FotodioX M645-SNYE-PRO overview

  • 1Description

The Adapter for Mamiya 645 Lens to Sony NEX Mount Camera from FotodioX allows a Mamiya 645 lens to attach to a Sony NEX camera body. Adapting a larger format lens to a smaller format sensor provides optical as well as practical advantages. The smaller image field helps minimize the effects of lens distortion and aberration by using the center or "sweet spot" of the larger lens' image circle, thus providing edge-to-edge sharpness.

Although the lens will fit physically, automatic diaphragm, auto-focusing, or other electronic functions will not operate correctly while using this adapter. Manual or aperture priority mode must be used when this adapter is attached. Its all-metal design and polished surface provide smooth mounting and long lasting performance.

Built-In tripod mount
Stop-down metering

    Adapter for Mamiya 645 Lens to Sony NEX Mount Camera is rated 4.3 out of 5 by 10.
    Rated 5 out of 5 by from Beautiful new lens gains new life The product does exactly what it claims. I bought this item to use my Mamiya 645 lenses on my new Sony A7s. Wow. To see my 80mm lens back to life making beautiful images and video is really incredible to me. The photos it makes married with the A7s is magnificent. The photos are tack sharp because the 645 lens is only using its sweet spot. The blur is dreamy and having a real aperture ring is great. I can't say enough of how happy I am using these two products together.

    Rated 5 out of 5 by from Words perfectly. The quality is good with a solid metal construction. I use it with my Sony A7S, almost entirely for video and after some tests I feel the Mamiya glass is as sharp, if not sharper than my Canon L glass. I am thrilled that I am able to use some really good primes now. Its works perfectly. Zero complaints.

    Rated 5 out of 5 by from awesome adapter! This little $ dollar adapter allowed me to get out my old vintage Mamiya lens' and use them on my Sony a7r. I have no autofocus with this adapter but the a7r has great features to overcome that. It's well made and simple to use. even has a base for mounting the tripod on to it. Glad I found it.

    Rated 5 out of 5 by from Great way to use those old Mamiya 645 lens. I have played around with the adapter and two lens so far, have one more lens to try out. Easy to use on my Sony A6000 with focus peaking. $50 to get some use out of 3 old lens is a bargain. Adapter is well made and the lens lock in solid.

    Rated 5 out of 5 by from Great Deal!!!! I recently purchased a Sony A7ii and instead of buying new lenses for it I bought this adapter and am able to use all my Mamiya 645 Sekkor lenes and they work perfect with it and look fantastic, for only $50 bucks I added 5 lenses to my arsenal

    Rated 1 out of 5 by from Lens wobbles in mount All of my many Mamiya 645 lenses wobble in the mount. You can easily see the front of the lens move up an down or back and forth. Just the weight if the lens will cause the lens to hang down slightly for example. When measured at the interface between the adapter and the lens there is 0.010 inches of play when the lens is tilted up and down. Upon closer examination I found there are no leaf springs to retain the lens tightly against the adapter. Other more expensive Fotodiox adapters such as the Hasselblad to Fuji GFX do have these springs. If I had discovered this earlier I most certainly would have returned the adapter. I would have gladly have paid a little extra to have an adapter where the lens fits properly. Also be aware that the tripod mount is held to the adapter by two tiny screws passing through a very narrow stand off resulting in a relatively large amount of force being applied to those tiny screws . I would not trust it to hold a heavy lens where the weight is far ahead of the mount. Very disappointing overall. It's too bad because it appears well made on the surface.

    Rated 5 out of 5 by from Ma Ma Mamiya! Great adapter! Using it to fit a Mamiya 500mm f5.6 to a SONY A6000. No issues affixing to the camera or lens. Smooth workload for adapting all your Mamiya/Sekor c m645 lenses.
