SJ1000 Action Camera - How to measure FOV?

post #1 of 4
Thread Starter 
Hello guys! I bought this camera and it works like a charm ,though it doesn't say how wide the FOV is.A video example here: Watch in 1080p (Youtube has ruined the quality,the camera has a simular to GoPro quality - compared to my friend's Hero 3 BE)

It has fish-eye effect and according to Wikipedia,fish-eye is common only above 100 degrees field of view.Any ideas how many degrees are my lenses because with this camera,they have a variety of lenses and only one manual.You can't be sure which one is yours.

look at the lenses and determine their 35mm equivalent. then find an FOV calculator to see how focal length translates to FOV.

generally in photo/video FOV isnt something people think about, usually its in terms of the focal length of the lens in terms of mm in relation to a full size 35mm sensor/frame

This table should help you out. Look through the 35mm column if you already converted it to 35mm.
