I've just acquired the Pentax-DA 15mm f4 Ltd.
One of my main areas of interest is shooting sunrise/sunsets so I investigated my options for a ND Grad filter. Wow, what a can of worms I seem to have opened, the main issue being vignetting.
My Cokin 'A' series holder won't cut the mustard and the 'P' series wont either.
So it's either the Cokin Z-PRO or the basic Lee set up. Where does it stop?
Maybe I'll just hold a filter in front like another member suggested.
Any suggestions appreciated as I'm now broke after the recent bout of LBA.
