    Hi there,

    UV filters are used to filter or block off UV Light (invisible to the eye) which are less than 200 ~ 300nm.
    Visible Lights is within the range of 400 to 700nm, so a UV filter has no filtering effect on visible light so people usually use them to protect the front element of a lens (cheaper to replace a UV filter than to send a lens for repair and servicing).

    Stacking of filters shouldn't be an issue unless the filters are quite thick (Normal CIR-PL are quite thick as it consists of 2 layers of filters) and may cause vignetting at wide angle especially.

    For my practise, either normal or IR shooting, if I need to use a CIR-PL or R72 when shooting, I will remove my UV filter if I am shooting at wide angle range of less than 24mm just to prevent vignetting due to filter stacking.

    Just my 2 cents worth of thought.

    But it can still be done, so your claims on 35mm format can't work is thus false.

    i remember stacking a normal Hoya Cir-Pol on top of a cheapo Tokina UV filter on a 28mm lens using an SLR (film).

    no vignetting.

    What a load of C R A P. Do you even know what you're saying? Oh wait! Bro ESPN is right. You're the filter pro, better not argue...

    Then again, never knew talkingcock had a share in this forum.

    Back on topic, I don't see any problems. Even with a 12-24, I haven't noticed any vignetting with a normal CPL. Unless I didn't look closely enough. But other than the possibility of vignetting, I don't see any other problems...

    i tried using my hoya HMC with a kenko CPL stack on it on a 18-70mm. visible vignetting images.

    but then again, i do see vignetting on the 18mm end with jus the HMC also.

    Stacking for the wider angles may cause some problems. As such, it is always a better idea to remove the UV filter before using a CPL for the wider lenses.

    UV filter will not reduce the light passing through. Only the polariser will reduce 2 stop. So i have no problem with two filter on at the same time.

    There is reducing light on UV filter. But the amount of light loss is negligible. Multi Coated one is better than Single Coated. Single Coated is better than non Coated one.

    UV filter will not reduce the light passing through. Only the polariser will reduce 2 stop.
    Is that means I have to increase 2 stops of brightness to balance out the difference?

    No need. Camera will metering everything that goes trough the lens (and CPL and/or UV filter).

    Unless you use handheld light meter, you must increase 1.5-2.0 stops (depends on CPL brand).
