Sensor size DJI FC300s

Could anyone tell we wich parameter to use in Context Capture sensor size

It is a Sony EXMOR 1/2.3” with effective pixels/photosites of 12.4 megapixels (total pixels are 12.76, but all do not get processed in jpeg compression - RAW, I do not know).

The sensor is 6.16mm wide and 4.62mm high.

The maximum created still image size is 4000 pixels wide by 3000 tall on both the Professional and the Advanced.

Also, the field of view is 94°, and it has a 20mm equivalent f2.8 fixed lens.

best regards,

Mark Bos
