recently while trying to find a Circular Polarizer, i found out that some of them are adjustable!

Does it means that all is adjustable ? (thru the filter with something to rotate)
And there are those none adjustable ones ? (those that is FIX)
And whether there will be price differences ?
Which one is better for a Digital Camera ?

Hope someone can answer my questions.

for canon lenses, it is stated ONLY use a circular polarizer, though if you wanted to, a linear polarizer can be used :p

all circular polarizers can be rotated, as far as 35mm lenses are concerned.

All polarisers are adjustable. Never heard of a fixed polariser. This is to allow you to vary the degree of polarisation. Do not get a linear polariser as it might screw up AF on your camera, stick to the circular ones. There will be differences in price depending on the brand you buy; a good budget option are the Hoya ones.

sehsuan was referring to the 35mm film format (which you needn't bother about for now, but can read up if you are interested to learn more about photography)

read ALL the posts above. It's already stated that with a linear polariser, the AF on your digicam would NOT work.

Linear polarizors generally only affect the Phase Detection AF systems of SLRs. Digicams that use contrast detection can use Linear Polarizors without ill effect.

A polariser that cannot be adjusted? I think you guys are actually talking about neutral or gradated density filters... all circular or linear polarisers should be adjustable to deal with different lighting conditions.

Thnx tingchiyen and guys for replying !! ;)

So the price of a 52mm one is 20+, so a 55mm one wont cost too much either.

Someone in this Forum replied to me in PM that he selling MORA 55mm for 40bucks..... Dun know whether to let u guys know his Name anot.... Somemore i guess he created multi-accounts.

Toking abt neutral or gradated density filters, what is their price like ? damnz... i paiseh to ask sia.... cant even pronounce them correctly... lolz.. :sweat:

Picked mine up from P&G at adelphi... i've received a PM from a friend telling me she got hers at $21 at the same place... guess it's about there.

No complaints about the Mora, one polariser as good as another as far as i'm concerned... the B&W ones might be way slimmer and all, but it doesn't really seem to matter picture quality-wise... just get what you're willing to pay for. My other polariser's a 72mm Nikon, and frankly, i think they work equally well.
