Osmo Action 3 vs Insta360 ONE RS 4K (Read description) 

Here I compare DJI Osmo Action 3 vs Insta360 ONE RS 4K Boost Lens and how the sharpness is and overall difference in quality between those to great cameras.
This is not a scientific test and this is made for you to be able to check and compare for your own how the difference is.
Later on in video I do color correction and match both to look the same on screen.
If you are interested in seeing 6K from the Insta360, I will post a video just after this one with 6K almost straight out of camera, only color correction done in post and will upload it in ProRes for no loss in quality.
