HOYA PROND16 GRAD filter represents blender type graduated round filter designed to balance the luminosity of bright areas with the dark areas in the image. Suggested for those photographers who are specializing mainly in landscape photography. A blender type filter is highly versatile and can be used in a variety of situations, especially when the scenery and horizon have a complex or uneven structure. HOYA PROND16 GRAD filter incorporates ACCU-ND technology, providing the highest quality and the best experience for the photographer.

For JPEG users it is a crucial output. Graduated filter helps to adjust the luminosity of a bright sky with the terrain and as a result we have excellent, overall well exposed ready-to-go image.

For professional photographers who work with RAW data, graduated filter will help to preserve rich pixel data in bright areas. That will make further post-editing process easy and time-saving. Especially this issue concerns bright areas, where pixel rescue is the most difficult process.

Blenders can be used for a variety of scenes especially when the scenery and horizon are too complex to hide the transition of a soft edge filter. Blender type HOYA PROND GRAD filters are extremely versatile and easy to use.

Rotation frame allows precise gradation adjustment according to the composition or subjects positioned inside the image.

HOYA PROND GRAD adopts ND deposition process technology that allows gradation to be distributed equally through the entire filter glass surface. However, to maintain true density value inside the image area we adjusted the effective blending area in the way that the specified density would start and fade out inside that image area. That will help photographers to apply the required density to the image in the most effective way.

HOYA PROND FILTER is a high technological product targeted for both still photography and HDSLR video markets. The PROND filters use HOYA’s exclusive clear optical glass that incorporates a metallic coating on front and back side to equally reduce almost all range of the light spectrum even in the IR area. The ACCU-ND technology used in the coating process perform a truly neutral color balance that will not add any noticeable color cast to your images.

THE POWER OF A TITAN
The HOYA HD nano Mk II CIR-PL is the best polarizer you can get for your lens. Equipped with a High Transparency HD Polarizing Film, manufactured with a high-pressure press technology for maximum sturdiness, and perfected with the unmatchable ultra-hard nano coating, the HD nano Mk II CIR-PL will provide you with an unbeatable longevity and an image quality worthy for the big screen. Experience what it means to use a titan!

THE UNRIVALED STRENGTH OF THE ULTRA-HARD NANO COATING
The most vulnerable spot of filters are their coatings. A coating is not permanent. Daily usage and wiping when cleaning the filter wear the coating off. The filter protects from potential physical damage – but the coating should also have extraordinary strength in order to not wear off during routine maintenance. If the coating loses its effectiveness, the image quality suffers.

But not with the HD nano Mk II's ultra-hard nano coating. This newly developed coating is applied onto the filter's glass surface more firmly and tightly on the nano level than ever before. Due to this, the particles are layered on the glass surface with extremely high density that creates a hard to come off and smooth coating.
With 16 layers applied to both sides of the filter glass, the coating is a solid 200% harder than that of common CIR-PL filters, making it the hardest and most scratch & stain resistant coating among all manufacturers. Of course, the coating comes along with water and oil repellent properties, making everyday cleaning as easy and fast as it can get.
The ultra-hard nano coating makes the HD nano Mk II CIR-PL a perfect fit for advanced and professional photographers who are often shooting in rough conditions, allowing them to fully concentrate on the work without worrying about the filter.

HIGH TRANSPARENCY POLARIZING FILM FOR FAST SHUTTER SPEED
The HD nano Mk II CIR-PL adopts a high transparency polarizing film. It has an incredible 25% better light transmission than standard polarizing films used in current photographic filters. This translates to no less than nearly 1/2 stop more light entering the lens while yielding the same polarization effect. An absolute must for shooting in low light conditions!

CONTROL REFLECTIONS
The HOYA HD nano Mk II CIR-PL filter allows you to create unique effects in your photo which are not achievable through editing software in post production.

One such effect is the controlling of light reflections on glass or water surfaces. The HOYA HD nano Mk II CIR-PL allows you to control light waves entering your lens, through the filtering of all polarized light. This allows you to see below surfaces of water.

This effect is also great on glass surfaces. By removing reflections, you can look through the glass and into interiors.

ENHANCE CONTRAST AND COLOR SATURATION
Polarized light is not limited to surface reflections, but light shining directly from the sky is polarized too. Air molecules, moisture and dust scatter sunlight, and this light can be filtered out with the HOYA HD nano Mk II CIR-PL.

This allows you to greatly increase the contrast of the sky, removing haze, and enhancing blue hues.

A SLIM DESIGN WITH HIGH STABILITY: THE HD LOW-PROFILE FRAME
When it comes to CIR-PL filters, a common fear is: Will it cause vignetting? Since CIR-PL filters have a front and rear frame, they become naturally thicker which undeniably increases the chance for vignetting.

The HD nano Mk II CIR-PL however is designed with an ultra-thin Aluminum frame, keeping the overall thickness even for a polarizer very low. This makes most wide-angle lenses compatible to use and vignetting only happens in very rare cases.

On top of that, the HD nano Mk II brings the stability to the next level: The glass is mounted with a special high-pressure press technology to the frame. This gives the glass an extra lasting stability, increasing the filter’s overall sturdiness and prolonging its life-time greatly.

The HOYA HD nano Mk II truly sets the benchmark for the premium class of filters. Its quality excels in all areas, providing the best effectiveness and protection at the same time. This titan is recommended for advanced and professional photographers – especially to those who are frequently shooting in harsh conditions that need an extra level of quality for their filter. A truly powerful filter!

HOYA PROND FILTER is a high technological product targeted for both still photography and HDSLR video markets. The PROND filters use HOYA’s exclusive clear optical glass that incorporates a metallic coating on front and back side to equally reduce almost all range of the light spectrum even in the IR area. The ACCU-ND technology used in the coating process perform a truly neutral color balance that will not add any noticeable color cast to your images.

Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens. PL (Linear Polarising) and PL-CIR (Circular Polarising) filters have the same effect, but it is important that you choose the correct version for your camera. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer, with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. HOYA's polarising filters do not affect the overall color balance of a shot.

How to select the correct Polarising filter:
Many of today's cameras use semi-silvered mirrors or prisms to split the light entering the viewfinder in order to calculate exposure and focusing distance. PL (Linear Polarising) filters can sometimes interact with these items to give unpredictable exposure or focusing. So we recommend that you choose a PL-CIR filter unless you have a manual focus camera which has no beam splitter.

HOYA Variable Density II is a density adjustable filter with an ND range from 1.5 to 9 f-stops (ND3-400).
The difference with the previous HOYA Variable Density filter is the newly designed rotatable frame with convenient knob, allowing for better operation.

Why variable density filters are important
Variable density filters are widely used because they can replace a set of solid ND filters by providing a range density that can be adjusted according to the desired exposure settings.
In still shooting, variable density filters lower the shutter speed according to the photographer’s intentions when the shutter speed cannot be lowed due to camera limits.
Variable density filters can also increase the amount of boke when shooting in the over-lit conditions, thus, preventing the image from overexposure.
In video shooting, it is fundamental to keep the shutter speed fitting the frame rate setting. That is, to keep it equal to double the frame rate for optimal results. This is because, unlike still photography, an excessively fast shutter speed may create a jarring effect and produce afterimages that will not look good in the final video.
As you can see from the image below, unlike still image, a video clip is made of a sequence of still images. With low shutter speed, each still image will blur but will look smooth in the video sequence. On the contrary, a higher shutter speed will capture the object solid and sharp, but once in a video sequence all objects will appear separated, creating jarring and unnatural looking motion.
By using variable density filters, the shutter speed can be adjusted to the proper value to get that natural and smooth looking motion requested in video footages, as shown in the image below.

Highlighted features
HOYA Variable Density II incorporates exclusive rotatable frame construction that consists of fixed frame and rotatable frame. The rotatable frame gets wider compared to fixed frame size in order to minimize the risk of vignetting when used on wide angle lenses.

Lens cap compatibility
Due to the specific structure of the filter frame HOYA Variable Density II can take one size bigger lens cap than the size of the filter itself. For example, 77mm HOYA Variable Density II can take 82mm lens cap, as shown on the image below.

For longer exposures
Without changing the aperture, the HOYA Variable Density II provides the freedom to change the shutter speed according the effect desired. Effective for motion blurring effects like waterfalls, cars or blurred panning movement to make the subject stand out from the background.

For wider apertures
Allows wider apertures in over-lit conditions be used to decrease depth-of-field, literally focusing more attention on the subject.

Preventing overexposure
Even with a shutter speed of 1/8000 seconds, a large aperture of f/1.4 or f/1.2 can cause overexposure. With the HOYA Variable Density II filter, overexposure issues can be avoided by adjusting the light intake.

For shooting video in cinematic look
Variable Density filter is a must-have item for video bloggers and professional video content creators. Allow cine/video cameras to set the appropriate exposures in a bright lighting conditions to achieve cinematic look.
