What would you like to see as a test?
Sharpness, FOV, robustness :)
We used the 8mm, 14mm, 24m and 35mm on a 7D and C300 yesterday. The lenses handled well. Smooth focus and smooth iris control. I think the colors rendered very nicely with a nice contrasty pop. Lenses themselves are fairly big and feel solid. I wouldnt treat them like Zeiss and not worry about tossing them around but I would do that with many Canon L's either. Images looked great in camera. Got home and hooked the C300 up to our 42 inch hdtv and was floored at how good the footage looked with no grading at all. If you treat them right I expect many people will be happy with them. We will happily be getting the 85 cine version when it comes out.
Thanks for your feedback! Team Branch
