To all those experienced photographers out there, I've got a question that has me stumped.
I picked up a Circular Polarized Filter the other day (Hoya) and have noticed a dramatic increase in the amount of time it takes for the camera to Autofocus. With the filter off I can usually autofocus on landscape photo within 1/2 a second with my lens. With the filter on, sometimes it takes 2 or 3 seconds to autofocus, other times it wont at all and I'm stuck trying to get it focused by giving the shutter button a push three or four times.
I've also noticed its wreaking havoc on my light meter which seems to jump all over the place now when the polarized filter is on. At first I though well maybe I picked up a linear polarized filter. So I checked, double checked, triple checked and quadruple checked the filter and as many times as I check, the info on the filter doest change. Its still stamped with PL-CIR on the side so I know I didnt grab the wrong one. The camera is a D90 and Im using an 18-105mm lens. Unfortunately I dont have any other lens to throw on the camera to see if its the body.
Is this normal?
