Commlite CM-EF-EOS M Lens Adapter Review: Mount Any EF Canon Lens On Your M Camera!

I give a hands on review of the new Commlite CM-EF-EOS M adapter. This lens adapter from Commlite allows you to mount your Canon EF and EF-S lenses to you Canon M, mirrorless, camera. I tested the Canon 16-35 F4 and the Canon 24-70 2.8 II L. This adapter also allows all electronic information to pass through including: electronic control, aperture control, stabilization, EXIF info and more! For $43 bucks, its hard to pass this up as the Canon version costs around $199. As you will hear, this does add a bit of autofocus noise. But that being the only downside, it works perfectly otherwise.

If you are on a budget and don’t mind a few of the drawbacks, this works at least perfectly for stills. Check it out here:

Any suggestions for automated adapter for Nikon lenses to Sony

T. Frank says:

I’m using the Canon version since I was able to pick it up for $50 bundled with the Canon M100. Haven’t had any issues with it.

Chris Colón says:

2nd. Great stuff! Keep it up sir!

I understand you get lower light and better bokeh possibilities with the adapter/L lenses, but for this video at least, it doesn’t seem that there is any quality gained by using the adapter for video. Like you stated, I can certainly understand the use for photos, however. I wonder if the focusing noise is still present with efs lenses that have STM? If not, then it could be a great option for someone like me who has a few of those (efs 10-18 stm, 18-135).

Great review. I would like to hear the Canon to compare. However, this wouldn’t be a deal breaker for me. Actually it is now on my buy list. Thanks!
