SIGMA fp firmware Ver.5.02 only (not the fp L, not other versions). Unofficial; RAM only, nothing is written to flash.
Install
- Camera: Menu → Custom → button settings → assign False Color to a button.
- Copy AutoRun.txt to the root of the SD card (only one AutoRun.txt on the card).
- Camera off, battery out 10 seconds, battery in, start. Wait for "fp ELZone/FC ready" the first time.
Use
- Short press: colours on / off. The legend comes back as you last left it (hidden after each start).
- Half-second hold: show or hide the legend while the colours are on (a hold while off turns on colours and legend).
- EL ZONE style shows the EL Zone legend; FALSE COLOR style the False Color legend. EL Zone labels beyond clipping are red: +4…+6 at ISO 100/200, +6 at ISO 400/3200 (from a published latitude chart, not yet measured per ISO).
Remove
Delete AutoRun.txt, battery out 10 seconds, start again. The power switch alone keeps the card in memory.

Getting started
From the project's README ("Install"):
- In the camera: Menu → Custom → button settings, assign False Color to a button.
- Download AutoRun.txt from the latest release and copy it to the root of the SD card. Keep only one AutoRun.txt on the card.
- Camera off, battery out for 10 seconds, battery in, start the camera. Wait for "fp ELZone/FC ready" on the screen the first time.
To remove it: delete AutoRun.txt from the card, take the battery out for 10 seconds and start again. The power switch alone keeps the card in memory (it is a warm restart), so always pull the battery when removing it or when switching to a different card.
