Hoya Solas Variable Neutral Density Filter with De-Polarization Layer and Aluminum Body (77mm)

The downside to most variable neutral density (fader) filters is unpredictable ‘color shift’, loss of sharpness, and glare. These deficiencies are caused by low-quality glass, bad multi-coating technology, cheap polarizing films, and poor manufacturing. The result is an inexpensive but image-degrading product. Results are straight from the camera. Each filter was tested multiple times to ensure focus was accurate and results were fair. Sharpness loss is a result of shooting through 4 layers of glass and 2 polarizing films. Results reflect the quality of materials and multi-coating technology used. The Hoya Solas Variable NDX filter solves these problems by using only the latest technology, premium materials, and quality Japanese manufacturing, and attacking ‘color shift’ with an exclusive ‘de-polarization’ layer baked into the optical formula. The result is a filter that maintains consistent color from 1.3-stops to 8.7-stops. Filmmakers can now tweak density as the light changes without fear of color shifting. Photographers can focus, compose, and set white balance at 1.3 stops, then adjust density as much as 8.7 stops without having to change filters.
Authentic Color Reproduction with Precise Density Control
All filters are set to 8 stops. They are adjusted for exposure only. The color is not touched in post-processing. The color is straight from the camera. And you can use your original lens cap and most manufacturers’ lens hoods. The lightweight aluminum filter frame has front filter threads so you can attach a lens cap, but more importantly, additional filters when increased density or other special effects are desired. The filter is available in 77mm because it allows for the greatest amount of precise density control. The ‘throw,’ or rotation, is greater than smaller filters. This makes it easier to achieve an exact density. The filter will also work well on lenses with smaller filter threads by using an inexpensive step-up ring (sold separately).
