Hi Scott,
The camera does it for you. The ZX-5n's light meter doesn't know you've put
a filter on, it just measures the light making it to the meter and adjusts
Av and Tv accordingly. You may not have hurt much, depending on the film
(print film is more forgiving than slide film).

>Hi,
>I have a ZX-5N and was using a circular polarizer on a wide angle lens (28A)

>to increase up to a couple stops when using a circular polarizer. My

>the circular polarizer on the lens and the meter provided about two more
>stops vs. when the polarizer was off. I used the same scene to judge this.
>Later, I also did this with various sites at the show and did the same

>My question, long message to read to get to the question is this, do I have
