Canon released firmware v2.0.3 for the 7D recently. Go here to find it. It fixes some things broken by the 2.0 update.
The 2.0 firmware enables a bunch of new features. Here is the canon site explaining everything. My favorite options are the higher burst rate, higher max iso, and the manual audio levels.
I was about to put up a post about the new 7D firmware v2.0.3 from canon being released, but it was eclipsed by some amazong news. Over on the Magic Lantern site it seems that User g3gg0 has figured out the weird dual-digic configuration and has been able to run a hello world test on a 7d! It is not a fully developed release (not at all) but it is GREAT news, and an awesome step in the right direction.
UPDATE – Magic lantern just tweeted this video. It mainly shows the overlay window, but it also shows focus trapping. Even a tiny step is great, but this is a HUGE STEP!
I’ll DEFINITELY keep you updated as this develops. I donated to Magic lantern a few weeks ago, but I’m about to re-up! Here’s that link again, just in case a little $$ will get this first release out the door faster!
