Stupid question

Sony717 · 21st May 2003

I have a sony717, i heard can use filters of other brands?
I want to get a polarised filter, is it cheaper than sony?
Where to buy one?

thanks in advance

Super newbie, still learning!

I am a ex-717 user. You can use filters from any brands, just ensure the filter thread size is 58mm. The most famous brands (some same best quality) are B+W (can buy at Cathay Photo) and Hoya (can buy at Cathay, Alan Photo, MS Color or any large camera shops)

Sorry, one stupid question from me too.. hehe
Is circular polariser necessary or a normal polariser will do ?
Cause I don't feel comfortable with my circular one. If I attach a telephoto convertor, I got this "rolling" feeling when I hold on it.

CPs are suppose to be fitted at the very end so you can turn it.

Correct me if I'm wrong.

Actually for digital cameras, whether it's a linear or circular polarizer doesn't make a difference...

linear and circular don't make difference meh ?

but i think circular gives you more control in a sense.. can choose how much light to let in and what you want reflected and not...

try it out at the esplanade with the many glass panels.. rotate the circ a bit and you get different reflections.. pretty fun.

hmm
wait
if i get a telecon, i have to get a larger thread circ pol ?!

can i just attach the telecon to the polariser.. aiyah screw it even if it spins around..

Not sure about that but it's generally not advisable to have anything between the TC and the main lens..

There is a difference between linear PL and circular PL.

It's totally two different things, the manufacturer didn't just come out with two names to have people say it's the same thing

Yes, agree ... it is different ... check your camera handbook. Some can only take Circular PL and some only Linear PL. So if you get the wrong one, the shot may not get the desired effect.

i seriously dunno what the hell it's talking about.. it's too profound man.. all these manual polariser work..

whew lucky i have an LCD screen :P

Both Circular and Linear polarizors work exactly the same way. You turn them to get the degree of polarization required.

The only difference is that Circular Polarizors have an extra layer to depolarize the light again to make it compatible with the AF sensors of some cameras.

"Digital cameras in general do not have reflection mirrors, and, as a result, can use both (linear or circular) polarizers"

I bought a Hoya linear CP from Alan 3 weeks ago at $30 (for my 717). So far, so good. A lot of people discussed this issue in dpreview.com. Conclusion, for digital cameras, buy the linear CP, cheaper!
