Here is another article on how to improve or take your photography to the next level through gear choice. If you find yourself enjoying travel or street photography this lens is the one for you! It allows you to test the waters without hurting your pockets too much!
What I love about the Canon 20mm f/2.8 is that it gives me the convenience of getting the landscapes I usually want while I am traveling or the people portraits that I want while shooting different street photography shots.
If you're looking for another lens with a tighter crop or a smaller aperture check out the Canon 28mm f 1.8.
