Adjust zoom, focus and iris

General
Zoom controls the size of the projected image.
Focus controls the sharpness of the projected image.
Iris controls the contrast and focus depth of the image. Decreasing the iris stop will increase contrast and image depth, at the same
time as it decreases brightness.
Lens zoom, focus and iris adjustments are done manually; they are not motorized.
Not all lenses have zoom or iris control. The table below shows what controls are available per lens.
