Fotodiox offers strong support for mirrorless camera platforms with hundreds of options for mounting both modern and vintage lenses. Our adapters deliver infinity focus, manual aperture control, and a sturdy build for lasting quality. Compatible Sony E-mount Cameras (including but not limited to): a7/7R/7S, a7/7R/7S II, a7/7R/7S III, a7R IV, a9, a5000, a5100, a6000, a6100, a6300, a6400, a6500, a6600, NEX-3, NEX-5/5N/5R/5T, NEX-6, NEX-7, NEX-C3, NEX-F3, QX1. Please Note: This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc. ) will be disrupted. Set your camera to “Manual’ or ‘Aperture Priority’ for metering. If camera does not release be sure to enable ‘shoot without lens’ in camera settings. We state “infinity focus allowed” because our adapters are designed to be universal which can prevent some lenses from focusing to infinity at the infinity mark.

Finally I found an M42 adaptor that works for the Auto Yashinon 5cm F2. It closes down the pin for the aperture and allows infinity focusing.

Eigentlich hatte ich nur das Warehouse nach E Mount Artikel durchstöbert, da sah ich diesen Adapter zu einem lächerlich geringen Preis und ca 85 Prozent reduziert, sollte ich zuschlagen? So griff ich zu, hey ich hatte bisher mein helios 44 MKII auf einer Adapter Platte an einer A99 betrieben, mir fehlte rien zufällig ein M42 auf e Mount Adapter, so war das hier doch Schicksaldie Lieferzeit war OK, der Adapter noch gut verpackt ohne Kratzer etc, ich vermute davor hatte den jemand ohne Ahnung gekauft und dachte er habe AF, doch wie es nun mal ist sind M42 Linsen rein manuell zu bedienen da hier Motorenteile fehlen bzw Gewinde für einen Stangenantrieb. Der Adapter selbst ist superb verarbeitet, pures Metall, stabiles Gewinde und er sitzt perfekt auf einer Sony Alpha 7 Kamera. - mit einer guten Alpha und Fokus Peaking kann man perfekt manuell fokussieren und gute Ergebnisse erzielen für knapp über 6 EUR war der Kauf wirklich ein NO Brainer

Very good adapter, all metal. It does focus to infinity, no problem with my Spiratone 28mm 2.8 lens, I've heard there's issues with Helios lenses but easy to hack. Recommended

This M42 to E mount adapter works perfectly for my M42 lenses. I use them with my Helios 44-2 58mm f2 and Jupiter 11 135mm f4 lenses. The adapter works for Full Frame without any vignetting on my Sony A7S II full frame mirrorless camera. Solid build and fits snug. Would recommend because I have two of them :D

Qualità costruttiva degna di nota, completamente in alluminio quindi leggero, nessun gioco di accoppiamento su Sony A7R. Finiture e verniciatura di grande qualità.Consigliato.

J'ai acheté deux de la même marque pour M42 et aucun des deux est à la hauteur, le système de vises est fragile et peu précis.

Works as expected. Arrived quickly. Build and machining is quite up to par for the price. I have not had any issues attaching any of my m42 lenses. I currently use an SMC taKumar 35 3.5 and a mamiya sekor 55 1.8 on my Sony a7. Both lenses sit flush to the adapter and function as expected.Let's face it this is a piece of metal with threads on one end and another set of threads on the other that's pretty much it and it does what I'd like it to do not much else to say.

I attempt to find Fotodiox adapters whenever I can. They are very accurately machined, nicely finished and feature a button-type lens release instead of a simple tab. So far, I have adapted nine of the most highly-rated prime lenses to my ILCE Sony 7R and the results are spectacular. I say that, because I have been using medium format cameras since 1941 and the results I am getting from my Sony surpass the shots out of my Rolleis, Hasselblad and Mamiya medium format equipment. Not only is the shadow detail greater, but the smoothness in even tones, like the sky, exceed that taken with film cameras. If Fotodiox maintain their present high standards of quality control at their reasonable price points, they will dominate the market. I know something about marketing. I was the Ad Mgr for a Fortune 500 company when I was 28. Of course, I've been retired now for some 30 years. Keep up the good work!

The Fotodiox M42 adapter works will with Pentax and most other brand lenses that have a automatic diaphragm with a control pin on the back of the lens mount, with the Sony A7R. The adapter includes a seat on the inside that pushes the pin in so that the diaphragm is always closed to your set shooting aperture. The camera sets the correct exposure on using aperture preferred and following additional Sony instructions. You cannot use the "Manual/Auto" lever on the lens to open the diaphragm using this adapter. Also, you cannot use preset Zeiss Jena lenses that have a metal rim extending beyond the threaded part of the lens mount because they clash with the seat in the Fotodiox M42 to Sony E adapter.If you wish to use the Manual/Auto lever to open the diaphragm on your M42 lenses, you may do so by getting the Fotodiox Pentax K-mount to Sony E adapter and adding a Pentax M42 to K adapter. Then you may focus with the lens wide open and then move the Manual/Auto lever to close the lens to shooting aperture.Similarly, if you wish to shoot with older (1950's) preset Zeiss Jena lenses, use a Fotodiox Pentax K-mount to Sony E adapter and a Pentax M42 to K mount adapter ring, and these lenses will fit perfectly.Note added: Upon seeing comments on reflections from the rear of the front ring, I mitigated this problem by using a black Sharpie pen on the back of the chrome ring. If you wish, you could remove the chrome ring and use flat black primer paint. Finally, I have had no trouble using this adapter with nine different SMC and Super Multi-Coated Pentax lenses.

This works as stated, is well machined and cleanly finished. It is simply a tube of the correct length to allow for the use of Pentax screw mount lenses (M42 type lenses) on a Sony NEX e-mount camera. It clicks into place on the camera body smoothly and snugly. Then the M42 lenses screw into the adapter equally smoothly. However, you should check each time you shoot to make sure the lens is snug. It tends to loosen in use. This is especially true of long lenses. The problem is that the long lenses are heavy and you will, most likely, find yourself handling and carrying the camera by the lens if it is long (e.g. 135mm or 200mm etc.) to keep the weight off of the camera body lens flange. Additionally, you may find the older lenses are a bit stiff to focus if they have been out of use for a while (very likely!). As you focus, you may accidentally find yourself unscrewing the lens.

Tried this with the 50mm f1.4 S.M.C. Takumar from my old Spotmatic II, but it is not compatible. These later lenses have a tab in the mount that communicated the aperture to the setting to film camera bodies, and this tab contacts the inside of the adapter before the lens is fully screwed in. In fact, trying to install the adapter scraped some of the black paint from the tab.However, it does work with the older Super Takumar lenses, as these lack the aperture tab.To make the design compatible, the adapter must be modified to remove the flange that presses in the diaphragm pin. This is no problem as long as one switches the lens to "man".Problems are likely with any lens that has an enhanced variation of the M42 base. Other than that, it's a well made adapter.

This fits nicely on the NEX 5n, and seems well made. The M42 screw-mount can be rotated by loosening the three small set screws so that the lens might be oriented to one's liking, as I needed to do with an old Takumar 50mm f1.8. The combination works well and it is certainly fun to play with the old lenses again, using the 5n's excellent MF capabilities and the wonderful bokeh and shallow DOF inherent in the lens's design. I will probably get the equivalent Canon FD adapter as well. I believe that anyone with decent older MF lenses and a NEX ought to make the very small investment in one or more such adapters, it really is a lot of fun.
