The Schneider 77mm True-Match Vari-ND Filter is a solid variable neutral density filter providing a reduction of about 1.3 to 11 stops. The 0.4 to 3.3 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, allowing you to previsualize the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
This filter perfectly matches two opposing polarizing foils in order to accomplish the variable ND effect, and this precise combination allows a higher level of blue color shifting at maximum density. Because both filter substrates are combined into one filter ring, this filter is low profile and helps to eliminate vignetting on most lenses. The front filter ring diameter is 96mm in diameter, further helping to reduce vignetting, even on wide angles lenses. Schneider filters are diamond-cut from crystal-clear water-white Schott glass and polished to precise flatness and parallelism standards.

Comments about Schneider 77mm True-Match Vari-ND Filter:
I wanted this filter to slow down the shutter speed in bright light. Originally I was considering some other brands at the same price point, but the design and performance of this filter really stand out. First, it has a greater ND range than every other filter I could find. Second, though threaded in 77mm in my case, the filter surface itself is larger, like having a built in step ring. This prevents vignetting. Third, the filter is quite thin, about the same as a thin mount polarizer. This is amazing considering most other filters I found are as thick as three standard filters. Throw in the Schott glass and the brass construction and this filter is almost perfect. There is a slight amber color drift at maximum effect, but due to physics is unavoidable. 5 Stars.
