Which filter should i get? ASAP please going to purchase now.

It's very sunny in Australia should i get a Polariser or Neutral Density?

And for how many stops 1, 2, 3?

I need a reply ASAP

All of the above!!!

They both serve different purposes. lostdoggy is correct.

I use a C-Polariser some times if it is really bright, and im getting a lot of reflections. Not sure about a ND though. Are you asking what brands are good?

Sorry for jumping in here but I am looking for the same sort of thing. Although I am in Ireland not just as sunny. What are the purposes of the filters and on what occassions do I use them. I heard HOYA were a good manufacturor? I was told to go for a Circular Polarizer but there are different types and prices.

Any tips help useful

A polarizer will help reduce reflections from non-metallic objects (glossy paint surfaces, glass, etc.) and will make blue skies (at an angle from the sun) more intense. Neutral density filters will reduce light across the board, if you need to use a wider aperture for DoF, or a slower shutter speed to blur motion (as in running water).

Cheers jon. Think I will buy both and see how I get on. I have a skylight 1A filter cant see any difference but then again I dont know what this type of filter does to look out for.

You do know there are Graduated Neutral Density Filter use when one half of the image/view is brighter then the other half.

Skylight 1A, like UV, will take out some of the UV and purple end of the spectrum, helping cut through haze (but not as well as a polarizer will). They're also used to protect the front element of a lens, but make sure you have a good multi-coated one. Mine are B+W or Hoya multicoated.
