Not Panasonic and Olympus only but also TrueSense Imaging (ex-Kodak) is very busy on the Four Thirds sensor development front. EosHD reports that they just unveiled a new 4K Micro Four Thirds sized CMOS sensor.
These are the specs:
– 18.8mm x 14.1mm in size for a 4/3″ optical format
– global shutter for stills and a rolling shutter for video.
– 10bit 4K video at up to 120fps.
– Dynamic range is 72 db (11 stops) in rolling shutter mode but this drops to just 55 db in global shutter mode.
TrueSense imaging makes the sensor for Ikonoskop and Digital Bolex cameras. Don’t think Olympus or Panasonic will use the sensor. But I am pretty sure Panasonic will make a 4K FT sensor soon.
