I on the fence on this lense. My lens tint sheet say it is a 16% lens. What I'm wanting to know is how is the lens compared to other VR28 units. I have a VR28 black Iridium, VR28 Black IP, and have seen through an older VR28 lens. So is this lens about the same as a plain VR28 just a little darker. I just want some input before I jump on a frame with a lens I won't like.
