## Customer Reviews

### ⭐ Countless Flaws
*by A***D on 10 February 2024*

I was excited to use the Viltrox EF-L Pro Adapter, but unfortunately I had to return it. Initially, it was difficult to work out how to use the electronic features of my lenses (the switch must be changed whilst the camera is off), but even when I got that working, I couldn't get it to appear on my computer to update the firmware (I tried 7 cables and 2 laptops), the Image Stabilisation and Aperture adjustments were INCREDIBLY loud, and the aperture indicator on my camera would change as I adjusted focus. Cannot rely on this for professional work, so as much as I would like a Positive Lock adapter, I have replaced it with the Sigma MC-21 instead.
