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 David Gagnon

I recently got my hands on a Metabones ultra-fast accelerator and was considering using an additional Canon lens on another Micro Four Thirds camera, so I went with this one , hoping it would be that's as good as I've heard. Well maybe some? But it looks like quality control is a big issue for Viltrox. I filmed the rough scene with a 4k pocket film camera with an 18-35 Sigma Art lens. Metabones were sharp and clear. Viltrox was blurry and had chromatic aberrations. I went with f4 from f1.3 and the Viltrox looked a little better but the only reason I got this lens was to shoot at a high aperture. I tried adjusting the Viltrox by rotating the inner lens but that only made things worse. If you have time to send them back and get others you can get a good one that works fine. But if you don't have time to play around with this stuff, just grab the Metabones.
