Installing Zoom Clamp/Sleeve on Type 2 Lenses (cont.) Before installing the lens port and checking operation, make sure the teeth on the Gear Sleeve mesh with the teeth on the housing Drive Gear, shown below. When the port is installed, pages 15 & 16, it will lock the Gear Sleeve in place. After installing the port, rotate the housing Zoom Control Knob to see that the Gear Sleeve is properly rotating the Lens Zoom ring. Manual Focusing Note: Ikelite DSLR housings are designed for auto-focus DSLR cameras and lenses. Manual focusing is not recommended. In some cases, if you desire to manually focus a lens, the zoom clamp must be moved onto the lens Manual Focus Ring and you must use the housing zoom control knob to manually focus. This will result in loss of zoom capability. IKELITE Figure G Mesh Gear Sleeve teeth with Black Housing Drive Gear 14
