Panasonic S9 Firmware 2.1: 4K60 in MP4 Lite, More Lens Fn Assignments

Panasonic's free firmware 2.1 for the LUMIX S9 adds 4K 60p/50p and Full HD 120p/100p/60p/50p to the MP4 (Lite) format, plus a longer list of Lens Fn button assignments and compatibility with LUMIX Flow app Ver.1.7.0. The S1RII, S1II, and S1IIE get separate updates tightening shutter-release lag and burst performance when shooting with an external flash. Bitrates for the new MP4 Lite modes aren't listed in Panasonic's changelog.
