  • 1Description

This Pro Lens Adapter from Fotodiox enables the use of your M42 lenses on Canon EF-mount DSLR cameras. It features a durable brass construction with stainless steel finish, a leaf spring ensures a secure connection between the lens and adapter, and its design also maintains infinity focus.

This manual adapter does not maintain automatic lens control between the camera and lens; aperture priority or manual shooting modes should be used, as well as stop-down metering for exposure control.

    FotodioX M42-EOS-PRO-V2 reviews

    Pro Lens Mount Adapter for M42 Lens to Canon EF-Mount Camera is rated 4.8 out of 5 by 33.
    Rated 4 out of 5 by from Good construction, great fit. Great fit when paired with a metabones speed booster. My only issue with this adaptor, is that it has nothing to shield the metal mount from making contact with the electronic contacts on the speed booster's EF mounting surface. This means that I have to use electric tape to cover the back end of the fotodiox adaptor or my GH4 will not be able to boot up, as doing so might short out the camera. With a bit of tape to keep the fotodiox from touching the electronic lens contacts everything works fine, but its a bit of a pain to maintain, and I imagine this would be an issue for other native EF cameras with electronic lens communication, like 5D & 1D, etc.

    Rated 4 out of 5 by from Quality manufacture at a great price. My first impression out of the box was the simplicity and quality of the manufacturing of this adapter. With this adapter I can now mount my old school Vivitar 400mm telephoto lens to my Canon EOS 70D DSLR camera. After attaching the lens I headed outside and took a few photos, then I downloaded them into Photo Shop Lightroom 6 and gave them a close look. I have to say I'm happy with the results. My one complaint; the add description states that the adapter will maintain infinity focus, I put this claim to the max test by attempting to photograph the 1st quarter moon. Setting the lens to infinity resulted in an image just short of focus and not correctable in Lightroom so I'm restricted to terrestrial photography. Had it not been for this discrepancy I would have given this product a 5 star rating. Over all I'm quite happy with the adapter.

    Rated 4 out of 5 by from Inexpensive way to use old screw lenses on EOS cameras The adaptor is very useful to use all my old M42 lenses and accessories on my EOS 6D MkII body. Focusing is manual and aperture setting is also manual. The only problem is that after removing the M42 lens, the adaptor is hard to be removed from the camera body, because there is not enough grip on the outer ring (protruding from the body) to turn counterclockwise the adaptor and remove it. I used the M42 lens pulling it hard towards outside to turn a little the adaptor (of course after pressing the locking button on the camera body). With a little practice you can overcome this small difficulty.

    Rated 4 out of 5 by from Works great with Helios 44-2 58mm bought two of these to go with two Helios 44-2 58mm primes. Both work as advertised. They click into place with a little effort, and feel firm. There is a tiny bit of jiggle in both lenses, and of the two lenses' back element sits too far into the camera body for the mirror to move by without getting caught, but I believe these to be defects in the lenses, not in the adapter. It doesn't have any digital communication, it's basically a threaded washer with an EF mount on one end and a hole for the lens mount pin, so if you're looking for focus checking, you'll need a different adapter.

    Rated 5 out of 5 by from Solid & well made I own 4 of these and also the Nikon lens to EF mount, as well as a couple other brands. These adaptors are solid, heavy-duty, accurately machined, and never a worry. For my work I find that computer chips on adapters are basically useless at best and might lock-up your camera body at worst. I have removed the chips from some adapters to improve them. If you are using some cool vintage lenses, you probably know how to add focal length to the EXIF data anyway, right?

    Rated 5 out of 5 by from Solid construction. Fits perfectly. Perfectly fits my old inherited Super Takumar 55mm for use with my Rebel T2i.

    Rated 5 out of 5 by from Easy and cheap Bought a cheapy fun manual 135mm f/2.8 lens made by Bushnell that used a m42 mount. This adapter fit between the lens and my EOS 30D without any trouble. Not tight or loose. Easy to unscrew and remove without any issues of having it getting stick. Well made aluminum adapter.

    Rated 5 out of 5 by from Great little gadget! I bought this to work with an old Helios-44m f2 58mm lens, that came with an old Zenit Camera. Works like a charm, it holds down the pin in the back of the lens so you can use all the fstops. It is a good quality build.
