The SmallRig 3561 multifunctional cage is a multifunctional cage designed for iPhone 13 Pro Max for professional videography, live streaming and vlogging. The compact, snug-fitting cage weighs only 95 g and features 1/4″-20 anti-rotation threaded holes and cold shoes that support accessories such as the 2772 side handle, BUT2664 tripod, 3452 microphone and 3286 LED light. The rear lens cover is interchangeable and compatible with M-mount or 17 mm thread lenses for better image quality. The cable design does not block iPhone buttons and ports and allows the use of radar, ultra-wide-angle lenses and wireless charging. With a quick-lock design, the cage becomes easier to assemble and disassemble, more secure and more stable, and will not accidentally lift up after being locked. The full metal cage, together with the built-in shims, protects the smartphone and prevents vibration and scratches. The cage allows for horizontal and vertical shooting.
