SEAGULL Half-Frame Filter Set for 62mm lenses, model SB1784

The SEAGULL Half-Frame Filter Set for 62mm lenses, model SB1784, is a graduated (half) filter kit engineered for use with lenses that accept 62 mm screw-in filters. Designed primarily for landscape and outdoor photography, the set provides a controlled transition between a denser upper area and a clear lower area to reduce sky brightness relative to the foreground. This helps photographers achieve a more balanced exposure in high-contrast scenes and retain detail in both highlights and shadows.

Advantages

This filter set offers a simple, lens-mounted solution to balance exposure across a scene without relying solely on post-processing. The graduated density minimizes blown highlights in skies while preserving foreground detail, enabling more natural-looking results straight from the camera. The screw-in 62 mm format ensures stable, repeatable alignment and compatibility with any lens featuring a 62 mm filter thread. The optical surface is suitable for use with wide-angle and standard focal lengths where a gradual transition is preferred.

Suitable for

• Landscape photography to balance bright skies and darker foregrounds
• Seascapes and coastal shots where horizon exposure differs from foreground
• Outdoor scenes with strong backlight or high dynamic range

Key specifications

• Filter type: graduated (half-frame) filter
• Mounting: screw-in for 62 mm filter thread
• Intended use: exposure control between sky and foreground
• Optical characteristics: gradual density transition from top to clear bottom

How to use

Screw the graduated filter onto a lens with a 62 mm filter thread and rotate it until the transition line aligns with the horizon or the boundary between bright and dark areas in your composition. Meter exposure based on the overall scene or use spot metering for a specific area, then adjust shutter speed, aperture, or ISO as needed. For panoramas or tilted horizons, slightly adjust the filter position or consider bracketing exposures. Remove the filter when its effect is no longer required.

Usage recommendations

Use the filter when shooting scenes with a clear separation between sky and foreground and where preserving sky detail is important. Combine with a tripod for precise framing and minimal vignetting when using wide-angle lenses. Store the filter in a protective case when not in use to keep the optical surfaces clean.
