Filter has a smudge on the INSIDE. What?
My latest complaint with this filter is that there is somehow a smudge on the inside glass. It even looks like a finger print. I noticed while getting ready to film a wedding, cleaning all of my glass.Cons:- These don't get dark enough to keep your aperture wide open on a sunny day for video. At least at f/2.8- Mine somehow has a fingerprint or some type of smudge on the inside.Pros:- No loss in sharpness- Durable/Heavy Duty- The ring stops at the max ND level.I like these filters, but I do wish they got a little darker.
