The SLIK AF1500AC Trigger Ball Head is an innovative and reliable ball head that offers precise control and exceptional stability for photographers. With a substantial weight capacity of up to 8.8lbs (for reference, this can easily support a setup like a Sony a73 with a 70-200 f2.8 lens, which weighs approximately 4.7lbs), and a lightweight design at just 1.2lbs, this ball head is perfectly suited to meet your photography needs. The standout feature of this ball head is its trigger handle. A gentle squeeze of the trigger handle smoothly releases the ball head, allowing you to effortlessly position your camera precisely. Once you have found the ideal angle, releasing the trigger locks the ball head securely in place. Featuring an Arca-type mount, this ball head is compatible with a wide range of accessories, such as the SLIK i-Bracket or standard L-Brackets. The mounting plate offers a complete 360-degree rotation, giving photographers the freedom to capture shots from various angles. Furthermore, it can be locked securely in any desired position. For those seeking a vertical shooting angle, a convenient side slot is provided. In summary, the SLIK AF1500AC Trigger Ball Head is a versatile and user-friendly tool that delivers the precision, stability, and flexibility photographers require.
