Setting up the housing - Zoom/Focus Knob
The housing is designed to maintain an easy access to the focus knob which is positioned as the top from left hand
controls and zoom knob at the bottom on the housing, this works using gear mechanisms that drive the gear set
attached to the camera lenses.
Majority of the camera lenses have the same ring feature, focus ring on the top and zoom ring at the bottom. But in
some cases (e.g. Canon EF-S 10-22mm f3.5-4.5 USM), both rings are arranged oppositely which will also result in the
housing.
Therefore, this housing also allows you to switch focus and zoom knob positioning in a few steps.
