filters for lens that don't have filter thread
have to use cokin x pro gnd...
the next question is 10 stop nd... i search until end of earth still cannot find one person having done so... only a few managed to attached a filer (CPL or uv)....
a 10 stop nd is more problematic... u need to be sure that there is no light leaking... the requirements are higher than a CPL or UV...
pls contribute if you have anything to share....

Re: filters for lens that don't have filter thread
i think it is possible to use gnd and nd on all these 3 uwa (sigma 12-24, nikon 14-24 and olympus 7-14mm).
the answer is the expensive Lee filters.. u just need the adaptor rings (95 mm for sigma etc) and get the hitech gnd or lee gnd and the Lee Big Stopper!!!!!!
