The HDL-20 was a single chip camera which was fine for most HD work. But the F30/31 now offered is substantially better at 3-chip, 2.3mps. Really lovely camera from Ikegami. Very useful digital zoom as well as the optical doubler on the Canon lens. Using the digital 2x with the optical 2x gives an acceptable 88x.
Gimbal system similar to SD - but different weights.
Been using the F30 for 2 years fault-free and now have 3 V12s with them fitted. We have the EASA mods for converting the SD V12s.
