Every photographer and shooting situation is different. And that's why there are different SIRUI Ball Heads to choose from. The SIRUI KX Series of Ball Heads is designed for big equipment and heavy loads. From the compact K-10X, with a load capacity of 20 kg (44.1 lb.) to the top-of-the-line K-40X, with a maximum load capacity of 35 kg (77.2 lb.), these ball heads are impressive performers!
Just look at the design and build of SIRUI KX Series Ball Heads and you'll see that their rugged construction and use of aviation quality aluminum will provide many years of professional use.
The SIRUI KX Series Ball Heads have advanced features that provide safety and flexibility. The SIRUI patented safety lock system, with secondary lock release on the Quick Release platform, lets you re-position your camera/lens for proper balance, without worrying that they will accidentally slide off of the platform. The use of Arca-compatible quick release plates allows you unlimited choices and options. (Note: safety lock design not available from other brands)
For maximum performance and flexibility, there are two separate control knobs. One control knob is for the panning base. Having this as a separate function makes adjustments fast and easy, while not affecting other settings on the ball head. The main locking knob has a conveniently integrated friction control knob that lets you set the proper friction for the equipment you are using.
For critical horizontal or vertical alignment, there are three built-in bubble levels on the quick release platform. Important information at the camera position - more useful than on the tripod.
