Tim that was great a macro video, I am looking forward to next year to incorporate some macro video whilst out taking stills of the Butterflies, insects and Dragonflies, that will be with the trusty Sigma 150mm f2.8 in the first place, last night I put the kenko 1.4 between the 7d and the Sigma and that seems to work very well, a bit more magnification. I have only taken 2 videos so far, but it seems to me that manual is the way to go, to be able to set up your shutter speed that has a big baring on your video shots, well thats what I have learnt and read so far, keeping the shutter speed between 1/30 to 1/125 the slower the shutter speed the smoother the movement will be. My only gripe is no AF whilst videoing like most camcorders, but you can use manual focus, I find MF a bit harder to do when looking at the liveview, but everything comes with practice.
