  • Worked very well!
Length: EF-M2II
I was definitely impressed! I tested it on GH5 using the following lenses: 16-35mm Mk III, 24-70mm Mk II, 35 Mk II 1.4, 50 1.8 and 24-105mm Mk I and they all worked surprisedly well! My co-workers who are also professional video producers were also very impressed! That extra full stop of light is going to really come in handy in low light settings! Awesome value for the money! I plan to buy another for my B cam. Definitely recommend it! ... show more

  • Four Stars
Length: EF-M2II
This won't work with manual lenses. You need Canon lenses for this to work.

  • Worth the money
Length: EF-M2II
It’s real value for money and the delivery was faster than other product I’ve ordered here to South Africa. You won’t have auto focus with this but works like a dream on my bmpcc4k with the 50mm 1.4 giving me an f stop of 1 :)

  • Necesario Actulizar el firmware
Length: EF-M2II
Muy buena solución para poder utilizar objetivos Canon con la bmpcc 4k, la uso con el 50mm el 70-200 y el 28-135 sin embargo no tienee la función de enfoque con ninguno, solo el estabilizador del propio 28-135 funciona, fuera de eso es una opción excelente.

  • 3rd time, where's my charm?
Length: EF-M2II
*Updated* This is the second one I've gotten from Amazon and the 3rd I've tried. This one will not even manual focus below F5.6 on an F2.0 lens. Metabones works 100% of the time. Sorry VILTROX I tried. ------ Did not work with any manual lens. Gave me a 'Lens Attachment Failure' message with all my manual prime cinema lenses. No error with AF lenses but it froze the camera way too often to be reliable requiring the battery to be pulled to reset. When it wasn't freezing it caused erratic behavior with my Sigma lens. It would jump into focus zoom randomly in manual focus, and in autofocus and it would reset the aperture to a minimum whenever I half-pressed the shutter button. I really wanted this to work. I don't want to drop $700 on another Metabones. ... show more

  • Preliminary Review: Autofocus works but has some issues, very loose mounts, decent image quality
Length: EF-M2II
I haven’t tested exhaustively but felt it was important to note that this adapter is not an equivalent in image or build quality to the metabones versions. Adapters generally aren’t known for stellar mount rigidity, but this mount is unacceptably loose on my gh5 and gx85 with a sigma 35 f1.4 on both ef AND mft sides. Construction of contacts looks a bit dodgy as well, but the autofocus mostly works, and image quality is ok, al little glowy wide open, not as clean as the metabones. For the price however, I’d say it’s ok so far as it’s a unique value proposition, but I wouldn’t pay more than $220 for it and say that you get what you pay for. ... show more

  • Great!
Length: EF-M2II
Works perfectly out of the box. Very solid and sturdy, doesn't feel cheap which makes me happy I didn't pay the extra cash for a Metabones. I'll update if anything goes awry but so far so good.

  • works with the BMPCC 4k
Length: EF-M2II
Works well with tge BMPCC 4k. If you can’t get a solid focus, spin the glass element inside and it should help. There are videos on YouTube that show you the way. Much better value than the Metabones, especially till they come out with a specific product for the pocket cinema camera.
