I just picked up a Hoya 49mm circular polarizer. The question I pose to you
is this, I use Hoya Skylight 1B filters on my 55mm and 135mm lenses. I've
read that with wide angle lenses you shouldn't use additional filters with
the polarizer. But with the 55mm and upwards am I at risk of vignetting if I
use the skylight as well as the polarizer?

Firstly I put the polarizer right over the skylight, but then thought if I
put the skylight over the polarizer it would be good for protection mainly,
but also warming the image slightly since the polarizer loses a stop or
two..
Am I heading for bad news?
