Wide angle lens test

Picked up a Canon 10-22mm 3.5/4.5f. USM and doing side by side comparisons with the Tokina 11-16mm 2.8f. DX ii.

Results so far.
Tokina is heavier and better at low light but has a softer focus on the edges and also has a better color to the photo.
Canon is clear and crisp but has a slower aperture setting it also gives more zoom abilities and also can focus at a shorter distance.
Both lenses do a good job keeping lines somewhat normal for being a
ultra wide angle and are both very well made.
Both lenses are hovering around 600$
