Customers like the aperture control of the lens. They say it widens the field of view, and gains f stop as they increase the aperture. They also appreciate the price point for such an awesome aperture on a prime lens. Customers also mention that it makes the focal length wider, and opens up a whole new range of lenses.

5.0 out of 5 stars Absolutely awesome + 1 f-stop!!!
Reviewed in the United States on August 14, 2019
So I got myself a Canon M50. Very similar to the Canon 77D I already owned features-wise, but significantly smaller and lighter. I was a little bummed that I needed to get all new glass because of the EF-M mount, but then it turns out that there’s adapters that let you use your EF and EF-S lenses on the EF-M mount, albeit with the same 1.6x crop factor as my 77D, both being crop-sensor cameras. I'd been watching M50 review videos on YouTube and in one of them someone mentioned the Viltrox EF-EOS M2 Lens Adapter. Honestly, it sounded too good to be true at first. So you’re telling me I get an adapter that will make my EF lenses look almost their actual focal length (about 1.1x instead of 1.6x) AND also gain a full f-stop for about 150 USD? Yeah, right… I kept watching reviews on the Viltrox adapter until curiosity finally got the best of me. I ended up buying one from Amazon, hoping for the best. First thing I did, I had to try my beloved nifty-fifty (EF 50mm f/1.8 STM lens). Using the Viltrox adapter it now looks like a 56-57 mm lens (50 * 1.6 * .071) which is not bad at all. But wait, when using the lens and adjusting the aperture on the camera, it didn’t stop at f/1.8 but rather all the way down to f/1.2! My lens, brand new, goes for 125 USD on Canon’s website. The 50mm f/1.2 also on Canon’s website goes for 1,349 USD. I’m getting the aperture of a 1,300 dollar lens for less than 300 dollars (lens + Viltrox adapter). Sure, it’s not quite the same but I’m very much a beginner/enthusiast, so it's more than enough for me right now. That’s an excellent price point for such an awesome aperture on a prime lens. That’s only talking about the one lens, though. Got any EF lenses sitting around? Pop them into this glorious thing right here and get almost full-frame images out of them with extra aperture. Couldn’t be happier with my purchase. Get this adapter NOW!
