Default Filter +Filter.

Hi,
I have the Nikon 18-200mm with a Hoya Pro 1 uv filter on and I'm thinking of getting a Hoya HD Circular Polariser, as they are both Slimline do you think I would get away with have one on top of the other, or would the CP light loss be minimul so allowing me to keep just the CP on all the time.
Both being thin I'm thinking vignetting might not be an issue either ???
Thanks

The light loss from the CPL will not be minimal.

Also, even with the best filters, each air-to-glass interface degrades image quality. I wouldn't make the situation worse by leaving the UV filter on too. And that doesn't even count the additional vignetting from having two filters mounted, thin or otherwise.

Thanks for the links TCav,
I guess I'll probably swap them around now as needed if I do get the Hoya .
I'm having to convince myself it's nescessary due to the price.

If you want to use a filter, don't scrimp. The best indication of quality is price.

TCav - good post
Another good site is
http://www.tiffen.com/camera_filters.htm
About the only time I stack filters is with the ND's [ I have 2 ND 3's and an ND 6 ] If I want a weird ND / non stand / want ever you want to call it I have stacked a CPL and ND together .
From the way I read it , you don't know if you want to spend that much on a good CPL .
2 lines of though - a bad picture is better than none - or don't bother , you will not like what you get .
Anyway get a rubber hood .
vignetting is something you deal with - i Just figure I will crop if it shows up .
