Olympus 17/1.8 review

My copy of the 20 f1.7, which I got with the GF1 when it came out, hunts excessively in anything but good light, and I've noticed that the E-M5 turns on more slowly with it, waiting for it to be ready, than with other lenses such as the 12mm and the 45mm. If the 17 f1.8 is even nearly as good as the 20 optically, I'll take it just to get reasonable AF performance at that focal length.
