Vignetting with stacked filters

[neuroanatomist]

Did you make any conclusions or other observations during your analysis. Looking at it, I am a little underwhelmed by the impact of the XS-Pro given the loss of front threads (am I remembering that correctly?).

I was rather surprised at the degree to which stacking filters was tolerated, in general, without an impact on vignetting.


The XS-Pro does have front threads (it's the Slim mount that lacks them). So, no real harm (except a slightly higher price) for using the XS-Pro filters. The main reason for using them, IMO, is to stack filters -on wide angle zooms like the 24-105mm and the 17-55mm you could stack a standard CPL on an XS-Pro UV but not on a standard UV, for example.
