Boson Lens Focus Tool

  • The Boson Lens Focus Tool allows any Boson lens, which cannot be focused by hand, to be focused by engaging the appropriate slots on the lens barrel such that it can be rotated inside the lens flange.
  • The focus tool has been properly sized such that no vignetting results when it engages the slots on the lens barrel.
  • Note that lens configurations with focal length >25 mm do not require a focus tool since focus is achieved by simply turning the outer barrel of the lens assembly by hand.
  • This product has a 1 – 8 week estimated delivery time. Expediting may be possible. Contact us for more information.
