Review of Auto Mamiya/Sekor 135mm F2.8 M42 Mount - My version, an eBay purchase (07 NOV 2013) is physically in good condition, has no scratches or blemishes to the exterior or optical elements. Aperture ring clicks smoothly, and no oil on blades. The focus ring is very stiff, which makes my lens cumbersome to operate, undoubtedly attributed to the age of the lens. Images are of a relatively pleasant bokeh. Aberrations easily controlled. Good contrast after with no adjustment out of the camera, sharp for landscape & nice portrait use.
This lens does not mount well with original Pentax M42 Screw Mount to K Mount Lens Adapter. I encountered lens wobble and issues with aperture stop down with several Pentax DSLR cameras. The problem is possibly an apparent narrow base Mamiya M42 mount.
Mounted to adapted mirrorless cameras the lens functions perfectly.
Updated 2 January 2024 after recent cleaning and regrease.

++ not very expensive, but somewhat very good  // bon maché, mais bon objectif
++ high contrast // haut contraste
++ fine color rendition // belle rendition des couleurs
++ very good sharpness // excellente netteté
optmal for portraits / idéal pour des portraits
Ps. there are a lot of Revuenon lenses in the market, nearly all 4/4-constructions of different manufacturers. / il y a une foulke des objectivs REVOUNON au marché, presque tous en 4/4 constrruction.
PHOTO-Quelle, Germany, had a lot of joint ventures like PORST. PHOTO-Quelle, en Allemagne d'Ouest, avait - comme FOTO-PORST - une foule de connections avec d'autre entreprises.
++ The best one is the shorter AUTO REVUENON MC in approx. same housing as images obove. Best results therewith when shooting macro pictures at f 8-11 and with macro ring and focal reducer. extremely sharp. // l'objectif AUTO REVUENON MC, combiné avec une bague macro - réducteur focale intégré - vous permet des macrophotos excellentes.
PS: There is one Revuenon 2.8/135 of plastic housing - it has less coating and therefore some flare, BUT 5/4 elements and extreme sharp maco close-ups. It has been made by ENNA or/and ISCO with the same optical design and same plastic housing, too. One PORST lens has probably the same origin. But these lenses are yery rare to get. // Il y existe un objectif AUTO REVEUNON = ISCO TELE WESTANAR = PORST AUTO = ENNA ENNALYT 2.8/135 en matière plastique avec 5/4 éléments, plus de flou, mais trés net pour proxiphotos - mais très rare à trouver.

| Pros: | SHARP, nice colors, good size | | Cons: | Some CA, needs a hood | |
I have this lens branded as 'ACCURA DIAMATIC', but it is surely the same.
For Single in March 2015 I revisited the focal length that I used for my very first Single in challenge, Single in March 2014. In 2014 I used the M135/3.5, but for 2015 I used a lens that I acquired via those elusive Craigslist deals you're always hearing about. ($50 for a Ricoh TLS 401, four lenses and accessories.)
The Accura Diamatic 135mm f/2.8 is an m42-mount lens with M->A setting. An observant follower on my Flickr noted that the lens is identical in appearance to the Revuenon-Special 135/2.8 and could be the same manufacture.
Physically, the lens is pretty lightweight! Lighter than any of my vintage zooms, for sure, although a bit heavier than the M135/3.5. Unlike the M135/3.5, there is no built-in hood, but I added a screw-on hood (55mm diameter). The construction is metal, solid and velvety. Although when I received this lens and its brethren it did not appear as if they had been carefully stored, there is no apparent damage to the body of the lens, or the glass. Focus is smooth and steady, glass is crystal clear, and the aperture ring is good. The stops for each aperture setting are VERY slight and it's easy to slide past one to the other, but I just learned to be very gentle with the adjustment.
The lens is m42 (screw mount), and therefore there is no communication with the camera for aperture. Adjusting the aperture manually always gave "real-time" visuals through the viewfinder; that is, the viewfinder darkens with every stop down, and the DOF is represented truly. It was VERY important for me to remember to open up the aperture for focusing, otherwise focusing was inaccurate. It might sound like more work, but I really enjoyed using using a lens like this. The direct feedback was awesome and I liked feeling so involved in creating the exposure, moreso even than K-mount M lenses.
This lens has the capability to be extremely sharp! Sometimes I would get the images back home on the computer and literally gasp when I saw the sharpness and detail the lens had rendered! The RAW files also responded very well to the sharpening slider in Lightroom. f/2.8 was a little too "glowy" and soft, but great for portraits (I took several of the dogs! ) F/5.6, 8, and 11 were all excellent, but I didn't really push beyond that, nor did I get very scientific during the month, as far as documenting the effect of different apertures on the exposure. As with any vintage 135mm lens that I know of, the MFD is disappointingly far away, at about 8-10 feet (but I used extension tubes to great effect!).
The bokeh the lens produces is very pleasant. I'm not a bokeh-fiend, though, and there are probably lenses that will give you "creamier" backgrounds, but the isolation is sufficient and satisfying.
There was some CA in high-contrast situations, but nothing worth writing home about, and easily corrected in Lightroom by ticking a box.
Colors are surprisingly bright and natural considering the age of the lens and the old coatings, and the contrast was just fine. I shoot all my images RAW, so there is always some compulsory contrast adjustment, but the colors didn't usually need more than a minor tweak.
All-in-all I love the lens. There is no critique I can make of its functionality and it creates spectacular images. Rendering/IQ was awesome across the board. It's been great, and this lens is a keeper. I'd probably even say I'm slightly more likely to grab the Accura Diamatic before the M135/3.5, so that's saying something!

| Pros: | Sharp, bokeh, quality optics | | Cons: | MFD at 2.5 m | |
I bought this lens in a cash converter it was really a good suprise i owned a pentacon 135 f2.8 and since then i rarely use the pentacon as i found that this lens produces virtually no CA. As mainly all the old non MC lens, the flare can be a bit of a problem but a hood solves this as it is a standard 55 mm screw mount for filters and hood.
I corrected only the white balance no sharpening applied.
