Hello.

Ok if I have a Sigma 10-20mm. Would I beable to combain a CPL filter with a 10 stop ND, or would this cause severe vignetting as effectively it would let in about 12 stops less light, right?

Would I be better getting a CPL and say a 6 stop ND?

Do people here combine the two or do you just use one or the other?
 
stacking filters increases vignetting yes,

but i wouldnt even attempt your suggestion i would get 10ND and a cpl totally different uses not meant for combinations as you turn the cpl for your results with a 10nd or even a 6nd i doubt youd see clearly enough to get uses from the cpl itll basically be cancelled by using the ND.

some lens cause vignetting from factory wide open so adding a filter will ony increse this hence hoya pro 1 (as e xample) being so slim to help stop this.

Very good point, I hadn't thought I wouldn't actually be able to see the effect of the CPL through the ND :p

I also didn't know that about Hoya Pro 1 filters being thinner.

Thanks dude. I am getting a Sigma 10-20mm and a 10 stop ND, I think I'll probably get a decent CPL for it to reduce vignetting wide open as you say.
 
SUPER HMC PRO-1 Multicoated Filters
These outstanding filters offer revolutionary performance in light transmission and colour balance. 12 layers of Super Multicoating are applied to the surface of the Skylight 1B and UV models, which produce an average transmission of 99.7%. Coupled with maximum surface precision, this allows increased resistance to flare the stunning images can be recorded at wide apertures without compromising the performance of your lenses. Our ultra thin Circular Polariser filters have seven layers of Multicoating applied to their rear surface to eliminate internal reflections and ghosting. Advanced thin selective film is used to guarantee perfectly polarised light with neutral colour balance. Their slim profile of just 5mm avoids any vignetting problems and makes them ideal for use with wide angle lenses. HOYA Super HMC PRO-1 filters will appeal to the most demanding of photographers who require the ultimate in performance.



Hoya Super HMC PRO-1 filters are available in the following sizes: 49mm / 52mm / 58mm / 62mm / 67mm / 72mm / 77mm / 82mm

HMC PRO-1 filters are available in the following filters only: Skylight 1B / PL-CIrc / UV




your lucky that lens is a usual 77mm fit it if were the usual sigma big end 86mm add a few £, youll get a shock at super thin pro1 prices anyhow i think,,

good luck anyhow
