Last year at NAB, Panasonic revealed its concept for a 4K varicam camcorder. And what a concept it was, with a large sensor and a revolutionary Android-based user interface. It looked like a genuinely new and refreshing idea for the incoming era of 4K or Ultra High Definition
The conventional view is that cameras that allow you to work with multiple lenses are always better. Barry Braverman disagrees.
After seemingly years of being behind the curve with 4K, Panasonic announces a stunning new 4K Varicam system, including a Super 35mm sensor. This is a genuine cinema camera in the vein of an Alexa.
Most large-sensor cameras use a Bayer colour filter pattern to allow full colour images to be output - after "debayering". This entire process is now pretty routine but unfortunately what is also routine is the amount of light lost through the colour filter process.
