if you are planning to shoot at the widest end (10mm)
you probably will not use much filters. i would think you can at most use one filter at one time, even if you get extra slim ones. if you plan to use slide-in filters with the cokin psystem, then you HAVE to get the ultrawideangle filter holder version. and you cannot stack, or will get vignetting. the troubles with using uwa lens. :dunno:
I am gg to buy this lens and filter (likely CPL). I am also concerned about the vignetting. So, what should i do? Can i skip getting the slide-in filter? I got too much inventory and i keep losing my accessories.
