By all I can see until now, I'm really not expecting to find good filters for the CGO3+, so I will have to get the least crappy one... Polar Pros are nowhere to be found.High-end optical glass for HD quality footage Excessively lightweight for zero-effect on gimbal Standard Day 4-Pack – includes UV, CPL, ND4 and ND8 filters Made for use with Typhoon H, Blade Chroma 4K, Typhoon Q500-4K, Typhoon CGO3 and Typhoon CGO3+ camera lens Life-time warranty UPC ...www.freewellgear.com
I have this set although not close to being a pro by any stretch of the imagination....so not sure if would be a good choice for you?
I am also ordering a lightweight lens hood compatible with the Freewell filters to try...what do you think?
They also make a hood for the std. Yuneec Filters.
The photos show the difference in using the hood and without the hood. Very easy to mount, see Instructions The hood is only compatible with the Feewell ND filters placed in behind the filter and in front of the lens.www.ebay.com
About the hood, I would get one only if I have problems with glare, since the CGO3+ has a very wide field of view and the hood could cause vignetting (this camera is very prone to it). Also, it's more weight added to the front of the camera and it might be bad for the motors.
