Kenko RealPro ND8 Filter

Neutral Density filters are the most commonly used along with C-PL and UV filters. These filters, instead of the ones that protect the lens from damage or UV pollution, were created to decrease the volume of the light entering the lens. True ND filters decrease light equally to achieve the same density through the all visual spectrum giving no changes in color balance of the image. That is why the called Neutral Density.

Why ND filter is important

We have already entered the era of super high sensitivity, super high resolution photographic equipment. Obviously, the power of this huge sensor can easily be affected by lenses and other optical accessories that are located right on the path of the light entering the camera. In other words, the filter quality serves as the front “gate” for the light to enter and is of the utmost importance.
In particular, ND filters have become a must for high sensitivity cameras with ISO settings that starts from 200 or 100. This is the reason that ND filters currently garner a high level of attention and have strict quality requirements. Professional photographers requires ND filters that decrease light volume in the most natural and harmless way.

When to use ND 4/8/16 filters

Kenko REALPRO ND 4/8/16 present the highest quality of Neutral Density filters designed to use with latest DSLR high-sensitive cameras that will allow photographer to realize photos with shallow field of view achieved by aperture wide open during the shiny day or in over lighted conditions. Kenko REALPRO ND 4/8/16 filters is recommended to use in portrait, video and nature genres during shiny day where widely opened diaphragm to prevent overexposure and achieve shallow depth of field is required to separate foreground object from background.

To choose ND filter with suitable density, use the spread-sheet below:

ND Vacuum Deposition Technology

To achieve the best neutrality in the world Kenko REALPRO ND 4/8/16 filters adopts ND Vacuum Deposition Technology. According to this technology, neutral density is realized by ND substance that coated in the steam oven equally spreading over the filter glass surface.

As a result, compared with other brand ND filters, Kenko REALPRO ND 4/8/16 perform excellent neutrality through all visual light spectrum ensuring stable color balance of the image

IR pollution

These two shots show the example of IR contamination when black objects like black suit and socks obtain brown reddish tint while leaves and trees became yellowish.

* ISO is deliberately set to 3400 in order to make shutter speed shorter and avoid motion blur of the person.

Anti-Reflection multi coating

Usually sensors of digital cameras are more sensitive than film. That’s why highlights can affect the image, creating unwanted effects due to light refraction in the lens. Filters, as they are also optical elements, can make the situation even worth. That is why filters need anti-reflective coating. Kenko REALPRO ND 4/6/16 filters adopts anti-reflective multi coating to eliminate even small chance of unwanted flares and ghosts in the image.

Basic features

Kenko REALPRO ND 4/8/16 filters has also the following additional features that will help photographer to achieve the best results

Slim Frame

Frame Use with any lens and with no loss of light. Kenko REALPRO ND 4/8/16 adopts ultra thin frame to avoid vignetting effect on wide and super wide angle lenses.

Knurling Edge Frame

Black Almite Frame

To reduce to minimum any unwanted reflections Kenko REALPRO ND 4/8/16 adopts black aluminum satin finish almite frame. Satin finish will increase friction between fingers and frame for quick operation and satin black frame will minimize internal reflections.

Black Rimmed Glass

UV Protected Case

Kenko REALPRO ND 4/8/16 filter comes with durable plastic case with UV-Cut function.
