Canon EF-S 10-22mm vs. Tokina 11-16mm -> FIGHT!

, not able to reach on any conclusion.and what about the vignetting caused at 10-13mm with regular CPL(instead of slim)?
now, even if i get a slim CPL, i wont get better polarising effect below 15mm, so i can save money by getting a regular CPL than a slim version.

Get the regular version, unless you plan to stack the CPL onto another filter. In my previous testing, the 10-22mm @ 10mm could handle a B+W F-Pro + XS-Pro stacked (8.4mm, which is thicker than the standard CPL at 7mm), with no mechanical vignetting.
