Re: [OM] 24mm and polariser

[NSURIT]

As I understand it, they polarize the light which is at a right angle, 
therefore you tend to get more polarization in the center of the picture when 
you 
have the polarizer set for maximum polarization. This is a very unscientific 
explanation & I'm sure other will do a better job.  Bottom line for me is to 
pay 
to the use of the polarizer when using a wide angle lens.  You will also 
probably want to use a polarizer with a thin mount.  Bill Barber
