Manufactured in Switzerland, by J.P. Graf, Studioball is a high precision engineered ballhead suited for both studio and outdoor photography.  Manufactured from aircraft-strength aluminum,  Studioball comes in two sizes, Standard, and Mini, and are available in either Quick Release or Reversible 1/4 and 3/8 stud configurations.

Features exclusive to Studioball make it an outstanding choice for supporting just about any camera system, from 35mm up to larger 8 x 10 field cameras. Long Lens shooters especially benefit from many of these features:

ï Our new Posi-Lock quick release mechanism (SB-QR) provides that extra bit of  "insurance" that  many photographers have so often wished that they had.  Camera plates, which can be inserted from either side of the quick release mechanism are held in place not only by tightening the quick release  locking knob, but by the addition of a red safety lock device which holds the camera in place, even in case of unintentional loosening of the locking knob.

ï The exclusive ball bearing swiveling pan mechanism (SB-QR and SB-14 ) provides absolutely smooth and vibration-free camera rotation. Long life and reliable function is guaranteed even under the most severe conditions.
 

Other features shared by all Studioball models are as follows:

ï Heavy duty 6 mm body casing.

ï Dual function friction knob, which (A) adjusts relative tension on the ball , and
(B) safely locks the ball head, preventing tipping over of the camera if the main locking knob is loosened inadvertently.

ï Large size main locking knob, which holds the camera in any position, including verticals, providing rock steady support for even the heaviest camera/Tele-Lens combinations.
