I've been progressively shooting video with DSLRs more often these days. This weekend I was asked to shoot video of performances an arts festival/showcase. There were musicians, dancers and a choir all on stage under manageable, but uneven lighting. If the performer stayed put in one spot, it wasn't bad, but any movement was a mess. Trying to pan, zoom and keep focus locked (all manually of course) really requires 3 hands. I also didn't have an external monitor attached, so determining focus was rather hard to do. I went into it expecting it to be a chore to shoot, but it was worse than I expected and this was with a 1DX. As a result, I have lost all desire to shoot video with the DSLR unless it's a static subject. The zoom box during recording is a VERY useful feature because you can confirm focus. The gradual transition of setting changes (aperture/shutter/ISO) is also a great feature. I might try the full version of ML on my 5D2, but it's still going to be rough to pull off decent videos of moving subjects. I think I might give up on the DSLR platform for video and invest in a reasonably priced pro camcorder.
