I got this question today from Sandra:
I am getting ready to buy some filters and had a few quick questions. On the Singh-Ray filters, I see there are warming and neutral polarizing filters. Which one do you recommend?
Should I use a polarizing filter on both the 10-22mm and 15-85mm lenses? I read something that indicated not to use it on the 10-22 mm lens.
If I can use it for both, can I buy one filter and use rings to fit the other lens?
I have been researching online which means I have seen about 100 different opinions!
Thanks for the info!
Here’s my answer:
Your 10-22mm has a 77mm filter size. Your 15-85mm has a 72mm filter size. The step-up ring will allow you to use the 77mm polarizer the lens with the 72mm opening.
Get the thin polarizer so the edges don’t show when using the 10-22mm lens.
