Review on 💡 Commlite CM-AEF-MFT Booster: Canon EF Lens to M4/3 Micro Four Thirds 0.71x Speed Booster Autofocus Adapter for Panasonic GH4, GH5, GH5S, GF6, GF1, GX1, GX7 & Olympus E-M5, E-M10, E-PL5 by Emmanuel Pictorial

I received this adapter last night. I was excited when I wanted to use my 18-35 Sigma Cinema lens on my BMPCC 4K. While the adapter attached my lens to my camera" there is a noticeable difference in sharpness. The speed enhancer is great as I get more light and a wider view out of my lenses, but unfortunately the image quality with this adapter isn't very good for me. Totally washed out blurry Lights.It was difficult even focus on the shot if I could at all.Unfortunately I will be returning it.I just think the glass element is not high quality enough for me personally.
