This product, and all their products have changed the way I use my cameras. I can now use all my EF mount lenses with my Canon M50. The build quality is as good as Canon, or any other high end lens I've used. Fit was perfect and all electronics worked flawlessly (auto focus and stabilization). This now expands the lenses made for the M50 from 6 to all the EF lenses (which is many). The one thing to take note, before purchasing, is that only EF lenses work on this adapter and not EF-S mount lenses. I don't understand why they can't make a speed booster to allow the use of myEF and EF-S lenses though. The non speed booster version of this product (the one with no optics in it) that they make, allow me to use both types, why can't they make a speed booster that accepts all my EF and EF-S lenses like their cheaper adapter? Besides that one issue, I still recommend this product. It will open up your lens choices for your Canon M50 and is made of nothing but the best quality material. Read more
