Originally posted by Jimbo Appreciate ytou kind words. I was asked about the 14mm I use on a number of my wide angle shots using my Pentax 12-14. When I add a ND filter and go all the way out to 12mm I get some of the filter holder showing up on the outside of the4 frame. I even have one designed for wide angle lenses but still get it just slightly so I now set to 14mm. JIM
I also love the second shot. Really out of this world-like, with the strong but still believably natural colours.
For the wide-angle vignetting: I use a standard Cokin P holder, from which I simply cut off two of the three slits. The remaining one slit is enough for me (never combine filters) and it doesn't vignette even at 10mm with my Sigma 10-20. The "surgery" took about ten minutes (including finishing of the cut with sandpaper).
