Canon EF 20mm f/2.8 USM
The focal length of this prime lens from Canon is on the edge of ultra wide angle when used on a full frame sensor or the 35mm film it was originally designed for. Even on a cropped sensor, it provides a good angle of coverage. We take a look at how it performs.
Pros:
- Good build and finish
- Nice focal length on Full Frame cameras
- Silent and fast autofocus
- Good image quality
Cons:
- Not that useful on cropped sensors
- Stiff manual focus ring (on example tested
- Distortion worse than on modern designs (minor point
- Hood not included with lens

Reasonably sharp wide-angle lens. There is slight red-green fringing, similar to 15 mm fisheye. Purple fringing is absent. Strong vignetting at f2.8-f4, but this goes away at f8 and higher. Good centre sharpness, but the corners are a bit soft at f2.8, and this improves by f5.6.
Pros:
- reasonably sharp
- usm focus
- excellent build quality
- accepts 72 mm filters
Cons:
- vignetting
- some CA
- soft at f2.8

Canon EF 20mm f/2.8 USM Lens Review
The Canon EF 20mm f/2.8 USM Lens fits in a nice wide angle focal length space below the ultra-common 24-something and 28-something zoom lenses. There is a noticeable FOV (field of view) difference between 20mm and 24/28mm. People often look for a prime lens for their ultra wide angle needs.
