About using the Canon Drop-in Circular Polarizing Filter PL-C 52?

Hi Forum Readers!

About the use of the Canon Drop-in Circular Polarizing Filter PL-C 52
I am a bit interested in how often you actually use this filter and in which situations you find the desirable use of the Drop-in Circular Polarizing Filter PL-C 52 with your tele-lenses from Canon?

The benefits may be the many?(I am considering if this filter would be part of my equipement?) but there is also this fact of a light loss of up to 2 stops, but maybe a fast glass like EF300mm with f/2.8 would be the right lens to be equipped with this filter? Is the filter-effect affected if you are using the lens stopped down (like f/8)?

I am mostly interested in the end result,what the Drop-in Circular Polarizing Filter PL-C 52 can add to your photographs compared to photos without this filter.

Anyone here who maybe like to share something, about your experiences, when you are using this filter?

Wishing you all a very good new year 2014!

Greetings to you all!

You'd use it whenever you'd use a CPL on a lens - to darken skies, reduce reflections, increase color saturation, etc.  It costs ~1.75-stops regardless of aperture selected, and the polarization works at any aperture.  I use one when shooting shore/water birds, for example, provided there is adequate light.

I use CPL whenever light conditions approve it. For Macro shot always. I like that saturated colors.
