View Full Version : Using a Polarizer on a wide angle lens

For the 10-22mm lens, I know the skies will have a gradient look when using a polarize filter, will it have the same effect on the water with the gradient look?

What do you mean by "gradient look"?
Polarizers cut down on "polarized light" (light coming at an off-angle due to refections, haze and such). a polarizer has two main effects: first it cuts down on reflections from non-metallic surfaces, and that includes water. Second, it can boost saturation from some things, such as a blue sky, because the reflected light from "haze" gets cut down.

The polarising effect depends on how many degrees away from the sun the camera is looking at. The effect is greatest when the camera is pointing ninety degrees away. With a wide angle lens, the effect will be varied in different parts of the frame. It's generally not advisable to use a polariser on a wide angle lens.

What occurs with a CPL on wide angle lens is banding due to the different angles from the sun with a wide angle lens. There is a good chance of also getting some vignetting as well.

In answer to your question, yes it can.
However, usually water is not as smooth nor makes up as much of the image as an expanse of sky and so it is usually much less noticeable.
You can see it on this image for instance (was a blend, so no exif), but is was at 15mm with the 10-22 with CPL turned to minimize the water reflection (I got away with the sky being OK).
You probably wouldn't notice it if I didn't point it out.
