Hoya - 72mm HRT Circular Polarizer Glass Filter

An exceptional addition to your photography gear, the 77mm HRT Circular Polarizer Glass Filter by HOYA is designed to enhance your image quality by using a state-of-the-art High-Rate Transparency film. This innovative technology allows more visible light to pass through the filter, while effectively filtering the same amount of polarized light. The HOYA HRT circular polarizer filter is capable of transmitting up to 25% more light through the polarizing film. This gives photographers approximately 1/3 stop more light than a standard circular polarizer, offering a significant advantage in low-light conditions. This advanced polarizing film is also utilized in the latest HD LCD TVs, attesting to its superior quality and performance.In addition to its polarizing capabilities, the glass of the HOYA HRT filter also possesses UV absorbing properties. This makes the HRT not just a circular polarizer, but also a combination UV/circular polarizing filter, providing comprehensive protection and enhancement for your lens.The most common use for a circular polarizer filter is to darken overly bright blue skies in outdoor photography. However, it also has the ability to reduce or eliminate reflections from non-metallic surfaces such as glass and water. By simply rotating the outer ring of the filter, you can control the degree of effect, which can be observed directly through the filter or through the viewfinder when it's mounted on a camera.Produced by HOYA, the world's largest optical glass manufacturer, this filter is made to the highest specifications, ensuring compatibility with almost every camera and lens manufacturer. As the world's largest filter manufacturer, HOYA guarantees top-tier quality and performance with every product. This 77mm HRT Circular Polarizer Glass Filter is no exception, promising to elevate your photography to new heights.

The must-have filter in every photographer’s camera bag, Hoya’s NXT Plus 52mm Circular Polarizer has 10 layers of Hoya’s patented anti-reflection (AR) multi-coatings so your images show improved contrast, color and sharpness. The filter applies a waterproof top-coat to Hoya’s polished smooth "Clear" glass for easy cleaning of dirt, smudges and water. The polarizing film is optical thin with a filter factor of 1.72 (less than 2 stops) for faster AF and improved viewing over standard PL films. Hoya’s high quality polarized glass is mounted into a precision milled aluminum slim frame, making it lightweight and perfect for all of your lenses including super wide-angle lenses. Despite the slim profile the filter includes front filter threads so you can attach additional filters or your protective lens cap. Polarizers do one thing: Remove Reflections. Think sunglasses for your lenses. By removing reflections, you reveal the color, texture and detail beneath. So, leaves are greener, skies are bluer, and the beautiful rocks at the bottom of that secret mountain lake are revealed. CRPL’s are also great for removing reflections from car windows, and painted surfaces. Depending on the lighting conditions the effect can be dramatic or subtle but it never hurts to pop it on and give it a try. Circular polarizers are easy to use too. Once attached to your lens simply rotate the outer ring of the filter while looking through your viewfinder or screen until you achieve the right amount of reflection control. When the colors and detail look right, take the picture.

After a unique collaboration between Hoya and esteemed wildlife photographer and conservationist B. Moose Peterson of Wildlife Research Photography, the 52mm Warm Circular Polarizer Glass Filter was born. This high-quality filter ingeniously combines the functionality of a polarizer with the warming effects of an 81A filter. For decades, photographers have relied on polarizers to eliminate reflections from non-metallic surfaces such as water and glass. They are also instrumental in darkening blue skies to enhance contrast in landscape photography. However, using traditional linear polarizers with today's auto-focus cameras, which often employ a split beam metering system, can lead to exposure errors due to their light absorption properties. This is where our durable and effective circular polarizer filter comes into play. It delivers the same optical effect as a linear polarizer, but without causing exposure issues with modern metering systems. A common side effect of both linear and circular polarizers is that they tend to "cool down" the overall color balance of a scene, often resulting in a slightly bluish tint. Our versatile 52mm Warm Circular Polarizer Glass Filter addresses this issue with the addition of 81A glass. This corrects the color temperature, restoring the scene to the original 5500K color balance ideal for daylight film. The 81A glass not only creates a more pleasing and warm color balance for the entire scene, but the circular polarizer also increases color contrast and reduces the effect of atmospheric haze. Easy to use and highly effective, this filter is a must-have tool for photographers looking to capture stunning, high-contrast images in a variety of lighting conditions.
