Default Circular or 'A' series filters

i am going to get some filters soon and was looking into the nromal round screw in filters for my canon A70, when i thought of using square 'A' series filters and a filter holder which could prove more useful and cheaper, eg the grad filters, i could adjust easily with a square filter compared to a round fixed one. what do people think??

I am not very sure regarding adjust easily. Unless you are using special effect and gradual ND filters which need adjustment, other filters have uniformly colored surfaces that do not need adjustment. As for polarizers, Cokin's A- and P- series polarizers are of circular shape just like all other brand products.

My P-series Cokin gradual filters are square actually: the Neutral, and both the Pola Blue-Yellow (P173), and Pola Red-Blue (P171) are all squared (the P-holder rotate)!

Cokin only calls 160 and 164 polarizers. The 161, 162 and 163 are referred to polacolor, while the 170, 171, 172 and 173 are varicolor. Although 161-163 and 170-173 are listed in the polarizer category because they use the concept of polarizing light, they are not in the traditional sense of polarizers that eliminate glare and reflection. So, as far as I know (and I have), only 161 and 164 are circular.

i was going to get a kood filter holder as they do one and 52mm adapter ring, so it can fit on to any 52mm lens, those cokin ones for non slrs look a bit annoying to put on abd look a bit clupmy.

For regular photo outings the Cokin stuff is too fiddly and fragile...get yourself a standard screw on polarizer, and you can always screw on the Cokin onto that as your polarizer will have threads as well, just for whenever you want to do your creative stuff.

BTW, I have the A system for my Oly C-700.
