FotodioX M42-EOS-PRO-V2 Overview

  • 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 36.
    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 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 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 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 Excellent Lens Mount Adapter! Utilizing this adapter with M42 lenses allows shooting in multiple modes with the Canon EOS system, but keep in mind that autofocus is not possible with this configuration. Also, focus confirmation features available in Canon EF lenses are not possible to achieve using this adapter. There are some other adapters that are designed to activate focus confirmation, but if you enjoy manual focus as I do then this is the only adapter you need. I would absolutely recommend this lens adapter and B&H Photo to anyone looking to try classic lenses on a modern Canon camera. The quality of the construction of the adapter is superb. It is a beautifully constructed, brass and stainless steel coated ring, and it is very solid. It is noticeably heavier than aluminum adapters. The finish is very polished and detailed, with fine ridges that protrude just slightly over around the edge and center of the ring shaped adapter. Within the center of the adapter is a slightly embossed printing of Fotodiox Pro M42-EOS V 2. My package arrived two days early, and while the box in which it arrived seemed larger than necessary, the packaging was so secure that I would feel very comfortable with ordering a lens or more fragile gear, even a camera from B&H Photo. Mounting the adapter to the camera and lens was incredibly easy. I simply unscrewed the body cap from my EOS body Canon DSLR, screwed the adapter to the camera body, and screwed my classic Yashica 28mm f/2.8 lens to the adapter. The aperture PIN on the Yashica (and many other M42 lens) is pressed against a solid inner lip that protrudes from the center of the adapter, allowing for focusing in infinity for capturing full scenes and distant subjects. I was careful not to over-tighten, and was reassured by the slightly audible click of the EOS body's pin mount locking in place to the perfect-fitting slot cutout in the rim of the adapter. I've been really enjoying the experience shooting with this adapter on my Canon EOS 40D!

    Can I use this adapter to mount it on my Rokinon 12mm Canon EOS M, to my Canon EOS T5?
    Asked by: Anonymous
    You can't. The M42 mount (screw mount) is an old mount made in the 30s. What you are looking for is more for modern SLR/DSLR cameras.

    Will this allow focus to infinity? Thanks!
    Asked by: Zach T.
    Yes it will. I'm using an old Osawa 35-105 Macro MC lens on a Canon XS and it works fine. Bear in mind, the lens will be a completely manual operation,only the camera metering will work. Best results will be with camera set to Manual. The adapter is a small price to pay to have some fun with an old favorite lens that was otherwise used as a paper weight.Good Luck!
