I was pleased when I took this out of the packaging. It seemed decent enough. I attached it to my Sony camera and it went on smoothly. Then I added the Canon lens, which went on fine. Everything was okay, UNTIL I went to remove my lens. I couldn't get it OFF. PANIC! The unit came off the camera body okay - it was getting it to separate from the lens. I tried everything - and there was no support number for the manufacturer (wonder why). . .(could it be because of where it was made. . .?)
I purchased this adapter to use my old Minolta film lenses on my sony a7ii. Works perfect. Nice tight fit, no wobble anywhere even with a heavy 135 prime. Infinity focus works fine. Being able to use focus peaking makes using these lenses pretty easy.
You can't really screw up an M42 adapter, and this is no exception. Fairly well made, no obvious problems. As an adapter, it's excellent and I'd have no issues with buying it again. There's no light leakage that I've been able to determine. I didn't notice any reflections or other issues, though it'd have been nice if the interior was covered in a felt-like covering like I've seen on some other (non-M42) adapters.
The Fotasy Exakta to Sony e mount adapter rates 3 stars. The good thing is that the Sony e-mount sides of the adapters fit well. The not-so-good things are two problems with the Exakta side. First, on two of the adapters, end of the spring protruded through the hole in the catch lever and contacted the rear of of the lens or Exakta bayonet extension tube. Thus, it did not fit. Second, on all five of the adapters I tried, the flanges on the rear of the lens bayonet collided with the flanges of the Fotasy adapter. Therefore, I used a cheap "aftermarket" exakta bayonet extension tube and torque to force it open. About 15 to 20 turns were required to fix it (Do not do this procedure with a good lens!!!), plus I removed any metal bits released. Once this was done, the adapters worked. Finally, on the good side, Fotasy replaced two adapters that did not work. My recommendation is that Fotasy refine its production machining so that this additional effort is not required to make them work. I suggest that the new batches be tested and labeled as improved.
I'm going to preface this by saying I was going to return this item. I'm using a Sony A7M2 with a vintage Zeiss 135mm f3.5 lens. I noticed when I screwed the lens to the mount that their was a small gap (under a mm). I let that slide but I was finding that I had Blurry pictures. Yes, I know it is a MF Lens, but in preview it looked great. Images were still blurry. After some research and getting my head out of my A$$, I realized I was using a 1/30 or 1/60 shutter speed. With stabalized lenses, this is fine. But with this lens I needed 1/100 or higher. After the change the Pictures were tack sharp. So this does exactly what I needed. I'm using a 50 year old lens on a 3 month old camera. FYI: In my research I figured out the focal plane for my lens and this Adapter is within .5 mm of the M42 focal plane recommendations. So it is a great adapter at a great price. So buy one of these and start buying some great old vintage lenses!!
Does the job well
Excelente adaptador, se conecta firmemente tanto a la cámara como al lente, cuenta con un swich que al ser girado habilita la posibilidad de cambiar la apertura del diafragma de manera manual, el adaptador no tinen ningun elemento dentro por lo que la imagen pasa con claridad directo del lente a sensor.
I own a bunch of Nikkor D lenses. I have shifted to Sony mirrorless an year ago after 11 years of being Nikon user. D lenses being old, don’t have resell value but are optically outstanding. Also they have aperture Ring, so operating them fully manually with this adapter isn’t an issue.
Great little adapter that seems to fit perfectly on my e-mount camera. I am not sure if there is light-leak, but the images look great so far!
It works really well with my Nikon lenses. Both sides fits really well (not too tight, not too loose). I was worried about fitting on the A7II e-mount but it fits really well.
Don’t buy it. Had problems getting the lens to connect and come off. Blurry too.
Me sirvió muy bien para poder utilizar algunos lentes antiguos de mi Minolta MD.
Va perfecto en mi A7RII para un par de lentes Minolta Rokkor, esta versión queda bien sujeto al lente sin ningún juego, aunque dice que es solo para la serie a7 lo monte sobre una Nex-3N y funciona muy bien.
Funciono muy bien con el Rokinon 14mm F/2.8 manual y también en el cuerpo de una Sony A7 no hay juego con el adaptador y la montura, quede perfectamente y los materiales se ven de buena calidad.
Justo a tiempo, Le queda Perfecto a mi Sony a7
Perfect adapter for a manual focus lens. It does its job well.
