Lens Cap MENNON SB634 67mm — 67 mm white balance lens cap for white balance calibration

MENNON SB634 is a 67 mm white balance lens cap designed to provide a neutral reference surface for accurate color calibration. The cap screws onto lenses with a 67 mm filter thread and serves as a simple tool for setting in-camera white balance or creating consistent color reference shots for post-processing workflows. It is compact, lightweight and intended for use in portrait, product and studio photography where reliable color reproduction is required.

Advantages

The MENNON SB634 lens cap offers a neutral, uniform surface that helps reduce color casts and improve color consistency between shots. Its 67 mm fit ensures compatibility with lenses that use a 67 mm filter thread, allowing quick attachment and removal. Because it provides a dedicated white balance target at lens level, it helps achieve repeatable camera settings and reduces the need for extensive color correction in editing software.

Suitable for

• Portrait sessions requiring consistent skin tones
• Product photography where true color reproduction is important
• Studio workflows and controlled lighting setups
• On-location shoots where a quick white balance reference is needed

Key specifications

• Mount diameter: 67 mm filter thread
• Function: neutral reference surface for white balance calibration
• Compatibility: fits lenses with 67 mm external/internal thread for filter attachment
• Material: lightweight construction designed for frequent handling (neutral tone finish)

How to use

Attach the MENNON SB634 cap to the lens by screwing it onto the 67 mm filter thread or pressing it into position if the lens uses a snap-on cap form. Point the camera at the capped lens under the lighting you will use for the shoot and set a custom white balance according to your camera’s procedure, or take a reference exposure for later use in raw conversion software. Remove the cap and continue shooting; use the saved white balance preset or reference image during post-processing to ensure consistent color across images.

Usage recommendations

Capture the white balance reference under the same lighting and at the same angle as your subject. Store the cap in a clean, dry place to keep the neutral surface free of dust and smudges. When working with mixed light sources, take multiple references if lighting conditions change significantly during the shoot.
