Heliopan 62mm RG 780 (87) Infrared Filter

62mm Infrared Filter for Digital and Film

The Heliopan 62mm RG 780 (87) filter is designed for infrared photography with digital cameras and specialised infrared film. It blocks all visible light up to 780nm, allowing capture of subject matter not visible under normal conditions. The nearly opaque glass requires disabling auto-exposure and autofocus for greater control over results. This filter suits photographers exploring near-infrared creative work.

Upgrade from Standard Visible-Light Filters

Moving from a conventional UV or clear protective filter to this infrared filter enables a fundamental shift in spectral recording rather than a simple optical improvement. The jump is worth it when the goal is to render scenes in wavelengths the human eye cannot perceive, such as foliage appearing bright white or skies turning dark. It does not serve buyers who want more storage or builders needing a second card for conventional colour photography.

Practical Limits of 780nm Cut-Off

The 780nm cut-off means the filter transmits only near-infrared radiation, making the viewfinder extremely dark and exposure highly variable with ISO and lighting. Auto-exposure meters and phase-detect autofocus systems become unreliable, so manual operation is essential. The filter factor cannot be fixed to a single number, requiring test shots and bracket sequences for consistent results. Users without manual controls on their camera will find the filter impractical.
