I know I probably wasn't using it the right way as some of the forum photos look awesome. I tried the dual-iso to extend dynamic range but really didn't have much luck. The focus peaking is pretty good (though not as fancy as Sony's A7 or Nex) If you are shooting video (especially with an external monitor) it is really nice having audio levels, focus peaking and any other histograms, waveforms, etc If you pull out the CF or SD card too quickly after opening the card door the battery will drain down quickly. The RAW video is darned impressive (and will need that "super new computer") but being able to adjust all frames in camera raw for exposure, noise removal, final color correction is awesome It has a fast white balance feature (just one touch on some cameras) that I have found useful for underwater photo / video If you shoot on a crop body you can have it display FF equivalent focal lengths I like that it preserves its installation when doing in-camera card reformatting Here are some various things I like and don't like: I know there are photography features but I tend to only use it for capturing video. I have Magic Lantern (ML) installed on my 5D2 and T3i and think it makes for a nice addition to the camera's firmware. Have people tried the stable version of the hack, did it do OK, and was it worth the effort? There have been a number of references to the Magic Lantern hack here on, but mostly "before" and little "after" experiences that I could find anyhow. I bought a super new computer (for which I am waiting) and the only intelligent justification for it is (as opposed to "I want it") that you are doing video.I actually found something that required video, as opposed to still photography (see picture below).I never planned on doing video, or I might have got the mark iii, but two things motivated me just recently I was partly motivated by the fact that I am thinking about trying to do some video with the 5Dii, and it seemed as though the hack has been helpful, according to testimonials on the Magic Lantern site. I have a Canon EOS 50D and a Canon EOS 5D mk ii, both of which are supported in the latest release version of the hack. I just downloaded and read through the literature available at Magic Lantern's site.
