See Figure 4.13. Align the large cut-out area
on the lens flange to the bottom of the lens
mount (which has a matching cut-out). The 3
lens assembly slots should align with the lens

set screw in the same location on the lens
mount, preventing the lens from being
installed in the wrong orientation. If the lens flange does not seem to fit into
place over all screws, try rotating the lens assembly in one direction or
another.

With the lens assembly aligned and the screws inserted through the flange, use
both hands to rotate the lens barrel clockwise until the lens mount screw heads
lock into the small end of the lens assembly slots.

Secure the 3 lens mount screws.
