Viltrox EF-EOS M2 Auto Focus Lens Mount Adapter

The adaptor still work when the camara is off. Dry batery

I love my M50 but have always been annoyed by its lackluster low-light performance. The speed booster helps the M50 immensely when it comes to shooting in lower lighting. I use the regularly with my 85mm and have gotten some awesome shots with it. I hope you give this a try and have the same, if not better results that I've had.

Works well for my new canon m50. Autofocus works for my canon lenses. I wasn't willing to dish out nearly 300 for the canon version when this does the job just fine.

The product works great! Autofocus is just as fast and sharp. No issues. The benefits of using full-frame lenses are huge. It's great to utilize the processing power and megapixels of a "cheaper" camera to get full-frame-like results. And being able to get even more aperture out of lenses means photos can have better bokeh than if used on a full-frame body. This product is absolutely worth the price!

I was reluctant to purchase this item, but I really needed a wider field of view for my lenses. In reference to picture quality, there is a very small reduction but not enough to be noticed by someone who doesn't own and EF-M camera. The auto focus is amazing, even with my older EF glass. I wouldn't trust the tripod mount that is attached to this adapter. All in all a great buy and would buy again if it were to break.
