Caduceus v0.25 (beta)

⚠️ Unofficial, experimental firmware modification. Bugs will appear and flashing can brick your camera or lose data. The author accepts no responsibility for any damage. Provided "as is", without warranty (Apache License 2.0 §7–8). Without the EP7MOD folder the camera is almost stock; the restore file returns it fully to stock 1.1.

What's new

  • Lens vignette correction off per look. Picking a look turns the camera's lens shading correction off for that profile, for natural corners, without changing the menu setting. Extras sector 8 changes it (VigFix Off / VigFix Camera), and a look can keep the correction in the Control Panel.
  • Look NR now reaches photos. Extras sector 1 and a look's NR apply at each shot and follow a profile switch. v0.22-v0.24 wrote the movie setting by mistake, so if a past look changed your movie Noise Filter, set it again in the menu. Looks with NR Low or Off can look different at high ISO.
  • XP and 21:9 icons in the Super Control Panel option strip for Panorama and Wide.
  • Control Panel: a firmware selector, asked on first visit, makes card files for your version.
  • A BUNDLES.BIN saved with VigFix Off, or a LOOKS.BIN with a look that keeps correction, is rejected by v0.24 and older.
  • Firmware screen shows Caduceus: 0.25.

Reports wanted: vignette correction

The setting is confirmed in the firmware, but whether it changes the corners of a photo isn't yet. If you can, please test it and open an issue with your lens and the two photos: M mode on a tripod, an evenly lit plain wall, the lens's widest focal length and aperture, one photo on VigFix Off and one on VigFix Camera at the same exposure. Full steps: README.

Known issues

  • The Super Control Panel's current-value cell still shows the 4:3 icon when Panorama or Wide is selected. The setting and the photo are right.
  • NR is confirmed in each photo's recorded settings; a side-by-side pixel comparison is still to do.

Flashed and used on an E-P7.

E-M10 IV: testers wanted

E-M10 IV firmware is in development, but it hasn't run on a camera yet and no build is public. If you own one and are willing to test on it and report any issues, say so on issue #21. Please don't flash an E-P7 build on an E-M10 IV.

Install / update

No firmware files attached (OM's licence). Download the source zip below and double-click the launcher for your system (or python3 caduceus.py build --release v0.25). Copy DCOLYMP and EP7MOD/LOOKS.BIN to the card, keep your own EP7MOD/BUNDLES.BIN, then hold OK while switching on to flash. Guide: README › Install.

Only the E-P7 on firmware 1.1 is supported. If you enjoy it: buy me a coffee ☕
