We recently added 3 more 4K cameras for a total of 4 cameras that have 4 times the resolution of HD. Though not yet widely utilized, 4K acquisition can bring great benefits to HD programming as well. Super sampling improves image quality and with better compression, the data storage requirements are becoming cheaper every day. Sony PMW-F55, PMW-F5, FDR-AX100, and A7Sii. See what the hype is all about.
