I finally took mine out for a spin. For the price, it's pretty incredible and very sharp. The only thing I'm not liking is the colors...at least it seems like in the same conditions, my Samyang renders colors VERY oddly compared to the Nikon 18-35g I have. It can be fixed without too much hassle in post, but is still a bit odd to me. Here's two shots from last weekend. Overall, will definitely be keeping this lens but will also definitely not be ditching any of my wide zooms.
Correct me if I'm wrong, but I believe every .3 is 1 stop. Hence 3.0 is 10 stops. The solid means it isn't graduated,so the density is constant throughout the filter
