder to find, and I have noticed the prices have increased significantly during the last four years since I bought mine.

  1. Steven, very interesting to learn that the goggles are compatible with your M240. I wonder if Leica actually had this in mind when they launched their digital series, or it was simply the natural outcome of their using the same rangefinder module base?
    I appreciated your observation about the comments you get when out and about with the goggles attached. When I used to take out my “fully loaded” M3, that is f3.5/35 Summaron with googles and MC meter attached, that combo would certainly get quizzical looks both from the uninitiated and those in the know, the latter of whom would sometimes come and look more closely at it. I have the special ERC that Leitz made for the goggles equipped M3, which comprised of the same saddle with an enlarged nose section.

    1. The finder windows and lens mount on the M240 is the same as all of the M bodies that preceded it. So if the goggles work on every M since the M3, why not the M240? Leica made a change however with the M10. The lens mount bezel protrudes a millimeter or two from the body, which is different from all the other M bodies. That means the googles are further away from the finder windows. I have tested my Summicron with goggles on an M10 in the Leica store in Ginza. As far as I can tell, the frame is no longer accurate on the M10 when goggles are used. It’s unfortunate, but that was Leica’s compromise to make the M10 body thinner.

      1. Steven, you posed the question: “So if the goggles work on every M since the M3, why not the M240?” It’s a good question that anyone other than an M3 user would probably raise. Given that the optics of the finder were specific to the .9 magnification of the M3 finder, what’s it like viewing through with the smaller magnification finders of later M’s? Sure the lens will mount, but actually using it to view? I’m intrigued.

        1. Viewing is no problem. The lens chooses the 50mm frame, so it is like viewing 35mm at maybe .6x or so. That’s not such a big deal, and no different from say the Leica CL. Far better than viewing at .72x and not being able to see the whole frame—at least for me!

  2. There’s no need to apologize for your Canadian Summicron by assuring us of it’s quality compared to its German siblings. Every Summicron from this period, whether goggled or tabbed, began its life in Midland. They were all designed by the legendary Walter Mandler at his studio for computer aided, advanced optical design at ELC. The 35 Summicron V1-4 are about as Canadian as you can get, no matter where they were assembled.

    Great photo of the guy with the American flag T-shirt.

  3. I love you candid portraits. Nice job, indeed! This 8-element Type 1 35mm Summicron is an astonishing optic. I used one with the goggles with my M3 for about 20 years but sold it when I decided to retire the M3. You know the story: I should have kept it…..

      1. Thanks, and yes, I know the 8-element units are still available. I sold mine for about $1000, so I was very happy. In the meantime, I had bought on closeout sale one of the Type 4 35mm Summicrons, the last version before the aspherical 35. So I am all set for now. On a similar note, I bought a 35mm Super-Takumar for the Spotmatic, and must say, it is pretty amazing for a $45 lens!

  4. I have a glasses-equipped 35mm Summaron that I bought to use with an M3. But it does indeed work just fine on other Leicas, except the M10 where the extra mount extension throws off rangefinder focusing. (Zone focusing still works, of course.)

    When I was a kid my dad had an M2 with v1 35mm and “rigid” 50mm Summicrons. Digitizing his Kodachromes and b&w negatives a few years ago reminded me of how great those lenses were and still are. I have the 50mm and now use it on the M3 but at some point, for reasons I don’t remember, my dad sold or gave away the 35mm. I do remember handling and using it, though I didn’t appreciate at the time how well built the early ’60s Leitz lenses were. Precision optical machines.
