Neutral density (ND) filters are the most demanded and essential type of photographic filters because of several reasons. For photographers ND filter means precise control of the amount of light passing through the lens for greater creative control over exposure. For video content creators ND filters helps much to set shutter speeds to match the frame-rate while maintaining the depth-of-field of the footage.Among the varieties of ND filters from ND2 to ND1000 even ND100000, we can generally categorize ND filters into 3 basic groups: Light density filters (ND2 – ND8) Middle density filters (ND16 – ND200) Deep density filters (ND500 – ND1000 / ND100000) Light density filters will lower the shutter speed in the bright sunny day to allow you to reduce depth of field in very bright light or to use a wider aperture to stay below the diffraction limit. For example, these filters are necessary to shoot with your fast lenses like F1.4 or F1.2 with aperture wide open for softer and more beautiful bokeh.Middle density filters will help you to add motion blur to the object in the conditions that generally will not allow camera shutter speed to do so.If you are for more creative shots that are based on extremely slow shutter speeds - deep density filters are to be suggested. ND filters like ND500 or ND1000 will help to capture dramatic unreal fantasy world that cannot be seen by the human eye.Color shift issue solutionHOYA offers its own exclusive and wide lineup of ND filters that are branded into PROND EX series for both photographers and filmmakers. PROND EX filters adopt HOYA's clear optical glass that is mounted into a lightweight, precisely crafted aluminum frame. The frame has front filter threads so you can attach additional filters or a lens cap.Thanks to ACCU-ND technology that puts HOYA ND filters far ahead from other brands the image undergoes no negative affect from color shift that may occur due to low-quality materials, poor manufacturing QC, or issues with leaking of the Infrared band of the light spectrum. The last problem is the most important nowadays in photography and videography.HOYA's exclusive ACCU-ND technology achieves equal reduction of the light in visible and IR spectrums. As a result the photographer may not fear any issue with color shift when using HOYA ND filters in different shooting conditions.PROND filters in video productionND filters in video shooting is also an irreplaceable tool. For example, when shooting with Sony camera in Slog mode, ISO cannot be set below 800. To obtain natural motion shutter speed is recommended to be adjusted to frame/rate setting. During the daytime PROND EX 8, PROND EX 64, PROND EX 1000 or its combination (like PROND EX 8 + PROND EX 64) would be necessary to achieve cinematic quality.Combinations of PROND filtersThe choice of ND filters depends on photographer intentions to achieve the desired effect in the image. In case the effect by using single ND filter does not satisfy photographer's vision, combination of PROND EX filters can also be useful. For example, the combination of PROND EX 8 + PROND EX 64 will give the effect equal to ND500 filter, that can be used to express an unreal fantasy world. The combination of PROND EX 8 + PROND EX 1000 will give the effect equal to ND8000, that will allow to capture the surface of the Sun without overexposure with solid color and visibility of the black spots.

Digital multi-coated glass allows a max. surface light reflection ratio of 0.5%. Black-rimmed glass minimizes random reflections inside the frame. Knurling makes it easy to attach and remove the filter. UV absorption filter case. Thin frame design to minimize vignetting even with wide angle lenses. Made in Japan quality The HOYA SPARKLE series is a special cross-effect filter available in a 4-cross and 6-cross pattern. As opposed to conventional cross filters, the HOYA SPARKLE creates only moderately sized beams on light sources while softly enhancing their strength, creating a joyful and fairytale-like atmosphere in photos. From beginners to professionals, the HOYA SPARKLE is recommended for all photographers who want to express themselves in a creative way.A spark inside of usImagine spending a warm spring night with your friends around a campfire, going with your date to a festive illuminated park during a cold winter evening or watching a raindrop calmly running down a flower after a summer storm. These scenes create a special feeling of coziness and ease – a feeling that flickers like a warm spark inside of us.The sparkle effectConventional cross filters may appear with overly long light beams, cluttering and totally overloading your photos. Rather than letting the cross effect take over your photo, the HOYA SPARKLE aims to create a joyful atmosphere subtly through creating only moderately sized light beams. While doing so, the light sources themselves are also being gently enhanced, creating a perfect balance between strength of the light source and length of the light beams. Light sources can be anything – such as stars, light reflecting on water, or sunrays breaking through the crown of a tree.HOYA SPARKLE in astrophotographyThe HOYA SPARKLE 6X is a filter that absolutely shines (literally) in night sky photography. Through taking the light sources of brighter stars and converting them into 6-pointed stars, the SPARKLE series creates a simply beautiful and mesmerizing effect in your photos – creating a new standard for astrophotography.Choose your patternThe SPARKLE series consists of the SPARKLE 4X and the SPARKLE 6X, creating a four-cross pattern and six-cross pattern respectively. Try out both!Soft effectIn the absence of strong light sources in the composition, the HOYA SPARKLE produces a soft effect in your image, creating a dreamy atmosphere. This is especially recommended for portrait, flower and landscape photography. You can further strengthen the soft effect through increasing the focal length towards the telephoto end!Rotatable front frameThrough turning the front frame, you can change the angle of the cross pattern. This gives you the ability to always choose the perfect angle, personalizing your photos even further!Get the best results The cross effect appears from single point sources. Other forms of light sources, e.g., cylinder shaped light like from fluorescent lamps, will not produce an effect. There are also cases in which large light sources prevent the cross effect from appearing clearly. In these situations, try to move further away from the interfering light source and try shooting again. The strength of the light source, the focal distance and the aperture value have an impact on the cross effect. If your image is too dark when shooting illuminations, try increasing the exposure compensation. On the other hand, should the image be too bright, try with a reduced exposure compensation. Cross streaks can be seen better in dark background settings. Also, focusing on the light source makes for a crisper cross effect. Depending on the conditions, a mesh shaped flare will occur (strong light sources and back lighting conditions). Increasing the focal length towards the telephoto end will strengthen the soft effect. Light rays might distort at wide angles. When the aperture is reduced to around f/22, light rays may become dotted. Under circumstances, the HOYA SPARKLE produces a meshed pattern over the blurred parts in your image.

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.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.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.Be aware that when the filter is attached to the lens, the lens cap size becomes one size bigger. So if your lens has a filter thread size of 77mm, you will require an 82mm lens cap. The widened front filter frame has been designed on purpose to avoid vignetting.
