G Series

The G-series has a main locking knob which is separate from the friction control knob so that it can be more precisely controlled. The structure of the interior is a double bevel locking system which locks the ball in a very strong manner. The four knobs of adjustment (from the base and up, respectively) are the panoramic control knob (smallest), friction controlled knob for fine tuning and adjustment (medium size), ball-locking knob (the largest), and the plate-locking knob at the top.

Some highlights about SIRUI ball heads:

  • Each assembled component of SIRUI Ball Heads is produced by CAM (Computer Aided Manufacturing) - the ultimate in precision manufacturing techniques.
  • SIRUI ball heads are made of aviation quality aluminum alloy 7075-T6 and 6067-T6 for long life and maximum strength.
  • SIRUI uses a special manufacturing technique that produces the support ball with tolerances to within 0.01mm of a perfect sphere. This uncompromising precision guarantees superior performance and smooth operation for any type of 35 mm DLSR or medium format camera system.
  • The panning base is designed with a 360 degree dial. Having a separate panning base lock knob provides greater accuracy for panning and panoramic shooting.
  • The interior locking system in SIRUI Ball Heads uses SIRUI designed double bevel locks for superior locking performance and reliability. Most other ball heads only use a single, less efficient interior locking system.
  • The patented safety lock design, and SIRUI quick release plates, effectively prevent the camera from accidentally sliding off of the ball head. And most quick release plates can be used on SIRUI Ball Heads (Note: safety lock design not available from other brands).
  • The custom anodized surface treatment makes all metal surfaces highly resistant to abrasions and produces a beautiful appearance.
