Lightweight BirdCages For Sony a7R II And a7S II


Adding accessories to prepare your Sony a7R II or a7S II for production can weigh down these compact cameras. And if you’re a hacker who likes the DIY approach, you may be putting your gear at risk with loose connections and less than solid construction. At 4.5 ounces (PRO) and 7 ounces (PRO-S), these cages are lightweight and solidly built. At the same time, they are designed to provide multiple options for securely attaching accessories—from monitors to follow focus systems and more. The PRO-S is configured for photographers who prefer to use Sony sound capture accessories via the camera’s multi-interface port but both models offer a number of accessories and configurable options.

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.
