Anyone has experience stacking ND filters? I'm talking about stacking circular filters that attached directly on the lens, not the square filters that put on a filter box (I'm not sure if there is any difference for these two methods though). I read people saying some issues when stacking ND filters (flare, glare, color shift etc). And some people said if using high quality ND filters with IR blocking can get good results. I'm not consider variable ND filters because they are not enough stops (3-8 stops). I need 10-15 stops. I was thinking to stack maybe 2 to 3 with 10/3/3 stops filters, so I can have a choice of 10/13/16 stops. Some recommend B+W ND MRC filters, already quite expensive (for 77mm 10 stops ND costs US$149 in bhphoto), but still I don't see it features IR cut.
Please advice and share your comments. Thank you masters!
for circular filters iinm you can get up to 10 stops (Hoya nd400 = 8 2/3 stops / B+@ nd110 = 10 stops / cheap nd1000 filter < rm100 oso have but more pp needed for color cast correction & IQ degradation may also be issue).
stacking may be an option but you may get vignetting , might not be an option for those who shoots ultra wide angles.
another is the IR filter, there are few variants but i donno much about them. sorry
best option is stacking filters on filter holders.
lots of sizes for different purpose and lenses. (cokin A/P series , Z series or 100mm filter, 150mm for Nikon 1424 UWA)
for these stacking is best, more options too (nd , gradual nd, reverse gradual nd, blah2)
my suggestion is go for the last one,
get the 100mm filter series, there are generic brands for filter holders and filters that may cost less than u think
easier to get filter holder and buy step up rings than to buy circular filters for every filter size.
cheers
