picked up a set of ND filters from Best Buy, this is a link to the filters at Best Buy, and decided to put the C-GO3 on the steadygrip and put together a quick video of how they "performed". if you have any questions please let me know
Picked them up yesterday on sale for $29.00 at my local Best Buy. The ND 4 (lightest tint) has a solid build quality and is real glass too. Easier to install and remove than the OEM UV filter. I haven't tested them yet. ND filters are a valuable tool for my Sony Mirrorless cameras and still photography. Remember their purpose is to be able to slow down your shutter speed to 1/60th seconds for smoother video. I hope the same can be said about them on the CGO3.
