No (no developments and probably can't do it)
No (50D can't do it)
No (I guess you're talking about compression)
thanks for the reply.. I wonder why 50D has problems in making a beep, being the camera able to do it while focusing.
as far as i understood right now the command that works in the others does not work for the 50D right?
regarding dual iso, i found a post from 1% dated yesterday that says he's trying to make it work on 50D:http://www.magiclantern.fm/forum/index.php?topic=3904.msg60409#msg60409
I guess you have more recent news if you say it's not possible
12/10 bit: it's compression as long as it cuts 2/4 bits of information, but it's still raw. there was a topic with many different attempts started but none was succesful. BMCC has 12 bit raw and it's more than enough! every way to shrink the size of the files without evident loss in quality is welcome, 8 minutes in 32GB is still a problem for longer productions.
