Third Party Manufacturers / Re: Sony A7S 12.2 MP 4K video camera announced. Is it good for stills photographer?« on: April 24, 2014, 05:20:30 PM »
That sounds great on paper, but to me it seems more like a one -up on the competition, with little practical benefit. An example –4 EV is 1/15 s, f/2.8, ISO 102400. When you get to light levels that low, even if autofocus works the resulting image quality is not going to be very good, if even usable.
From the video above... even 1/50 s, F/2.8, ISO 409,600 in extremely low light looks usable. Granted that the colors don't pop like they would in a properly lit scene, but it looks like this new sensor resolves color information (at low light levels) better than the human eye.
I'd love to see this sensor in a body that natively accepts Canon Lenses... as I like working with natural light.
(Note - I've used Canon exclusively since 1984, my first camera was a T70, my second a T90 in 1987, and I've used Canon ever since... for both still and video work.)
