Canon EF-S 18-135mm f/3.5-5.6 IS

18-135’s most attractive features are a wide (7.5x) focal range, a low price, a relatively small / small package, and a very good IS (Image Stabilization) implementation. I like that 18-135 focusing internally – and filters do not rotate when focusing. Image stabilization is a 18-135 IS feature that helps ensure the highest image quality possible. Canon rates this IS implementation at 4 stops. Specific testing with this lens and IS switched off indicated that I need shutter speeds of 1/25 at 18mm and 1/160 at 135mm for a good keeper rate.
