Clear camera filter Hoya Prond Filter Kit 77 mm

HOYA PROND Filter Kit (77 mm) includes three neutral density (ND) filters — PROND8 (3 stops), PROND64 (6 stops) and PROND1000 (10 stops) — designed to help photographers and videographers control exposure and motion blur when shooting stills or HDSLR video. The kit uses HOYA clear optical glass with a metallic coating on both sides and ACCU-ND technology to provide neutral color balance and reduce light evenly across the spectrum, including the infrared range. Each filter is mounted in a precisely crafted thick aluminum frame to minimise light leakage and maintain accurate exposure and colour.

Advantages

The HOYA PROND kit gives a compact selection of three commonly used ND strengths that cover a wide range of creative needs, from shallow depth-of-field portraits to long-exposure landscape and cinematic daytime video. ACCU-ND coating ensures minimal colour cast while the metallic front-and-back coating reduces IR contamination. The robust aluminium frames prevent light leaks and provide reliable handling on 77 mm lenses.

Suitable for

• Portrait photography with wide apertures to achieve shallow depth of field (PROND8)
• Daytime long exposures for landscapes and cityscapes to blur motion (PROND64)
• Very long exposures to smooth water, blur clouds and remove moving people (PROND1000)
• HDSLR and cinematic video to maintain recommended shutter speeds in bright conditions
• Combining filters for stronger ND effects (e.g., PROND8+PROND64 ≈ ND500)

How to use

Select the ND filter strength based on the desired exposure reduction: use PROND8 for small reductions (3 stops) to allow wide apertures in daylight, PROND64 for moderate long-exposure effects (6 stops), and PROND1000 for strong light reduction (10 stops) to create very long exposures. Screw the chosen 77 mm filter onto your lens thread, ensure it is tightened to prevent light leaks, and compose and meter the scene. For video, set shutter speed appropriate to frame rate and add ND filters to achieve correct exposure without raising ISO. If more reduction is needed, mount two PROND filters together — their combined stops equal the sum of individual stops.

Usage recommendations

When combining PROND filters, check for vignetting on wide-angle lenses and verify colour neutrality before critical shoots. For daytime HDSLR video in log or S-Log modes where base ISO is high, use PROND filters to keep shutter speed at cinematic values while avoiding overexposure.
