COMMENTS: The EF-S 10-22 has the shortest focal length and widest zoom range of all the APS-C format "ultrawide" zooms. Image quality is good and distortion is remarkably low for such a wideangle lens The EF-S 10-22 uses three aspherical elements and one UD element to maximize image quality. It's also both internal focus and internal zoom, which means it does not change length when zoomed and the front element does not rotate during focusing. This is probably the best ultrawide zoom that you can get for an EOS APS-C DSLR. Definitely recommended.
