Comments about B + W B + W 67mm #502 Color Graduated Filter - Dark Grey Neutral Density (ND):
I pretty much leave one of these filters on both of my L Glass lenses all the time, they do nothing more than improve my images. Makes it much easier to get exposers correct and have image quality not suffer. Also protects the lens itself from any damage.
Shot with B&W 502 filter
Also shot with B&E 502 filter

Comments about B + W B + W 67mm #502 Color Graduated Filter - Dark Grey Neutral Density (ND):
Unless item was a bad sample there was no discernable differnce in the density by eye or when mounted on a lens. It would be impossible to use. I have a graduated neutral density cokin filter which works well but I wanted a direct lens mount for my digital camera lens.
