For my planned Nikon setup, I am debating between the Nikon and Tiffen Circular Polarizers. I have had the Tiffen with my previous setup and was very happy with it, but have heard great things about both. Obviously, the Nikon is considerably more expensive. What opinions do others have? I am looking at a 62mm that will fit all 3 lenses I'm looking at for my collection; Nikon's 24 - 50 D, 60 D Micro, and 70-300 D ED. Also, do both cause a reduction in the f/stop? As I seem to recall, I believe the Tiffen stated it causes a 2 stop loss of light, but I'm not certain of that. Thanks, Ross ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
