General comment to all: Please donate for ml on their website, everybody who owns a 5d3 can spare at least $5 for the dev even if the download is free now!They have focus stacking, but not bracketing.
... should be trivial to implement, did you do a feature request on the new forum's section?

My standard comment on this: don't get your hopes up, though the 5d3 has the potential of running ml it even hasn't been decided which camera is targeted first, it might be the 650d. And even if the 5d3 is next, first the main dev Alex needs a 5d3 (donate!), and then I predict it'll be at least a year until a *stable* 5d3 release.
http://www.magiclantern.fm/newmodelsstatusMagic lantern is not yet available on the 5DIII, it is in progress and an early version should be available in October.
I didn't read that, where did you get this date from? And remember "early" version with firmware means feature-incomplete and you might very well brick your expensive 5d3 body - if the firmware goes into a loop, the cpu overheats in seconds and that's that.
Alex has already got enough funding and has purchased a 5D3 body, development will start soon.
I did all the initial testing with Alex since March when 5D3 was released and took that "Hello World" photo, I bricked my 5D3 numerous times and all successfully unbricked. The latest build I tested works really well considering it's done in just a few months, I believe it definately won't take a year from now for a stable 5D3 release.
