The image sensor size largely determines the image look and the price of a camera. Here we provide an overview of current sensor trends and future developments. The fifth part explores the sensor development at Panasonic and their light-sensitive OPF layer.
Panasonic = organic
Years ago, Panasonic decided to become more involved in the field of sensor development in the future, in order not to be left behind and to be too dependent on third-party manufacturers. While the light field technology announced by this manufacturer six or seven years ago, at least in terms of sensor chips, has not been heard for a long time, Panasonic can now report an interesting novelty: An organically structured, photoconductive layer has been used. organic photoconductive film “or” OPF “for short) has developed a new generation of sensors which, according to the manufacturer, can capture a significantly wider color spectrum and a dynamic range that is up to 100 times greater than the modern BSI CMOS camera sensors of the current generation.
Panasonic organically structured, photoconductive layer called OPF lies on the wiring of the sensor and is significantly more translucent than the top layer of conventional camera chips.

The highlight: the light-sensitive OPF layer lies on the wiring of the sensor and is around four to five times thinner and significantly more translucent than the top layer of conventional image converters. The new technology should promise a higher light yield, more dynamics and better noise behavior and capture the light at an angle of incidence of up to 60 degrees, while conventional CMOS sensors only work at 30 to 40 degrees. And according to Panasonic, the lower space requirement of the organic sensor has another advantage: The more compact design allows more flexibility in lens design. Another point makes organic sensor technology quite interesting for many videographers and cinema-makers: a different locking technology.
Panasonic’s OPF technology is intended to provide camera sensors with a better dynamic range.
