Back in the real world scientists improve the following things when they design new sensors:-
- Image Processor
- Sensor Speed
- Sensor Resolution
- Sensor sensitivity (Quantum and Optical efficiency)
- Firmware
- Reducing the noise floor of the sensor
I don't know of any past attempts to make the sensor just a little bigger...
All said, there are 6 Olympus cameras with interesting Sensor/TruePic combinations:-
- EM5 (Even in 2022 this camera still offers a really unique IQ)
- EM10 III (The only 16MP OMD with the TruePic VIII)
- Pen-F (Could this be the reason why this 20MP has such a pleasing IQ)
- EM1X (Very unique camera)
- EM1 III (The TruePic IX processor is really important for this camera)
- OM-1 (Like the EM1 III, the OM-1 is unique and do not share its image processor)
When you study what we get with newer image processors and you see these 6 unique cameras then...
Have fun folks and enjoy your Oly cameras
