LockCircle BCA7M2PROSMEGA-BLE Overview

The black BirdCage PRO-S a7 MK2 MicroMega Bundle LockCircle is designed for use with the Sony a7R II and a7S II cameras. It includes a form-fitted camera cage, top grip handle, MicroMega Plus Kit 35, LockPort Flex kit with MicroPort, Topeak LumiTool 7, and Stubby Tool. The cage is specifically designed for use with the Sony sound capture accessories using a multi-interface hot shoe compatible system. Its asymmetric design keeps the right-hand camera grip and controls open for easy operation and handling. The cage features numerous 1/4" and 3/8" mounting threads for accessory mounting. The top grip handle also features 1/4"-20 and 3/8"-16 accessory threads and can support a 15mm rod through its aluminum construction. The handle allows for low-mode shooting.

The MicroMega baseplate Kit 35 attaches to the T-riser plate allowing you to mount this BirdCage onto a 15mm rod system. It is comprised of a mounting baseplate, top plate with safety unlocking system, camera sliding top plate, 15mm rod mount with titanium knobs, and two 35 riser rods. The integrated LockPort Flex sets the HDMI port output in the best position to reach viewfinders and monitors with an improved cable layout on your rigs. The LockPort Flex comes with 3 micro-to-full-size HDMI cables (4, 6, and 8") to offer variety of mounting options. The MicroPort further secures the micro HDMI/mini USB connectors with safety locking, titanium knobs.

The included Topeak LumiTool 7 is an ultra-light, full metal 7-function compact wrench tool with one detachable super bright LED light cartridge for working in the dark. In addition, the straight blade stubby T-handle screwdriver allows you to tighten and loosen the camera tie-down screw. Its ergonomic grip with finger grooves allows for comfortable use, and the fat blade offers a secure grip.

LockCircle BirdCage PRO-S Kit for Sony a7 II Series (Black)

The black BirdCage PRO-S from LockCircle is a form-fitting, professional cage for the Sony a7 II, a7R II, and a7S II cameras. It leaves the grip-side of the camera accessible for unencumbered operation and handling. Similar in nature to the BirdCage PRO model, the PRO-S (with the "S" standing for "sound") doesn't block the multi-interface shoe, allowing users to attach compatible external microphones and audio adapters. For accessory mounting, you'll find numerous threaded holes along the top, bottom, side, and front of the cage. The riser baseplate features a receiver for attaching an optional Meta Block or IMS block to support select Metabones and P+S Technik Positive-Locking System lens mount adapters.
