ZHONG YI OPTICS Mitakon Zhongyi Canon FD Mount Lens to Micro 4/3 Camera Turbo Mark II Adapter

It works as described. Fully functional speedbooster with no picture distortion not artifacts for impressive price

I really wanted this to work at 1/4 the price of a Metabones but, alas, it didn't fit. I tried, I tried again, I kept trying. IT's not the lens. It does have a warning saying it doesn't work for all lenses, and I guess this is one of them, but if you buy something to work for an FD, you expect it will without having to do any more research or tinkering. Bummer. Returning.

Just fix the stupid aperture pin and this thing would be great. Does flare a bit, but that's a desired effect for me.For those having issues: the lens aperture bar must be curved and snag the aperture stop-bar on the adapter as it twists on. Some FD lensed have a straight-shaped aperture bar that sticks up, and this will not snag during installation, requiring adding tape or some kind of expansion to snag this piece.

The adapter works well, I couldn’t figure out how to get aperture control with it because it was seemingly stuck open. But you have to put it on with a secret code and that’s really stupid, but ultimately I have aperture control again. For the price, it seems like a good deal, we will see how long but lasts.

SO SHARP. Crystal clear image with no artifacting... I'm in love.

Adapter does what it says but does not allow for the aperture to be changes and is stuck at full open.

Love the adapter. Using it on my Sony Nex-5. Typically fitted with a Canon FL 55mm f1.2 (which is what's used for the image I uploaded), and also a Canon FD 135mm f2.5, and sometimes a nFD 50mm f1.4. Perfect or near-perfect infinity focus.
