Can anyone recomend a good quality polarising filter for use with the D70s. Am i correct in thinking that it needs to be a circular type filter?
Once i have fitted a screw on polarising filter, will it rotate without unscrewing? - odd question i realise but stuck offshore and looking to spend some money.

Thanks Scoobynet Collective

Hoya make good quality filters, however, if you have (like me) more than 2 lenses with different diameters have a look at the Cokin or Lee filter systems that use a carrier and a sheet system. My thinking behind this is if I buy screw in filters for all my lenses I'm going to end up with a set for the 67mm and another set for the 77mm ones and at 15 - 30 quid each not cheap.

Certainly with the Cokin set I'll end up with 1 set of filter panes abut on 2 different holders, its more expensive initially, but cheaper in the long.

Forgot to say.

With the circ polarizing filters they screw into the end threads on the lens then a seperate carrier rotates within the housing rotating the filter element.

Simon's point is valid. Many people go for the Lee or (the cheaper) Cokin systems especially if you have different filter sizes for your lenses. In my case I bought into the Cokin Z-Pro series simply because they were cheaper than the Lee system and I really only needed this type of system for use with graduated neutral density filters.

Most of my lenses have a filter size of 77mm so I bought a couple of B+W screw-in polarisers several years ago. The quality is top of the range. One thing to note -- if you are using a wide angle lens (say 24mm or shorter) then you should purchase a slim filter as otherwise you run the risk of vingetting. In my case I have two circular polarisers (both B+W) -- one is a think and one is a thin -- the only reason being that I'd bought the thinker one for use with my 80-200 zoom before I'd bought my 17-35 zoom where it vignettes so needed to buy the slimline one.

Totally agree with all the above replies. I bought a 77mm Canon screw in polarizeing filter as all my lenses are 77mm. I also have the Lee drop in filters which are a beaut to use. My system holds upto 4 slide in filters so you can use a selection of different filters for different effects.
