## Long description

JJC SB5719 is a compact 2-in-1 Gray Card and Focus Calibration Chart that helps photographers set accurate white balance and fine-tune autofocus. The gray surface provides a neutral reference for exposure and color correction, while the printed focus chart offers targets for AF microadjustments and evaluating sharpness. Designed for both studio and field use, the card is lightweight and portable, allowing quick reference shots and repeatable calibration workflows.
Advantages
The combined gray card and focus chart reduces the need to carry separate tools, saving space in camera bags. The neutral gray panel provides a reliable reference for manual or custom white balance and for post-processing color correction workflows. The printed focus targets enable consistent AF fine-tuning and quick detection of front- or back-focus issues. The compact construction makes it suitable for on-location sessions as well as controlled studio environments.

Key specifications
 2-in-1 design: neutral gray surface plus printed focus calibration chart
 Neutral gray reference for consistent white balance and exposure
 Printed focus targets suitable for AF fine-tuning and sharpness checks
 Portable and lightweight format for studio and field use
 Durable printed surface for repeated use
How to use
Position the gray card in the same light that illuminates your subject and fill the frame with the gray surface when setting a custom white balance in-camera or when taking a reference shot for post-processing. For autofocus calibration, place the printed focus chart perpendicular to the lens at the recommended calibration distance, ensure the chart is well-lit and steady, then use your camera’s AF microadjustment or calibration routine following the manufacturer’s procedure. Repeat the test and adjust until focus consistently lands on the intended target.
Usage recommendations
Keep the gray surface clean and free of fingerprints to preserve neutral color reference; store the card flat or in a protective sleeve to avoid creasing. Use consistent lighting and distance when performing AF calibration, and verify results with multiple shots and different apertures to ensure reliable adjustments.
