What polarized filter to get?

[boloto]

I have d90 and thinking about getting a polarized filter. I look at B&W offers, but they have a huge variety and range and different prices.
I am planning on using for outside sky/water/reflection photography.

Thanks!

With filters, you get what you pay for. The main features you'll want are multicoating (helps avoid glare) and real glass (which all but the cheapest have).

Otherwise, can you be more specific?

Hoya, Tiffen and B+W are generaly the best ones.

B+W lists:

5 x 5" Combination 85/Linear True-Polarizing Water White Glass Filter which is $450.00

and
40.5mm One-Stop Linear Polarizing Water White Glass Filter which is 175.00

What is the difference?

Hm, you must be looking at Cokin-style filters -- that is, square ones which fit into a slot which you attach to the front of your lens. Is that what you want? Or, you could use screw-in filters, which screw into the threads on the front of your lens. I find that those are much more portable, depending on your needs.

Also, you will need to be sure to get a Circular polarizer, not a Linear one (this has to do with the glass, NOT with the filter's physical shape). Linear polarizers cause trouble with DSLRs.

Great. Thank you.
