Review on 📷 Viltrox EF-EOS M Electronic AF Adapter: Seamless Auto Focus Lens Mount for Canon EF/EF-S to EOS-M Mirrorless Camera M1 M2 M3 M5 M6 M10 M50 M100 by Osoulo Sharp

Bought for my Canon M50, works exactly as advertised. The autofocus is fast and sharp. Vignetting is present but not critical. I did notice a small bubble or smudge on the back of the booster lens, but as far as I could tell it didn't affect the photos. Overall I am very satisfied with this product. The best part is the extra aperture you get from your lenses. It turns an F/4 lens into a 2.8/F lens while almost completely eliminating the crop factor. Image quality is a bit softer with the booster than without, but not that bad. You won't notice if you only use it for causal/social media. This becomes more apparent when you try to use it professionally.
