What you think? Too much?
Fitting it to a 24-70mm Sigma F2.8

The problem with buying (say) an 82mm one is that you'll eventually need to buy one for every lens you own.
If you are using a polariser, at some point you'll probably want to use ND Grad filters or just plain ND filters. Whatever system you choose for those filters will also have a polariser as part of the range. That gives you a single polariser for all you lenses.

Beats overrated Hoya in every way and it's much cheaper. Marumi rules![]()
Seriously? Or sarcasm? Don't want to order soemthing to regret lol
Not sarcasm at all. Marumi's ae great; very good quality, easy to clean (much easier than Hoyas). I can only recommend it. Try it, I am sure you will be able to return it if you won't be happy; but personally I have a few of them in different sizes and I will never go back to Hoyas.
Can you please ellaborate a bit more on why you like these over the Hoya, which are not as expensive as the B+W?
A good point actually, my Hoya UV filter is a pain to clean. Marks very easily, and even with Eclipse cleaning solution and pec pads it's a pain to stop it from streaking.

Very true, I have three 77mm ones that I don`t use anymore.I also noticed an improvement in my pictures when I removed them from the lenses.
Are you saying that you get better shots without the CPs?
OK, I get the picture (excuse the pun) ... but how do you rate the Marumi? And, would it be suitable for the Sigma 10-20mm? Or would that lens be too wide for the bezel of this CP?

You say that you would recommend the B+W, does that suffer from smear like the Hoya? Afterall, there isn't that much of a price difference between it and the Hoya Pro1 SHMC!
No, perhaps I caused confusion.I now have a Marumi CPL, I had Hoya Pro UV`s on all me lenses as well as using a Hoya Pro CPL, I took then off for a trial,after reading something by RobertP I believe, my pictures were better,they are a right arse to clean, I nearly always have lens hoods on and am careful with my stuff, so I don`t use the UV`s anymore.
