New and Improved Magic Lantern AJ5.0 Firmware for the Canon 5D Mark II Released

The legendary Magic Lantern firmware for the (itself legendary) Canon 5D Mark II hasn't been updated in a long while, probably owing to the fact that codec Tramm Hudson has a life. Also, since Canon added 24p and manual audio controls to the official firmware, there was less need for ML. Programmer AJ Newman has come to rescue with a new version of the firmware, entitled AJ5.0, which is a ground-up rewrite with a brand new interface that offers some great new features. Here's a look at what's new in this branch of the ML firmware:

Video is no longer available:

Some of the new or improved features include a completely re-done (and much-improved) menu system, false color exposure aid, customizable crop marks, five different histograms, "magic circles" (1:1 focus magnifiers), and CMOS temperature readout. As with all Magic Lantern versions, this is unsupported, at-your-own risk stuff. Note this only works on Canon firmware 2.0.4 -- if you're on a later version, you can downgrade to 2.0.4 with the file here. I don't currently have access to my 5D, so has anyone else out there used the AJ5.0 version yet?

I've used some recent versions of ML for the 550D, which has all these features, and totally rocks

peaking and focus assist (10x zoom in while recording), in particular, are hugely useful

As we posted in our article, this is one of those things that makes you wonder WHY Canon doesn't release some more improvements via Firmware Updates when there is so HUGE potential inside these cameras...

Just a reminder to Canon with a "short" List of Fixes & Improvements. Most of them are possible with the existing hardware, only software (firmware) updates are required:

Most users would even pay for improvements like those. Then why don't to take advantage of special non-free upgrades for advanced users?

If Magic Lantern was started by one man, and this special "AJ 5.0" version was mainly possible thanks to the efforts of one person (AJ), HOW MUCH could Canon give to customers? A LOT indeed.

Focusing aids, like many other features, are being requested since so long ago...

We hope Canon releases firmware updates, that are insignificant in costs compared to a whole new design (that also requires firmware coding). That would make these cameras even more versatile and useful. And would keep HIGH SALES for even longer time. That's what should also care Canon.

@5DMarkIITeam, If Canon made all those firmware updates, no-one would buy the 5D Mark III ! Never underestimate built-in obsolescence.

Also, they want people to buy their cinema eos series too. It's always about the scarcity when it comes to supply/demand :(

is this version of magic Lantern Aj 5.0 the same as Magic Lantern unified that was a beta version earlier in the year with the HDR n other added features?
