Polarizing filters! - Steinar1 - 12-24-2010 Please help me all of you who know; Can I use the same polarizing filter for my Sigma 10-20 and 24-70? (both 82mm <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/sad.gif' class='bbc_emoticon' alt='' /> ) Second question; Please recommend a brand/type for me. I want first class quality, but not to pay for a brand name, if it is not necessary. Thanks in advance and merry Xmas! Kindly Vieux Loup Polarizing filters! - wim - 12-24-2010 Hi Wolf, In principle, yes. You'll just have to check whether the 10-20 doesn't vignette at 10 mm and infinity focus with a standard thickness pola filter if it isn't a slim version. It will likely work, however. Just try shooting a well illuminated wall, from any distance, with the lens set to 10 mm and focus on infinity, and the filter mounted of course <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />. If you only have a gradual light fall-off towards the corners, you should be fine.

Kindly Vieux Loup [/quote] Hi Wolf, I was using a slim circular B+W on the Tokina 11-16mm. The quality of the glass was superb and the screw thread was as easy as it can be. But as you know, using a polarizer on UW lens does not help with the dark blue skies as expected. A slim 82mm B+W polarizer can be quite expensive, but still, if the dark blue skies are not the only aim for you, pay more and buy a slim one and use it on both lenses. That way, you won't have concerns for the 24-70mm, if you switch to FF in future. Regards, and Merry Christmas Serkan Polarizing filters! - Brightcolours - 12-25-2010 Get a good multicoated one, like for instance a B&W. Your probably do not need a slim one, a normal profile B&W should do fine too on the Sigma 10-20mm. But of course, that is quickly found out in shop. Contrary what is being said above, you can of course well get a very dark sky with an UWA lens. Only thing is that the sky will not be as even of shade as with a lesser viewing angle, that is the nature of polarized light distribution. So anyway, yes, if both have the same thread size, both can use the same pol. filter.

It seems a slim good quality will do the job. I know I can get the Hoya in time for Jan 1 departure, but the Marumi I don't know. I'll let you all know how it worked out. Caribbean sun will justify the use and hopefully the results will be OK!

Now I have even more to spend my time on They seem to be very scientific about their tests -- too bad they're less thorough about the practical values of their results. Their UV filter tests, for instance, don't even mention that digital cameras (in most cases) have a built-in UV filter that makes their results much less interesting. -Lars
