ND8 is suitable for cloudy days and ND16 for sunny days
To remove Jello Caddx made a filter for Ratel and Turtle V2
This filter can be used on Turtle v2 (turbo eye---White print around the lens) ,Turtle V2(special lens) and Ratel(2.1mm lens)
The special lens doesn't work as well as turbo eye because the surface of the special lens is not flat.
