Magic Lantern for 5D Mark III 1.2.3

Ergo Zjeci

Recommended Posts

From Magic lantern forum a1ex:


It's out!


Not alpha, not beta, nor zeta, just a bleeding edge that happens to work for me. It might work for you or it might not.


(note that my standards are fairly high, so what I call bleeding edge, others may call semi-stable or







- bootflag issue solved!
- installation is really easy (simply unzip the files on the card, update firmware and you are ready to go)
- uninstallation is equally easy (update firmware and follow the instructions)




1) Format the card from the camera.
2) Make sure you are running Canon firmware 1.2.3.
3) Copy ML files on the card and run Firmware Update.

1) Run Firmware Update from your ML card.
2) Follow the instructions.

What's hot:
- bootflag issue solved! (p.s. some bloggers got it wrong, you still enable it in the camera, but you can disable it by uninstalling)
- installation is really easy (simply unzip the files on the card, update firmware and you are ready to go)
- uninstallation is equally easy (update firmware and follow the instructions)
- EosCard is now optional
- ML restores itself after formatting the card (man, that komputerbay card is fast!)
- you may install on any card combination you may think of.

What's not:
- unlike most firmware updates which fix minor things, this one changed a LOT, especially on the display side (for example, LiveView is now quad-buffered and most of the display registers were changed).
- watch out for corrupted frames (from my limited testing, I'm not fully convinced the issue is fully resolved on 1.2.3 => for serious video use, please consider staying on 1.1.3)
- fast zebras not working, but can be fixed
- no full-screen magic zoom (I never used it anyway, but was nice)
- no brightness/contrast/saturation adjutments (registers changed)
- HDMI issues (possibly worse than 113, didn't try yet)
- no documentation (yet).

For photo use (raw overlays, ETTR and so on) it should be just fine (that's how I use it).

Source code:
- the 5D3-123 branch in the main repository.
- feel free to merge it locally with unified or experimental branches to get a sneak peek for the future updates.
- I'll merge it to unified when I'll be confident it's at least as good as the 1.1.3 branch (based on your feedback).

Thanks to:
- chris_overseas for initial porting and testing
- horshack for advice about safely toggling the bootflag
- Audionut for early builds and support in the early porting thread
- marekk, pompeiisneaks, jpaana, rufustfirefly, sinubis and others for early feedback and small fixes
- mk11174 for getting the 700D port in sync in this one
- everyone else who volunteeres their time to make a great community project.

Final notes:
check nightly builds often and stay up to date! I'll do my best to make sure there are no critical issues in the nightly builds.
- there are quirks and bugs waiting to be fixed (please report them properly, with details on how to reproduce).
- grab the ARM toolchain and start hacking! (start with something easy or just tweak/fix whatever you find interesting).
If anything goes wrong, we don't pay for repairs. Use Magic Lantern at your own risk!

coming soon: a lot of stuff, including a real sensor upgrade, a C compiler that runs on your camera and other geeky stuff like this
