Filters

Ret: That filter should do you just fine.

MikeS: Yes and no; CPOLs do reduce the light hitting your sensor (by one stop), but they aren't tinted. They're optically neutral, meaning that they block light but impart no colour caste or tone on the image.

I should add that the better quality and more expensive polarizers bock even less light.

I hope that I m able to take a shot that comes close to the one you posted. I think that shot is just beautiful and with your permission can I use that as my laptop's wallpaper

btw, the CPOL that i got is Hoya Super HMC and on Hoya's website they have PRO -1D filters so whats the difference b/w them or are they the same?

Oh? All of my experience shows that good ones block almost exactly one stop; my Hoya blocks almost exactly one stop, my B+W blocks almost exactly one stop... some, like the Singh-Ray Blue/Gold warming polarizer actually block slightly more, but AFAIK, it's only the really cheap ones which will block significantly more.

You're more than welcome to use that as your wallpaper. With respect to your question about the filters: The answer is packaging. The "D" and "DMC" designations that Hoya applies to some of their filters is meant to imply that these are filters specifically for digital cameras. A CPOL is a CPOL is a CPOL (Quality issues aside of course) and these filters will produce identical results under identical conditions.

As with lenses, price is an excellent quide to quality, at least among name-brand products. If the price is the same, you can be the characteristics are the same (Or darn close).

thanks for the wallpaper, i mean pic

i talked to Henrys and the rep suggest the pro-1D .... it's a little darker than the S-HMC but has the thread in the front to put on lens cap .... and it's price went down from $199 and now is the same as S-HMC's .... i swapped the S-HMC with Pro-1D

Disadvantage with a UV filter is that in combination with a polarizer, it can often cause vignetting with a wide angle lens. As a result, a number of photographers are keeping a polarizer on for almost all shots rather than playing with taking a polarizer or UV filter on and off.

Tegan

True that and it IS a problem. I hate fiddling with both the UV and polarizer...but I do all the time. Although I use a polarizer often, when I'm not using it, I don't want it on the camera (light loss -colour cast albeit small)...hence the fiddling.

Is it advisable to shoot with the CPOL always on the lens and shoot with it most of the time?

No, it's not advisable. It won't hurt other than to cost you one exposure stop, which can make the difference between getting the shot and not getting it. I would put it on when you need it and remove it when you don't.

I have found it useful to have on the lens most of the time. Outside it improves landscape shots and handles glare and reflections. Inside it reduces the harse glare of flash. I even used it in a dark situation in a mine to reduce flare from a light toward the other end of the shaft.

i think most cpol's cost you 2 stops
