5 of the Best 20mm Lenses You Can Buy

When you get into wide and ultra-wide angle lenses, two of the most common focal lengths are 16mm and 24mm. There is a significant difference between those focal lengths, though, and something in between can be just the ticket, which is where the 20mm focal length comes in. With many options, you might wonder which is right for you. This fantastic video review features an experienced lens tester detailing five of the sharpest 20mm options you can purchase. 

Coming to you from Christopher Frost, this great video review details the five best 20mm lenses he has ever reviewed. I have always thought 20mm is an underrated focal length, as 16mm can be notably wide, but 24mm often leaves you looking for just a bit more coverage. What is also interesting is that 20mm is currently the widest focal length you can get with an f/1.4 aperture in a full frame lens, a title currently held by the Sigma 20mm f/1.4 DG HSM Art. This is particularly noteworthy for people like events and astrophotographers, who often employ wider focal length but for whom every bit of light is often at a premium. Check out the video above for the full rundown from Frost.
