I see that Hoya do a combined Circular Polarising and UV filter? Do you think this is a good idea? I don't really know enough about filters yet to know whether it's better to have 2 separate or one combined. It would certainly cut down on changing but would you want to have the CP on all the time or just for certain conditions?
Thanks in advance for youradvice & help.
A polariser will add 1 to 2 stops so cutting down the light entering the lens. To me its not a filter to keep on all the time. Some people keep a uv on all the time I prefer to put them on as i need them
