Zoom Sleeve for Tokina 10-17mm f/3.5-4.5 Fisheye Lens (DLM/C)
An interchangeable lens camera demands a housing with
interchangeable lens ports. It couldn't be more simple to change ports
than this system—just press the port on and tighten three thumb screws.
Feel positive reinforcement that the port is secure without any complex
moving parts that can jam or break in a remote location.
