20/1.7 doesn't support AFF and AFC and can take a long time to focus in low light. 15/1.7 is better. And agree about 42.5/1.7 - must have.

I wanted to chime in and say that I also hadn't heard many good things about the 20mm 1,7, either.

Or, to be fair, I heard that it had a few issues, and that there were better options.

I want to chime in and say when I first used the 20mm in 2011 on the GH1, it took a long time to focus in low light and even not so low light or hunted. When I finally got to the GX7 everything changed. Same lens and no more hunting and the lens caught focus almost every time. Now it was slower because of the lens design-no internal focusing-but I would say a 98% improved performance. Same with the GM1. Panny really upped the game with CDAF
