Video resolution for focusing
 

I see video finally has enough resolution to purge subjective focus opinions from production personel. As a former projectionist in film labs, screening prints of camera negative of multi-million dollar films in production, I can tell you that all my critical focusing and focus opinions were done by focusing on the film grain on the screen with binoculars. Likewise on location, you need a handbag/binocular devise that looks at a portion of the image electronically.
Sony isn't in the ballpark in this type of research/prototypes, right Sony?
Also, on location, always make an open angle of view of the monitor for the soundman as he usually has more insight on the production than anyone else.
