Series 93 Polarising Filter

[SteveT]

Hi!

I am thinking of purchasing a polariser instead of a ND filter for my 40mm lens. I have read up a bit on the merits/demerits of using a Polariser - the uneven darkening to skies on very bright days in particular. My question to those in the know who have used a Polariser on a 40mm or very wide lens is is this problem universal at all times of the day and year. What conditions have to exist for this uneven cast on the film not to take place.

Thanks in advance for any advice that you can give me.

Steve

Yes I have used polarizer filters on 21mm, 24mm, 28mm and 35mm lenses. With 21mm and 24mm the corners may darken more than you want for some situations, but that is why most people use slrs so that they can see what they will get. Rangefinders are just so 1930's.

Polarizers darken skies best at right angles to the sun. They have little effect when pointed towards or away from the sun. At angles between these extremes, the effect is uneven from side to side.
