Hoya 72mm PROND EX 64 Neutral Density 1.8 6-Stop Filter

What sets the 72mm PROND EX 64 Neutral Density 1.8 6-Stop Filter apart is its ability to provide filmmakers and photographers with precise control over the light entering their lens, thereby enhancing exposure control. This is a critical tool for filmmakers aiming to achieve shutter speeds that align with their frame-rate while preserving their desired depth-of-field. For photographers, this filter enables longer exposures or the attainment of a shallow depth-of-field even in bright sunlight.

One common issue with many neutral density filters is the unpredictable "color shift" caused by substandard materials, poor manufacturing processes, and disregard for the infrared band of the light spectrum. This can lead to drastic changes in color shifts as filter density and exposure times increase. However, with the ACCU-ND technology incorporated in this filter, such negative effects are eliminated. This technology ensures equal reduction of light in both visible and IR spectrums, thereby preventing color shift issues under varying shooting conditions.

The 72mm PROND EX 64 Neutral Density 1.8 6-Stop Filter is securely mounted into a lightweight, precision-milled aluminum frame. It also features front filter threads, allowing for the attachment of additional filters or a protective lens cap. This filter is also an excellent tool for shooting videos, particularly when using a Sony camera in Slog mode where the ISO cannot be set below 800. To achieve natural motion and cinematic quality, the use of PROND EX 8, PROND EX 64, PROND EX 1000, or a combination of these filters is recommended.

The choice of ND filters is largely dependent on the photographer's intention and the desired effect in the final image. If a single ND filter does not meet the demands of the situation or the photographer's vision, a combination of PROND EX filters can be used. For instance, combining PROND EX 8 and PROND EX 64 results in an effect equivalent to an ND500 filter, perfect for creating a surreal world. Similarly, the combination of PROND EX 8 and PROND EX 1000 produces an effect equivalent to an ND8000, which is ideal for capturing the surface of the sun without overexposure.
