AF Functions & Adjustable Aperture: auto focusing function, increasing the lens 1 f-stop and the amount of light into the virtual background, better highlight the theme; adjust the aperture directly from camera to control the lens’ actual aperture. Material & Design: bayonets are made of metal with surface plating treatment, being durable and sturdy; inbuilt copper electronic contacts and IS function, making focus precise and clear, with 1/4" thread tripod foot at the bottom, etc. USB Firmware Upgrade: Equipped with USB interface, can realize software upgrade. Can perfect new functions of the lens mount adapter and fix bugs according to follow-up upgrades.

No complaints, I recommend to buy.

has some benefits When using the adaptor, there is no discernible loss of clarity. Seems to be a dependable source of information. It's possible to adjust the aperture by hand. Apologies, stairway. And in general, it would be quite pretty and smooth. Very promptly arrived. The Canon EF 24-105 L lens has a snag that makes it difficult to focus on distant objects at short ranges (between 5 and 7 meters) when zoomed all the way out. As if the adapter's focus length weren't sufficient. Everything…

I am not disappointed, the quality is satisfying.

The whole thing is really deserving, barring a few minor flaws. The following are some advantages: All three of those features (autofocus, aperture, and stub) are operational. The image quality seemed fine to me. More and more people are being exposed. Tripodal stance (for 4). The lens and the camera appear to be an extremely snug match. The rate of autofocus on gashane is fast enough to be considered good. data is shown in terms of the boost coefficient Told you so: The lens release lever…

Metabone Killer?

Anyone looking for a cheaper alternative to Metabons has come to the right place. Excellent quality aluminum alloy, so strong and durable. The mount wobbles a little (between the adapter and the lens), but performance is not affected.

Pros
  • Lens accessories
Cons
  • Long delivery time

As good as Metaboons in low light conditions

An easy to use static camera in very low light conditions. Replaced the Metabones Ultra with this and as far as I can tell the low light performance is identical. Using the same Canon 1.8 50 "Fifty-Fifty" gives a very sharp, brighter image than in real life.

Pros
  • Adapter and Converter
Cons
  • Secret

essential for accessories

I make films for a living and most of the money for these films comes from my own pocket. For people like me who aren't big Hollywood producers, this thing is essential to making an independent film. This allows any Canon EF mount lens to be used with non-Canon 4/3 cameras. This means you don't have to commit to buying overpriced and often inferior lenses for your chosen camera. Much cheaper than the accelerator, with the same results. You need it

Pros
  • Camera & Photo
Cons
  • Slightly torn

For the cost it can't be beat!

For what it's worth this adapter is great. With the exception of autofocus and image stabilization, all the lenses I've used with it have worked flawlessly. I'm using it on a BMPCC 4K, so autofocus and IS aren't supported by my EF lenses. For now I'm fine with that as I don't use autofocus and I shoot most of what I shoot from a tripod. I noticed that infinity focus was disabled, but I was able to fix that by rotating the glass element in the adapter. Now everything is sharp. I'm glad I bought…

Great cheap alternative to Metabone's

I bought these to fit Canon EF lenses to my LUMIX G7. So far I'm very happy with it. The build quality is almost all metal and feels solid. Autofocus, aperture control and EXIF work perfectly. Autofocus is a bit sluggish, but that's to be expected when fitting non-native glass to any system, and it's not a big deal for photos. Definitely a great and cheap alternative to Metabones. Image quality is good and fairly sharp around f/2 and above, softening everything below but still acceptable. It…
