I could use a linear polarizer with a wide angle lens and a hood
to avoid any vignetting. However, then I wouldn't be able to use
spot metering. Before I start spending money, I'd like to hear
comments on that option. I generally use my 28mm lens to
photograph buildings and other outdoor city scenes. How
limiting would the elimination of spot metering be for city photos?
I shoot with a PL almost exclusively with center weighted averaging
meter in auto mode. The PL seems to level differences enough that
it almost always come out right on, and then I always bracket. I
have a thin PL-Circ which was expensive ($40-50) but worth it to me.
If I only had a PL-Linear and were going to the trouble of spot
metering, I would use the linear polarizer by applying a filter
factor -- usually about 1.5 stops IIRC. Meter away, determine
exposure, open up 1.5 stops one way or another, then screw in your
PL-L and shoot.
A Worthy Experiment might be setting exposure comp dial to +1.5,
spot meter, and then screw in PL-L. I think that should work (but
have never tried it).
