Polarizer question

[P. J. Alling]

The only problem with a linear polarizer is if the functioning of your 
camera depends on a semi-silvered mirror, (most do these days).  If the 
meter is behind it, (Pentax LX OM2/4 etc.), you'll get inaccurate meter 
readings.  If your autofocus sensors are behind it you'll get inaccurate 
or no auto focusing.
