Excellent lens. My new favourite.

Whenever I travel a lot by foot, this is the lens that I use the most regardless of lighting condition. Aside from all the comments on sharpness and being light, its IS is simply superb. I've used it handheld at shutter speeds of 1/5 and the IS saves the day.

This is another fantastic Canon prime I use for video. I have the 24mm L 1.4 ii , but i use this 2.8 specifically for video. I also have the 35mm F2 which I prefer over this do to better low-light and sharpness but this, over all if a great stabilized lens and fantastic for run-and-gun.
