Linear Polarizer Lens
Should I get a linear or circular polarizing lens for my Canon 20D DSLR?
I am planning on buying a polarizing filter to go with my zoom lens with my Canon 20D DSLR.
When shooting:
- I use autofocus most of the time
- I adjust the metering manually sometimes (trying to do it more often now)
I am not sure if I should buy a linear or circular polarizer.
Any advice?
Buy a circular polarizer. Do NOT waste your money on a cheap, no-name filter. Buy quality - Heliopan, Tiffen, B+W, Hoya, Singh-Ray.

DIY Polarization Filter from 3D Glasses and a Lens Cap
How does the orientation of circular polarizers affect its effectiveness?
Hi,
If I am using a circular polarizer on a digital SLR, I heard that a rotating lens element will rotate the polarizer and it will basically make it useless. As I understand optics, a circular polarizer basically changes the phase between the electrical and magnetic field.
1. Am I right in saying that a cirucular polarizer is basically a linerar polarizer + a quarter wave (QW) plate.
2. So, its the rotation of the linear polarizer element which causes the problem, since it can either polarize or not-polarize (according to the orientation).
Any suggestions, links, etc.?
Thanks.
You are correct in both of your assumptions. The QWP needs to have the polarization axis of the incoming light be fixed at 45 degrees to its optic axis for it to produce circularly polarized light. As long as both elements of the circular polarizer rotate together it will produce CP light. Unless the CP is two separate elements, one on the front of the lens and one at the back, somehow mounted to the camera body so it can't rotate with the lens, what you were told isn't true.
