This is my first try with video on EOS 7. I have seen great shots with EOS full format cameras, but I have got hold of EOS 7 witch has a 1,26x Crop factor compared with "fullformat" ref. EOS 5 Mk2. I found it difficult in action filming, real situations happening there and then. Working with tripod and "beatushoots" was OK. But I think that I can get some of the same look (Depth of field) on f.ex. Sony EX 3 camera on low stop using filter and may be negative gain. See this my tryout, a video in low sun and some fog by the seeside of Bosphorus.
