Canon 24mm f/2.8 USM EF Lens
The 24mm is a nice extra-wide angle that isn't too extreme. The f2.8 aperture is moderately fast and will still offer a soft background. But the nicest elements to this lens are the extra features. Aspherical elements help eliminate softness at the edges. The autofocus is both quiet and fast, though full time manual focus is available too. The quiet autofocus makes this lens an excellent option for video as well as stills. Canon also included lens coatings and a seven blade aperture in this 9.9 ounce lens.
