Well worth the money! If you need to run your lens wide open at the fastest aperture then you need this speed booster. The Viltrox will work well if you stop down, but wide open it was not clear and I thought that was normal until I tried this adapter. I can run my f/4 lens at f/2.8 through this lens with fantastic clarity.

It works great with my Sigma Art lenses! It’s truly optimized for the Pocket 4k. I have a previous version of the Metabones for my GH4 which I put on my Pocket 4K, and there’s a noticeable improvement in sharpness across the image. And it’s leagues above my Viltrox speed booster. Only con is you have to be careful when putting it on because the rear lens element takes up most of the space around the sensor inside the camera body. It would be easy to scratch the rear lens element if you aren’t careful to line it up when attaching it - much more so than any normal lens.
