New BirdCages From LockCircle For Sony a7R II And Sony a7S II

If you use your Sony a7R II or a7S II for production purposes, a BirdCage like LockCircle’s PRO and PRO-S models provide the structure you need to build a full system. Attaching accessories to a camera, especially one as compact as these Sony models, can be problematic at best without a cage. The PRO and PRO-S models feature multiple mounting options and a special design to protect fragile HDMI connections. Solidly constructed, these BirdCages are CNC machined from billet aluminum but are surprisingly lightweight at 4.5 ounces and 7 ounces (PRO and PRO-S, respectively). While both models offer many of the same benefits, the PRO-S is specifically designed for photographers who prefer to use Sony sound capture accessories with the camera’s multi-interface hotshoe.

New LockCircle BirdCage PRO / PRO-S for Sony A7RII And Sony A7SII Cameras!

The new BirdCage PRO and PRO-S by LockCircle are innovative professional cages designed to fit like a glove around the latest mirrorless Sony A7RII and A7SII cameras featuring the exclusive LockCircle “Asymmetrical Design Approach” for right hand camera grabbing and control with the original camera ergonomic feeling.

Designed for comfortable grip and action, leaving on the left side of the camera all the production tools and accessories mounting: a still and film camera without the limitations of other cages.

The BirdCage PRO has the classic LockCircle Twin Baseplate System based on a Ultra-Thin Baseplate and a T-Riser Baseplate, the BirdCage PRO-S (S for Sound) is designed for filmmakers using the original Sony sound capture accessories using the (Mi) Multi-Interface Hot Shoe Compatible System. The BirdCage PRO and PRO-S integrates the new LockPort Flex, and a system of mounting plates and Positive-Lock Mounts for universal lens mounting and precise professional follow-focus work.

The innovative LockPort Flex protects definitely the fragile micro-HDMI output on your Sony A7RII and Sony A7SII from tough production abuse. The LockPort Flex System design introduces new concepts to the original LockPort project adding the freedom to benefit the full-size HDMI output in every direction /position on the BirdCage (cables with drones and gimbals needs special care when setting up to avoid undesired camera movements). The Lockport Flex has three different length cables in kit to reach several output positions and directions.

The BirdCage PRO and PRO-S baseplate has a mounting “receiver”for the Meta-Block, designed for a Metabones “state of the art” mounting/locking, and a IMS-Block for high grade professional Positive-Lock Mounts (PL, Canon EF, Nikon F, Panavision, Leica and M).


Vertical mount of the camera is available and compatible with the LockPort Flex System, and all along the Focal-Plane there are several threads for the (AC) tape measurement hook mounting.

Incredibly lightweight, only 128 grams (4.5 oz.) with the Ultra-Thin Baseplate , 200 grams (7 oz) for the PRO-S.

Available on stock, shipping worldwide.
