Review on 💥 Enhance Your Canon EF Lens Performance with VILTROX EF-M2 Speed Booster Adapter - Auto Focus, 0.71x, M43 Camera Compatibility, USB Update Port by Chad Judex

I ordered this speedbooster together with GH5 and Sigma 18-35 f/1.8. The auto focus is poor, the image is soft, blurry and has color fringes throughout the image (as seen in the attachment) compared to a Metabones speed booster. I watched many youtube reviews before buying and most youtube users said it is very beautiful and sharp in the center of the picture. Apparently this is not the case that I have. I requested an exchange and the new one does the same. In a studio shooting test I did, there's not much of a difference between this and Metabones unless you zoom into the photo, but Vitrox smooths out skin detail noticeably, especially when viewed at a 1:1 ratio. Someone might like the optical smoothness of the adapter in video production (note the insane sharpness of the GH5). However, if you're interested in continuous photography, I think you should avoid this adapter.
