What’s the difference between
the 1/1.8 and the 1/2.3 lenses?
Both lenses are 4K
The 1/1.8 allow in more light.
The downside is that you cannot close the ‘GoPro’ lens cover and it’s more expensive.
The 1/2.3 lenses allow less light through.
The upside is that you can close the lens cover and it’s less expensive.
