  • Based upon a 3d printed frame, the Radial Stylus uses a bearing to turn a stylus tip on your smartphone screen. This rotation can accurately control the focusing page of the amazing IOS app Foolcontol (by Mikael Lubtchansky).
  • Eight magnets allow the unit to divide in half; allowing the user to access a full screen view of the phone in a split second.
  • A carved Bubinga wood grip gives a pleasing texture and increased ergonomics, helpful for those long shoot days. The finger grooves on the grip are large enough to function properly with winter gloves.
  • A silky smooth bearing is embedded into the frame to provide a consistent and accurate rotation for the stylus tip.
  • The back of the unit features a captured 1/4" 20 stainless steel thread which can be used to mount the unit to camera rails, camera bodies, arms, stands, clamps, rosettes, or pretty much anything with a 1/4" 20. The same threads can be used in hand-held configuration for attaching the included Lanyard Loop Attachment, which provides a mounting point at the bottom of the phone for connecting a lanyard.
  • Sadly, not every production can afford a full FIZ hand unit. The mechanical assistance and ergonomics that the Radial Stylus provides is very helpful but will never replace a real wireless follow focus. At times the ios device may ignore the stylus. Momentarily touching the top of the stylus housing or top magnet will wake it back up.
  • IOS device and Foolcontrol app are not included.
