The Nikon CIR-PL II cuts only 1/3 stop of lightspurssy said:3. Reduce exposure
Most pple use it for 1 and 2, though you have to take note that they work against each other (if i remember correctly).

In layman terms, a polarizer can achieve 3 main things:
1. Enhance colour saturation (esp. skies)
2. Cut amount of reflections
3. Reduce exposure

Meaning, you can place a 62mm filter over a 52mm lens front by way of this adapter that step up the filter size.
Yes it does....I wrote that sometime ago in another thread. I was thinking of putting it in here but....thought adding too much details will lead to more confusion heh.spurssy said:How much on average does this special filter costs? I read somewhere that such step-up method actually reduces vignetting also. What do u think?

espn said:Yep, that's why originally when Nikon launched their 77mm CIR-PL, it was a 77-82mm thread. To reduce the vignetting on WAs.
The screw on thread is 77mm to fit the len, and then it steps up to the rotating ring size of 82mm, so there's prevention of vignetting at the wide cos the filter is 82mm wide infront.spurssy said:What do u mean 77-82? double diameter?
