I’ve recently been testing a innovative new filter system by Kenko which I have to say is one of those things that is so obvious that it makes you think why wasn’t this done earlier! -> Read more details

As a result, compared with other brand ND filters, Kenko PRO ND100000 filter performs excellent neutrality through all visual light spectrum, ensuring stable color balance of the image and natural color rendering, without unwanted color shift.

A linear polarizer only differs from a circular polarizer in that it does not contain a quarter wave plane that enables use of auto focus and exposure features. Linear polarizers are best suited for use with manual cameras, such as view cameras, that are not dependent on internal mechanisms to determine focus or metering settings.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 10,000th of an inch, and then mounting to precision metal rings.

The Tiffen Linear Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

The University of Arizona Wyant College of Optical Sciences is one of the premier educational and research institutions in optics and photonics worldwide.

This filter can be also used in combination with Kenko Stepping Ring (step-down or step-up, separately sold) to adapt to smaller or wider diameter lenses.

Developed with the highest Kenko quality, PRO ND100000 filter is especially dedicated to solar and solar eclipse photography. This filter can in fact reduce the amount of light hitting the lens down to 1/100000th (16 3/5 f-stops).

A solar eclipse is a rare phenomenon every photographer do not want to miss. Dedicated ND100000 filter is usually recommended when photographing a solar eclipse.

To achieve the best neutrality in the world, Kenko PRO ND100000 filter adopts ND Vacuum Deposition Technology. Through vacuum deposition, ND substances are equally spread in a steam oven to evenly coat the glass surface of the filter.
