Viltrox EF-M2 II Auto Focus Lens Mount Adapter 0.71X Speed Booster for Canon EOS EF Lens to Micro Four Thirds (MTF, M4/3) Camera,with USB Update Port + CLOUDSFOTO Cleaning Cloth

Great. If you can’t afford a metabones. Get this. It’s perfect!

SORRY AND THANKS TO SPEND MY MONEY IN VAIN.

Works well for the price. Too expensive here on Amazon. I’d encourage you to search elsewhere for a better deal.

Softer then metabones. But with proper calibration, it gets the job done for the bmp4k.

Build quality is nice.I purchased the item(E bay US Seller) to used with my GH5 and Sigma 18-35mm. but,I had to returned the adaptor due to not hitting infinity focus right around 18mm to about 26mm with my GH5 and Viltrox EFM2 firmware upgrades to latest version.tried adjusting the Viltrox lens by turning the lens on EF mount side counter clockwise little at a time till in no longer turns and then opposite direction. both single AF and Manual focus and getting same results.I may give it another chance hoping to get a later batch copy (price is 1/3 the cost of Metabones)..

Works Perfectly W My Sigma Art 18-35 Lens For Canon

Can't get infinity focus. Tried turning lens clockwise as instructed by others with similar issue. No luck. Could only turn a little before it stopped.

perfect！
