I am looking for an affordable (Lee is just too much) Neutral Density filter system (also including graduated filters). I have tried Tianya (and found them terrible - as it causes red/pink overcast) and not suitable.
I want to be sure that those who use Cokin have found them reliable and effective. Also whether there is anyone here who would be able to give his/her opinion on those variable ND filters that are screwed onto lenses. Are those (about $80 for 77mm) worth the money and does it do the job? I still need a hard edge graduated filter recommendation in any case.
Hope to hear any useful inputs! Thanks!
