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.

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

Canon 20mm f/2.8 USM Review
This 20mm is very good optically, and has superb ergonomics for use with both 35mm and today's full-frame digital SLRs . Its mechanical quality is superior to most of Canon's lenses today, with a metal filter ring, metal hood mount and metal forebarrel.

Canon EF 20mm f/2.8 USM Lens Review
Canon EF 20mm f/2.8 USM is one of the oldest lenses in Canon's EF lineup, originally released in early 1992. And up until recently, this was the widest, non-fish-eye lens in Canon's arsenal (the company recently released an even wider lens - EF 14mm f/2.8L USM).

Canon EF 20mm f/2.8 USM review by Creyr Glas Lightworks
I shoot with it on a Canon 40D. I bought this lens for shooting nightclubs and bands, in locations I did not want to risk taking my 24-105L lens. I intended this to be a cheap purchase that I could use at F4 to F5.6 combined with a bracket mounted flash to shoot clubs and events.
Pros:
- fast focusing even in low light
- wide
- great colors
Cons:
- I occasionally really miss shots because of focus being off

Canon EF 20 mm f/2.8 USM
In the era of APS-C sensors a 20 mm instrument became an equivalent of a classic 35 mm lens. On the one hand a shorter focal length might suggest more problems with the image quality at the frame edge, especially when it comes to distortion and vignetting.
Pros:
- solid casing
- excellent resolution in the frame centre
- very well corrected astigmatism
- decently controlled coma
- silent
- quick and accurate autofocus
Cons:
- average image quality at the frame edge
- a bit too high chromatic aberration
- huge vignetting even on an APS-C sensor
- weak work against bright light

The Canon 20mm f/2.8 USM lens often catches a bad rap for being soft in the corners, having horrendous vignetting wide open, and being plagued with an overall lack of contrast. I'm here to tell you why absolutely none of that matters.

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
