Tokina Cinema Pro Square 4x4 inch IRND 0.3 1-Stop Neutral Density Filter
Tokina Cinema Pro Square 4x4 inch IRND 0.3 1-Stop Neutral Density Filter


 

Authorized Dealer Most of today’s high-end cinema cameras do not come equipped with a built-in low-pass or IR cut filter since they try to mimic the human eye and receive as much data as possible from the image subject. The PRO IRND has a 2-stops light reduction equal to a ND optical density of 0.9.

The more sensitive cameras are to light, however, the more exposure needs to be maintained using a stronger ND filter which in turn creates infrared pollution. To alleviate this issue, many camera manufacturers recommend the use of an IRND filter, even though many of the IRND filters on the market today have adverse side effects that come along with them such as color shifting.

In addition to this, after adding or replacing an IRND filter, the white balance needs to be adjusted to maintain true color fidelity, which can quickly become too much work. In the end, the benefit of cutting infrared pollution doesn’t seem like much of a benefit considering the need to continually white balance during a shoot and then correct color shifts in post.

Crafted to Precision for the Art of Cinematography

In terms of the development team at Kenko Tokina with their innovative Accu-ND Technology, creating a Neutral Density filter that precisely controls the amount of light entering the lens without affecting the color. A revolutionary filter that stabilizes the transmittance of color throughout the visible spectrum. The Tokina PRO IRND filter is available in 2 styles, round and square/rectangular.

In terms of the development team at Kenko Tokina with their innovative Accu-ND Technology, creating a Neutral Density filter that precisely controls the amount of light entering the lens without affecting the color. A revolutionary filter that stabilizes the transmittance of color throughout the visible spectrum.

The Tokina PRO IRND filter is available in 2 styles, round and square/rectangular.The round PRO IRND filter has an ND vapor deposition coating on both sides of the glass creating a high precision, truly neutral filter. The square/rectangular type of filter has an ND vapor deposition coating sandwiched between two layers of glass so the filter can be re-polished again and again should it get scratched, extending the life of the filter.

There are generally two types of IRND filter manufacturing processes currently in the market today. One type cuts the near infrared from a particular wavelength and the other controls rather than cuts the infrared up to1200nm. The Tokina PRO IRND filter is of the latter category, using suppression rather than cutting to eliminate infrared pollution. Even though both methods can be equally effective, the former type of cutting is often prone to producing unwanted color shifts.

Tokina Cinema Hydrophilic filters for broadcast and cinema use. Tokina Cinema Hydrophilic filters have a coating layer that does not allow water to bead up like traditional filter coatings. If water cannot bead it simply flows evenly off the filter surface making for clear viewing and recording even in a steady rain.

Water-drops on glass are formed by surface tension and adhesion. Once the weight of the water is sufficient to overcome the strength of these two forces the water beings to flow. This can be seen every time water drops first “stick to” and then cascade down a window when it rains.

The Tokina Cinema Hydrophilic coating does not allow surface adhesion so water drops cannot form. The coating Tokina Cinema Hydrophilic filters permanent and does not ever need to be reapplied, unlike over-the counter products that make a similar claim. The filter coating is “recharged” by UV light making it ideal for stationary weather cameras or other cameras that are being exposed to sunlight for several hours a day.*

Tokina Cinema Hydrophilic filters come in standard broadcast sizes from 77MM to 127MM as well as square and rectangular.

When water from rain or spray hits normal filter glass it beads up in droplets that degrade image quality. The Tokina Cinema Hydrophilic filters have an exclusive specialized coating to ensure that when water hits the filter, it spreads into a film over the glass instead of forming droplets. This helps to maintain a clearer view under a variety of weather conditions.

Through a special treatment of the hydrophilic surface, this filter is also extraordinarily durable.
Some more interesting and exciting developments out of IBC 2013 -- Tokina showcased their water dispersion filter that will keep you from cringing when you see those dark clouds coming to rain on your parade (or set.) Tokina has done something with their filter that has not yet been done -- used a special hydrophilic coating instead of, say, a vibrating mechanism to keep water from accumulating, keeping lenses dry. Read on to get the details from a video by News Shooter.

Tokina partnered with NHK, a Japanese company that has been on the cutting edge of many developments in broadcasting, like their multi-viewpoint bullet time camera setup to produce the waterproof coating that works like similar coating on car windows and other glass, so as to not allow water to bead or gather forming droplets.

Though its intended use is by broadcasting professionals, this kind of lens would be so incredibly useful for not only that, but documentary filmmakers -- even narrative filmmakers shooting on location in a rainy area, like, I don't know, the Pacific Northwest -- a place where spotting tourists is as easy as spotting their umbrella.
