## Description

VILTROX EF-NEX IV Electric-Lens Mount Adapter Ring

Review: Best accessory for Sony Camera with Canon Lens. - I was very scared about this Adapter whether it will work or not. Sigma MC-11 was 21k and this Viltrox was 7k. Instead of buying expensive lenses I decided to burn my money. I thought that in worst case , even if it won’t work , I will use it on manual mode. So I ordered this Viltrox adapter and immediately tried on 50mm f1.8. It worked with Autofocus in Contrast Detection mode as well as Phase Detection mode. I was very happy. Then i tried on Canon 85mm f1.8, Canon 10-18mm, Canon 25-105 F4. Autofocus worked as expected. Super happy. I saved lots of money without buying Sony Lenses. Buy this adapter if you want to use Canon lenses on Sony.

*by S***R on 2 January 2018*

I researched and decided to give viltrox NEX IV a go before i opt for Sigma. The adapter arrived on time.. First I tried to use a 50mm f/1.8 over it with A7s II and it was disappointing.. It never could focus.. Not once.. Then i put my EF 18-135mm and it nailed focus really fast and accurately more than 90% of the time and it was enough.. Then i updated the firmware and boom! 50mm started working too.. It wasn't as fast and accurate as the 18-135 and other lenses but that's more than what you can expect from a adapter at this price.. Really happy with it and would update the review if i faced any problem after more tests.
