Seb Farges is a film director who uses the Panasonic GH2. And he particularly likes to use cheap third party lenses. The video on top has been made using the C-mount Canon 35mm 1.2 and Cine-NIKKOR 10mm 1.8 lenses. I like it a lot! One more new video made with the C-mount Canon and the Panasonic 14mm f/2.5 can be seen here: http://www.vimeo.com/21228832
