The Sony F-23 is a 2/3" chip camera but it has 3 Chips that are stacked just like the layers of film emulsion. Some people would argue that the F-23 puts out better images than the F-35.
The Sony F-35 has a 35mm sized sensor, and a PL Mount ( one not 3 like the F-23) which enables one to use 35mm film lenses like Arri Master Primes, or Cooke S4's or Arri Ultra Primes or Angenieux Optimo Zooms.
The Sony F-23 uses B-4 mount lenses like Ziess Digi Primes.
Both of these cameras record in 4:4:4 and can record to a Sony SR1 Deck onto HDCAM SR.
