UPS just delivered my Panasonic 20mm f1.7 II. I had read the reviews and knew the Panasonic 20mm f1.7 autofocus wasn't fast, but I wasn't expecting it to be so unbearably slow. Some here have said that the 20mm f1.7 isn't that slow, and that it autofocuses about as fast as other m43 lenses when large focus adjustments are not needed, but they are wrong. This lens is useless for even slow moving subjects. I am definitely returning this lens.

I know the 20mm f1.7 has many fans, presumably folks who photograph static scenes. In my opinion, compared to the 17mm f1.8 and the 25mm f1.8, the 20mm f1.7 is a dog. Panasonic should be embarrassed for releasing this lens with barely-functional AF.

Slow AF on the 20/1.7? Absolutely. Except if you use it in ordinary AF-S in the range from 0.75 m to infinity and manage not to send it hunting. Fortunately, that exception accounts for more than 99 percent of my usage.

This is the kind of bad advice I was referring to. Even in these conditions I found the 20mm f1.7 unbearably slow.
