Cumple. No es el de mejor calidad pero suficiente para fotos. Si haces vídeos, la montura tiene un poco de movimiento que se nota durante el foco.

Alte und in der Regel sehr hochwertige 645er-Mamiya-Sekor-Objektive lassen sich damit problemlos an der Sony a7-Reihe verwenden, was einem so manche zusätzliche Festbrennweite erspart - vorausgesetzt, man verzichtet auf Autofokus etc. Der Adapter ist stabil und präzise verarbeitet. Der Preis geht auch in Ordnung. Schön, dass ein Stativanschluss vorhanden ist. So wird das Bajonett der Kamera gerade bei Verwendung der schweren Mittelformat-Objektive entlastet. Allerdings kann es sein, dass dieser Stativanschluss bei Montage von Batteriehandgriffen etc. an der Kamera und gleichzeitiger Verwendung bestimmter Stativbefestigungsplatten (z.B. Manfrotto 120) blockiert wird. Als Abhilfe müsste der Stativfuß des Adapters länger oder nach vorne versetzt sein, was aber womöglich Nachteile für Handling, Kompaktheit und Stabilität hätte. Man kann nicht alles haben, also trotzdem fünf Sterne.

Un ottimo adattatore meccanico che consente di montare ottiche Mamiya 645 a fuoco manuale su corpi sony con innesto E.Gli innesti, sia lato ottica che corpo macchina, sono precisi, fluidi e privi di giochi una volta bloccati.L'anello adattatore presenta alla base un supporto ad innesto Arca Swiss che consente di non sollecitare la baionetta della Alpha 7 (notoriamente non robustissima) con le pesanti ottiche Mamiya. Questo supporto oltre alla slitta ad innesto rapido, offre una filettatura da 1/4" ed è eventualmente removibile svitando una brugola.L'ottica, una volta innestata sulla macchina, come ovvio funziona a fuoco manuale e in stop-down.Provato con Mamiya Sekor 35 f 3.5, 55 f 2.8 e 80 f 1.9 tutte MF. Le ottiche Mamiya AF sono prive di ghiera del diaframma, che è a comando elettronico e quindi non credo di possa gestire l'apertura del diaframma stesso. Io ho provato solo ottiche a fuoco manuale.

Good fit between adapter/camera and adapter/lens...don't notice any of the looseness issues that other reviewers have experienced. Works like it should, and even my heaviest Mamiya lens seems very secure. It would have been nice if the removable tripod foot (round) had been designed as a standard Arca-Swiss type, but I can easily machine something to fit.

Rock solid. I have no worries about my heavy Mamiya 80mm & 150mm lenses detaching prematurely. The solution is to use a 4-5" piece of wood and mount both the m645 adapter mount and camera tripod mount with (2) 1/4x20 bolts. A little awkward, but somewhat like holding a rifle in your left hand and shooting with your right.I have many products from Fotodiox and they are top notch.

Lens Mount worked just fine, but The mamiya lenses are difficult to focus. The highly regarded 45MM lens isn't nealy as sharp the Zeiss 55mm. Used in conjuction with the Macro Extender tubes? Now you're talking a 5 star experience. I just don't shoot any macro.

It fills sturdy with my Mamiya Sekkor 45, 80 (1.9), and 150. No leaks, no nothing.

I was uncertain as to the quality but was very pleased when it arrived. Meets the requirement better and for less than the competition.

I used this on my DSLR and my Mamiya 120mm. This is a heavy lens and therefore likely prone to too much front weight, especially on a NEX. The pin is easily pushed in and come off the camera mount. I was lucky I caught the camera and lens before it fell to the floor. I have other Mamiya lenses that are smaller and not as heavy as the 120mm, but they are still also prone to this happening. Get a solid connecting adapter before relying on a flimsy model like this. Be careful of this style adapter with a tiny spring, it will not hold and is easily bumped and falls off the camera.
