I am all excited to shoot my first airshow next month with my 70-200mm F4L (and Rebel).
The sun (if it's a sunny day) is situated directly behind us, with the airshow being directly in front (of course).
Will a circular polarizer make any diff in a situation like that?
Also, should the "axis" of the circular polarizer (usually marked with the white strip) be pointed vertically (either up or down).
I have to get a new cir. pol. to fit my 70-200mm F4L, any recommendations (but affordable). Also, how do you rotate the circ. pol with the lens hood attached?
Thanks in advance.
PS, I've used a circ polarizer before, but with my old G3, not with a lens of this nature yet.
