"On my 5D, shooting at 16mm is pretty dang wide. The widest I’d usually go was with my 24mm f/1.4L II prime for any real production. With that in mind, I’d much rather shoot with the Cinema Camera in 12-bit RAW using the Sigma 8-16mm lens and not only get the focal width I need, but also have superior image quality and dynamic range that the DSLR cameras can’t touch with a 1-million foot pole. Oh, did I mention the dynamic range? Yeah, GOBS and GOBS of dynamic range." From Marco Solorio http://www.onerivermedia.com/blog/?p=677
