It installed and seems to be working but I cant give it an acid test until a bit later.  Noticed a new FW option to set the HDMI out FPS.  Defaults to auto vs 24 and 60i

Updated my camera with no issues. This video was captured via hdmi to a Blackmagic Intensity Pro capture card.

Personally I am waiting for the official release, but here is the md5sum from the file I pulled from the web

$ gpg --print-md md5 5D300121.FIR
5D300121.FIR: 3C AB 84 0C D3 D4 CF 17  5B 5B 4E 0E A5 14 EB A9

I am going to compare that to what Canon releases next week.

Can anyone with the firmware from canon confirm the checksum? Even if the canon release is different one will still be able to update to the canon release version overwriting this one, correct?

Pstodart: Did you figure out the audio recording? Video/audio to the card works as expected right?

[JPAZ]

Anyone have a chance to try the f8 autofocus capability?  Any change in the viewfinder focus points (red)?

Will take whatever the update gives us, but wondering if it is all we were expecting.

Yes you can force a reload, either through the EOS utility or through the camera firmware menu option.  You just need to drop the firmware in the root of the card (I used the SD card) and in the firmware menu it will ask to upgrade.

Funny how many people are perfectly fine loading up a firmware they found on someone's Dropbox account on their $3200 device. The "official" free update will be out literally in 4 days, and if something goes horribly wrong then, Canon can be held fully liable for it (unlike right now).

Normally I'd praise people's bravery for being the first to jump in to an new OS...but in this particular case, I don't think "brave" is the word that comes to mind.

Maybe otherwise screwed would be the term?  But some of us are a glutton for punishment.  I suppose it's no worse than dropping Magic Lantern on it.  I wouldn't have done it unless I had a spare to work with.

Well, people are certainly free to do with their gear what they want, however I am more than willing to wait four more days.  I sort of like to know where something going into my camera or computer has come from.  On the other hand, at least we get a preview on what improvements have been made and how effective they are (I'm wondering about the AF assist myself).

[Delish]

AF @ f8 feels snappy even at low light, it locks on reliably and with good speed, on my sleeping cats nose (with 1/50 and iso5000, canon 500mm f4 IS II and canon 2x III).

Tested AF-assist beam with my 580 EXII and it's back to the performance I was accustomed to in older models. IE: 5Dc, 5D2, 1Ds II...

No lag using Single point AF in decent low-light.

Actually, despite the "hack-ish" nature of Magic Lantern, I have to say that it is meticulously tested by probably far more people than official manufacturer's beta firmwares. The Magic Lantern community is so active and thorough that the risk of something going horribly wrong with one of their releases (not the nightly builds) is probably quite small.
