Hi there,
Some confusion on circular versus linear polarizers... I know that the PL is supposed to ONLY be good for manual focus, and that for AF you need a C-PL. Then, I've also read that some cameras can't meter with a PL, and require a C-PL. Well, I didn't buy a C-PL, but just a regular PL when I bought into the Cokin P system this past weekend (B&H was out of the C-PL, and I wanted to take one with me to try out, as I was primarily buying it for my LF camera, I wasn't concerned at the time). I tried out the PL on my 28-70/4 yesterday, and noticed both the meter and the AF both appeared to work just fine. Now I'm completely baffled. Does anyone know if the metering will definatly be off without using the circular varient? And how did AF work correctly, then? -- http://www.infotainment.org "The destructive character is cheerful." - Walter Benjamin
