SKU: KF01.1080

Q
Which variable nd filter is best the nd2-nd32, nd8-nd128, nd2-nd400 or nd8-nd2000? i am shooting outdoor music videos in bright sunlight?
Answer Question
A
This really depends on multiple variables, but I would suggest the 8-128. The 2-32 will do well, but if you're shooting at 24fps, with a 1/48 (or 1/50) shutter, then it gets bright, so the extra couple of stops to 128 can be helpful. ND8-128 will give you the ability to just crank your ISO up a bit if the ND8 is a little too much as the sun gets dimmer.
A
The 2-32 wont be enough in the brightest sunlight to open up fast lenses, and the 2-400 spans far too much range to actually work well outside the middle of its range.
