Stabilization at the top. Slight tendency to sometimes surexpo.

Tested with a 450D and 7D. The images are good view excellent. Stabilization is a bit brutal but bluffing in difficult conditions (low light and slow speeds). I underexposes systematically 1/3 or 1/2 f-stops of f-stops when any of the lighting is violent (sea, mountains). Solid construction, sun visor comes extra. Not much to complain at this price point. Go a little of vignetting wide open on some shots (must have the eye). Chromatic abberations are controlled. You can find better but bcp (too) expensive. Ex 70-200 f / 4 IS USM.
