I tried a wide angle shot and got the black circles at the corners and then zoomed in a bit and they were gone. I would like to be able to use the polarizer lens for wide angle shots. I bought the lens on eBay and the seller said it was for a Nikkon coolpix 4500 digital. It's a Eitar 28mm circular polarizer lens. On the lens itself it says 28mm C-PL. Can anybody tell me if that is a Nikkon lens or if it should work on a Nikkon digital? If it were a Nikkon lens would it have their name on it? I should look up the ratings of Eitar lenses, shouldn't I. :idea: I got really gutsy and emailed the seller on eBay and he offered to refund my money if I send the lens back, even though I bought it back in April.
