The Schneider Kreuznach 50mm f/2.8 Lens – Or Why I Love To Hate the Kodak Retina Ib

2200 1238 Chris Cushing

In the world of cameras and optics, few companies are as storied as Leica and Zeiss. Founded in 1846, Zeiss is one of the most enduring manufacturers of anything mechanical anywhere in the world. Leitz is nearly as old, and their Leica camera is as famous as any machine has any right to be. For most photographers, Voigtlander completes the pantheon of optics from the land of shnitzel. But there’s a fourth German optics company that gets far less attention, though it’s nearly as old and just as important.

Schneider-Kreuznach was formed in 1913, and with their impressive resumé, the brand is no lesser god. Unlike Leica, Schneider-Kreuznach has been almost exclusively a lens manufacturer, and the cameras these lenses have fitted to are legendary and varied; Hasselblads, Rolleis, Kodak digital cameras, and even LG smartphones. Schneider-Kreuznach lenses have gone to the moon, and they’ve won an Oscar for technical achievement.

To most photographic enthusiasts, the brand’s small-format lenses are relatively unknown and seldom seen. Indeed, until I purchased my 50mm Schneider-Kreuznach Edixa-Xenar, I’d never even seen one of their M42-mount lenses in person. This is surprising considering that Schneider-Kreuznach made a number of lenses in dozens of focal lengths in 35mm format. We should be virtually falling over Schneider-Kreuznach lenses. But we aren’t, and the brand’s small format lenses are relatively scarce on the secondhand market. That is, unless you look at Kodak Retinas.

The Retina

While Kodak is well-known for quality film, they’re not often remembered as a manufacturer of high-end cameras. Most of the company’s efforts, from the early days of the Brownie and the Pony and on to today’s Kodak branded digital point-and-shoots, have targeted the lower end of the consumer market. Kodak has not habitually chased customers who may have been considering Leica and Zeiss.

Kodak’s only in-house attempt to build a high quality camera ended badly. The Ektra was as expensive as it was unreliable (that means it was lots of both). But if the Ektra crashed and burned in Hindenburgian fashion, the brand’s only other high quality camera soared like a rocket. For three decades, the cameras in the Kodak Retina series produced by Nagel Camerawerks in Germany were quite possibly the best 35mm cameras to come from an American company. And this was in large part due to their excellent Schneider-Kreuznach lenses.

Kodak purchased Nagel Camerawerks in 1931, and commenced Retina production in 1934. Production was halted when some uppity Germans decided to turn most of Europe into a much worse place for everyone, and resumed at the end of the Second World War. In all of their many forms, Kodak Retinas remained in production until 1969.

All of the folding Retinas are quintessentially German. In much the same vein as a vintage Mercedes-Benz, they are beautifully made assemblages of precision engineering. But like a vintage Mercedes, the Retinas are defined almost as much by their compromises as their merits. For Mercedes, these compromises usually came in the form of an underpowered engine. For the Retina, the compromises amount to an array of bizarre ergonomic choices.

While my Retina Ib is my favorite camera to hold and fiddle with, its ergonomics make it tricky to shoot. My principal complaint comes from the toothed edge of the shutter speed selector. This arrangement tethers the aperture selector to the toothed wheel with a little arm on the bottom of the lens barrel. It’s designed so that the user can set a numeric exposure value and then decide if a higher or lower shutter speed is required while maintaining a constant EV.

In practice, it’s infuriating. This little piece of forward thinking means flipping the camera over every time you adjust the shutter speed for a new lighting condition. A one-stop movement of the shutter speed causes an equal and opposite one-stop movement of the aperture arm to maintain the EV. While this keeps the EV constant, in most situations, that’s not what we’re looking for in a manual camera.

If you’re shooting in consistent light, the Retina can be a real treat. If you tend to weave your way down city streets where the light between the buildings is constantly changing, the Retina will only induce rage. Wide latitude films can help minimize this issue, but even the most forgiving films can only take you so far.

This is a shame, because apart from this frequent annoyance, the camera does virtually everything else I like a camera to do. It’s small (smaller than a Canonet in fact), durable, and equipped with a fantastic lens. For years that Schneider-Kreuznach 50mm lens kept me coming back to the Retina despite its flaws.

Fortunately for me, Schneider-Kreuznach produced a nearly identical lens in M42 mount. Rather than tolerating the Retina’s quirks, shooters can easily enjoy this optic on anything from a Spotmatic to a Sony A7, and that is a very good thing.

The Edixa-Xenar 50mm f/2.8

The Edixa-Xenar lenses are deceptively uncomplicated. Both the Retina Ib’s lens and the M42 lens has four elements in three groups in a Tessar-type design. Both use roughly the same focusing design. Where the two differ is in the position of the shutter and the layout of the aperture.

Construction of the M42 mount lens is quite traditional, with a conventional five-bladed aperture actuated by a rear-mounted lever. The Retina lens has a Compur-Syncro leaf shutter mounted behind the removable front element, and a ten-bladed aperture diaphragm mounted aft of that. From what I’ve been able to find, the basic internal designs of the two lenses are very similar.

Though both are elderly (the Retina is from the mid-1950s and the M42 mount lens is from the mid-1960s) both seem to have unusually good coatings. I’ve never noticed any appreciable color fringing, and neither seems prone to flaring even in difficult lighting conditions. While the M42 lens has a built-in “hood” because the front element is set so far back, the Retina does not, but even without the built-in hood there’s nothing to worry about.

The M42 mount lens lacks the watch-like quality found on the Retina. While the focus and aperture rings are well damped, the overall feeling of the lens body is not as high quality as some contemporary lenses and the overall design feels a little clunky when compared to ergonomically superior Super Takumars. The aperture ring on the M42 lens is coupled to a moving DoF indicator, which is visible under a ring of clear plastic. It’s a little kitschy, and fifty years on this piece of plastic can make the cloudy window a bit tricky to see through.

These complaints are relatively minor considering what the lens is capable of in actual use. In-focus areas are almost punishingly sharp, and colors are rendered extremely vividly. If you’re looking for more punch out of color negative film, this lens might be an excellent choice. Blues in particular can become almost comically saturated, and yellows are abnormally punchy. For shooters who prefer a more desaturated look, this lens is sure to annoy.

Bokeh is extremely subjective, and I happen to like the effect produced by the Schneider shot wide open. Rather than creating a sea of blur and bokeh balls, the Schneider produces a very nuanced and textural effect in the out of focus areas. To my eyes this effect creates a lot of depth if used correctly, but quickly becomes distracting with a busy background.

Shots in the samples gallery were made with Kodak Ektar and Ilford HP5 Plus.


Because of its low speed the lens is ultimately less versatile than a similarly priced 50mm f/1.4 from Minolta, Nikon or Pentax. Despite that, its wonderful clarity and vivid color rendition might speak to some shooters. Because its look is so distinct, it’s hard to recommend this lens as a must-have for all shooters. I really enjoy it, and often find myself using it rather than one of the faster fifties in my collection, due solely to its characterful rendering.

Indeed, when I photographed the Kodak Retina for this review I picked up the Schneider and affixed it to my Fuji X series. Even on a crop sensor it can be a remarkably useful piece of glass.

In a sea of 50mm lenses that all do roughly the same thing and produce similar looking images, the Schneider stands out not only because it avoids many vintage-lens pitfalls (it doesn’t vignette, it’s sharp corner to corner, and it’s weirdly flare resistant) but most notably because it makes images with an incomparable look. Not many affordable 50mm lenses produce such distinctive and unique images, but this little Schneider does, and that must be worth something.

  • The coupled aperture and shutter speed never bothered me. The main irritation with the shutter to me was that if it was set to either the extreme fast or slow end, you would need to move it to give yourself more range and then make your selection. Still I love the Retina for all it’s weirdness (I have the IIIc) and the lens is just fantastic. I use mine now as a second cam to my Leica when I need another film.

    • It really depends where you are shooting, as I said. If the light stays pretty consistent it can be very handy. Where I tend to shoot(dark Northeast cities), it can be frustrating. In brighter locales it’s not so bad.

      And yes, the fact that the aperture arm hangs when going to the extremes of shutter speeds is also annoying.

  • Very nice article and pictures.

  • Last year I bought from a blogging buddy an essentially new Pentax Spotmatic F that he bought from a former Pentax employee. It appeared never to have been used, but my buddy had it CLA’d nonetheless and now it is in my hands. I bought it to enjoy the wonderful SMC Takumar glass but it does open the possibility of trying other M42 glass. This lens, with which I was not familiar, just zoomed to the top of the list!

    • Jim – Unfortunately these lenses can be hard to find, and seem to hover around $100. If you find one, definitely snap it up. There are also some really interesting 35mm lenses from S-K from the same period, which should give a similar look. Those are a little cheaper, and some have some wild quirks, like 14-blade apertures.

  • I love that when you review lenses like this one, you mainly show examples shot with it on film. Most others sites show images shot on digital, which is just not the same.

    On point – one reason that the colours may seem so saturated is because you are using Kodak Ektar film. That film can saturate a fog cloud at dusk!

    • Huss – I did actually do a semi scientific test of the saturation tendencies! I set my Fuji on a tripod and swapped back and forth between this lens and my 50mm f/1.4 Super Takumar. The Schneider is noticeably more saturated than the Super Tak on digital too. Using Ektar for the film shots didn’t help that tendency one bit.

  • First, STOP searching for anything good on the American eBay site. US Sellers are the worst – can’t spell, poor grammar, nasty, rude, everything seems to be from “estate sales” and more lies, uneducated, decent photos are a thing of the past – and sky-high prices for well-used junk. German lenses?,, THEY have the Schneider lenses! Having been stationed (US Army) next to the Schneider lens factory in Bad Kreuznach and been inside their factory (a HUGE honor!), I know of these lenses and how they are (still) made. Everything made in-house. They are still specialists in Space program optics. Aperture blade count over 6-8 has “wild quirks?” It’s cheaper to make better glass than 15+ blade apertures and easier to maintain. Schneider lenses are in almost EVERY 8×10, 4×5, 2 1/4 x 3 1/4, 120/220 folding &TLRs (Rollie, etc), on many 35mm cameras – M42 & tons of $$$$$$$ Nikon F-mounts), 8mm, 16mm, 35mm, 70mm movie, binoculars, enlargers, projectors, in space, and in every iPhone. Schneider did NOT copy anyone. Under-powered Mercs? They had superchargers and turbos in the ’20s. Hitler’s “car” was supercharged with over 800hp. 937. Reading these comments makes me think people have to get out more. Best and largest camera shops in the world? In the UK. Look real careful at vintage folding, box, Sears, Tower, Kodak cameras and S-K will be there – just in small letters.

  • Forgot to mention in previous Comments that almost all early German lenses were best used with AGFA color films of that time. Also, these S-K lenses with the German Deckel-bayonet mount (DKL) fit a wide variety of quality cameras (on Nikons and others with a DKL adapter). Kodak Retina Reflex has many S-K lenses available for it.
    Also, S-K has tons of 35mm lens in the Exact mount. Just sayin’

    • Daisy, I feel like you’re trying to tell us something about about US sellers,but I can’t put finger on in. I mean, could you be a little less vague? I am an ugly American, after all.

  • Hi there, nice lens and very good article. I think the shots are from Dundas and Hamilton, Ontario? It kind of looks like the escarpment. Keep up the great work, your website is top class.

  • I have both a Retina IIIS and a Retina Reflex IV. Both are superb cameras and can use all lenses interchangeably. The IIIS is the last of the rangefinders and has all the features of the early rangefinders. I have a complete set of Retina lenses. Look up the IIIS and the IV on the net to see their features. Incidently, I have use the Retina IV for nearly 55 yeats,

  • I love my Kodak Retina;s as I have about 6 of them and they are the most beautifil cameras every made as the craftmanship is amazing. Quirks they have none as far as i can see and the lens are pin sharp.

  • Vintage Optical Experimental Session September 14, 2018 at 6:36 pm

    There is a particular version of this lens extremly rare and expensive, with 15 blades, build like a tank in heavy silver metal, with m42 mount. I have tried it and its just outstandig quality.

  • You should try the Xenon 50mm 1.9, same version (m42, zebra), a very, very good and sharp lens !

  • Informative article … but two corrections.

    You said “Kodak’s only in-house attempt to build a high quality camera” was the Ektra. I beg to differ. The ’51-’58 Signet 35 was every bit a competitor to the finest German cameras, and built in Rochester. The attached Ektar 44mm f3.5 lens was simply superb, as were all Ektars, the coupled rangefinder accurate, and the camera was built like a tank. In fact, the US military was so enamored with it, thousands were supplied to the army and air force that were identical to the consumer versions, just painted black (for the air force) and olive (for the army).

    The last correction, I fully admit, is a tad pedantic, but worth mentioning nonetheless. The most notorious of those “uppity Germans” who interrupted Kodak Retina production was, in fact, an Austrian: Adolph Hitler. And these days, historians blame the war on the Nazis, who ranged in nationality – with some of the worst of them being French, Polish and Ukrainian, among others.

    But I digress. 🙂

  • Fantastic review.
    I love all these old lens, they are full of charm, there are many, reason why I am not a fan of new one’s especially if they are not made in Germany, Japan, I mean when this is poor cheap copy or only a cheap modern lens made in one particular country, of course I don’t buy. We have seen many reviews here about all these old lens, especially the Schneider Kreuznach, in my point of view they could be the best vintage lens. We cannot be wrong with this brand. Have a Schneider on our camera is the real path to have top original images. And of course, of course, if we use film, not digital camer, also if it is a very good Fuji, film will increase this great effect. This is the reason why, this kind of review is a treasure 😉

  • Fantastic lens

  • I am eagerly awaiting delivery of an SK Retina-Xenar 38mm f2.8 lens. I bought it from Bernd on Etsy (vintageglas) who removed it from a Kodak Instamatic 500 and 3D printed an m39 mount for it. He does good work. I’m particularly excited about this lens because it’s close to my favorite focal length, 40mm, and focuses down to about 2 feet.

  • Along the years, I acquired three of these beautiful cameras: Ia (013), Ia (015) and a Retinette 1b. While this last one has a Rodenstock Reomar lens, a very good lens in its own right, those little folders both sport S-K lenses, Retina Xenar. Really great shooters, if you ask me. Thank you for your good writing, enjoyable as always !
