The new a7R II interchangeable lens camera features the world's first back-illuminated full-frame Exmor R CMOS sensor, which realizes high resolution (42.4 MP approx. effective megapixels), high sensitivity (expandable up to ISO 102400) and high speed AF response up to 40% faster than the original a7R.
Last year at IBC in Amsterdam, Sony announced the large sensor 4K FS7, which proved to be quite the hit for them. We've been taking large numbers of pre-orders from day one, and have delivery quite a few already, but the camera is still not as widely available as Sony and we would like due to the overwhelming demand from owner/operators, rental houses, and production companies eager to get into professional 4K acquisition for a very acceptable price.
