So how slow to focus is the 20/1.7 anyway?
Mar 31, 2013

I've been following the debates on how slow the Panasonic 20mm f/1.7 lens is to focus. There are so many users complaining that there must be something to it.

In an effort to find out for myself, I took a sequence of 20 shots, alternating between two scenes some distance apart. Here:

First I shot 20 times with my 12-50 mm kit zoom at 20/4.0. This took 31 seconds. Then I did the same with the 20mm at the same aperture. This took 30 seconds.

So my first attempt failed to reproduce the problem.
