Hoya YPND100077 77mm PROND ND1000 Filter

The Hoya 77mm PROND ND1000 is a 10-stop neutral density filter built for photographers who want to push exposure times into multi-second territory in broad daylight. The headline specification — a filter factor of 1024x, or ND 3.0 — means a scene that meters at 1/250s becomes a 4-second exposure. That's the realm of silky waterfalls, streaked cloud formations, ghost-free cityscapes, and the ethereal motion blur that defines fine-art landscape work. What separates the PROND from cheaper alternatives is Hoya's ACCU-ND metallic coating, which maintains color neutrality across the density range. Many 10-stop filters introduce a noticeable warm or magenta cast that requires correction in post; the PROND delivers files that look natural straight out of camera, saving time in editing and preserving accurate color when shooting in mixed or shifting light.

The filter is constructed with a low-profile aluminium ring that threads smoothly onto 77mm lenses and is designed to avoid vignetting on focal lengths down to around 24mm on full-frame sensors. The multi-coating reduces ghosting and flare — important when you're pointing at bright skies for long exposures. This is a filter for photographers who already own a tripod and understand the workflow: compose, focus, switch to manual focus, mount the filter, calculate the compensated exposure, and shoot. It rewards patience and technique with images that cannot be replicated in post-processing. At 77mm, it covers most professional-grade zooms and primes, and step-up rings extend its reach to smaller-threaded lenses in your bag.
