Details and features

As you would expect from William Optics, his eye for detail and practicality is always very high. For example, a Bahtinov mask is incorporated in the dust cap. With this mask you can focus very accurately on the object to be photographed. The handle has a slot into which, for example, a William Optics Uniguide 32 or Uniguide 50 can be slid. The focusing device is equipped with a coarse and fine focus and also has a temperature meter in a button. You screw the necessary FLAT6AIII to the focusing tube (only for photography), as a result of this screw connection you are sure of a straight connection between both parts. This is better than a sliding connection.
