This was something that I have longed to do after plunging for the Canon XLH1 more than 2 years ago. A documentary was what I wanted and I needed a showreel to present to funding organisations for support. There are of course plenty more footage but for now, this seems to suffice.
The 5D Mark 2 however is a camera that I may be bringing out more though adapting it for wildlife filmmaking is a totally different thing altogether.
I will be shooting with both systems but the 5D Mark 2 will clearly win handsdown in lowlight situations.
