MOST action cam use a 1/2.3" sensor. Combined with standard fisheye lens results in a FOV of about 120* horizontal / 170* diagonal.
However as the industry moves to smaller form factors like RunCam, Session, etc, a lot of cameras are moving toward using a smaller sensor size 1/3.2". Now obviously to achieve the same FOV they have a different focal length lens.
Does anyone has a calculator to see what focal lengths are using with 1/3.2" sensor size for a given FOV? Or what FOV we can expect taking a lens designed for a 1/2.3" sensor and mating it to the smaller sensor?
Thanks.
