A fantastic focal length for APS-C cameras, the Canon EF-S 10-22mm stands as a 16-35mm equivalent in full frame terms. This lens’s ability to focus as close as 9 inches away allows you to fill the frame with small objects while creating elongated space behind the subject for impressive, dynamic compositions. Autofocus is snappy, and the lens overall is relatively lightweight for such a wide focal range. A perfect rental for a vacation since this wide angle allows for a wide field of view for getting more of the scene in the shot. Make sure you use this with cropped sensor Canon camera bodies like the Digital Rebel series as well as the Canon 20D, 30D, 40D, and 50D.
