| p.1 #6 · Question: Singh-Ray 77mm filter on 16-35L II |
Thanks very much for your comments. I just got a Hi-tech 10 stop ND filter and use Cokin P holder to use it on my 16-35LII. The blue color cast is quite obvious, and after color cast correction, the color is definitely not vibrant. If the pic is transformed into B&W, that's not a big problem. But to recover the real colors, it seems to be a little bit complicated.

For those of you use 16-35LII, how could you resolve this problem? Just stack polarizer, GND together? And I found if I stack more than one piece of filter in front of the lens, the color cast would be a problem. Though I might use grey card tricks to deal with it, the color rendering becomes really dull. Any suggestion? Thanks.Jo
You will find that even the SR VND will have problems of maintaining consistent density at very wide angles (16mm) at 6-8 ND. Also as you get to stronger ND filters (>8 ND) all filters have some sort of color cast. A 10 stop ND filters out 1/1000 of the visible light, and the IR leaking through your sensors hot filter starts to affect the residual color cast as there is so little visible light.
You will find on UWA lenses that they either have an 82mm thread, or don't take filters at all due to their bulbous front elements (like the 17 TSE, Nikon 14-24, Samyang 14, etc). The system of broadest applicability are the 4" resin filters from Hitech, Lee, Singh Ray, etc. They are available up to 10ND from Lee(Big Stopper) and Hitech/Formatt (Pro Stop). Lee and Singh Ray make excellent GND filters in the 4X6" size. Lee seems to be the most popular 4" filter holder, but they can be hard to find in stock.
