About Sirui KS Series

With the Sirui KS-40 Low-Gravity Quick Release Ball Head, photographers can experience unparalleled stability and precision in their shooting endeavors. This innovative ball head is designed with a low gravity center, achieved by its unique knob rotation mechanism that securely "hugs" the ball. This design not only enhances the locking force but also minimizes vibrations, making it ideal for long exposure and low-light photography.

The KS-40 ball head is equipped with a friction adjustment feature, allowing it to accommodate a wide range of equipment weights. This ensures stability even when heavy gear is mounted, and once adjusted, the friction level remains consistent for seamless and flexible operation. The compact and straightforward design of this ball head simplifies the shooting process, making it compatible with SIRUI L-324F and ST-224 Series tripods.

Featuring a Quick Release Flip Lock System inspired by the SIRUI Rapid System, the KS-40 allows for swift and effortless installation. The side-loading plate design enables users to mount their equipment with just one hand, enhancing convenience and efficiency. For added security, the dual lock system, comprising a safety bolt and flip lock, prevents accidental dislodging of your equipment.

Included with the KS-40 is the Arca Standard Quick Release Plate (TY-55KS), catering to diverse shooting needs. Additionally, the package includes a 360-degree panning Arca-Swiss plate (KS-55P), which offers horizontal angle adjustments even when the base is locked. This feature, combined with the double notches on the KS-40, supports vertical and multi-angle shooting.

Constructed from strong aluminum alloy, the KS-40 ball head is built to last. It can be mounted on various tripods via the 3/8"-16 threaded hole on its bottom. The 360-degree panorama base, complete with marked increments, assists photographers in achieving precise manual panoramas. The included magnetic Allen key facilitates easy installation and adjustment, ensuring that the flip lock's tightness can be fine-tuned to accommodate any tolerance in the quick release plate.

Overall, the Sirui KS-40 Low-Gravity Quick Release Ball Head is a versatile and reliable tool for photographers seeking stability, ease of use, and adaptability in their equipment.
