Some success :-) There is a "cf_extend_iso" hidden custom function. This enables ISO3200 to apear in the system menu. Some bugs with it. It doesent appear always. In a few days I will post the code and the bin file, when it's stable.
Great work!
ISO3200 in menu, spot-metering in menu and its mostly perfect! Thank you!
- okay, more frames per second, or an Auto-ISO-function would be great -
but...
