Excellent Camera Cage for Sony a7S III
Reviewed in the United States on October 17, 2023
Verified Purchase

I recently purchased the Smallrig Camera Cage for my Sony a7S III, and I couldn't be happier with my decision. This product has completely transformed my shooting experience and added tremendous value to my videography setup.

The build quality of the Smallrig Camera Cage is outstanding. It's sturdy, durable, and fits my Sony a7S III perfectly. The cage provides excellent protection for my camera while offering a plethora of mounting options. I especially appreciate the thoughtfully designed layout, which allows me to attach various accessories such as a microphone, monitor, and lights without any hassle. The cage's design doesn't obstruct any of the camera's essential functions, which is crucial for capturing spontaneous moments efficiently.

The attention to detail is evident in every aspect of this camera cage. The precise engineering ensures a snug fit, giving me confidence that my camera is secure during intense shooting sessions. The ergonomic design also enhances the grip, making it comfortable to hold for extended periods. Additionally, the numerous 1/4"-20 and 3/8"-16 threads provide endless customization possibilities, allowing me to tailor my rig according to my specific needs.

Another standout feature is the quick release plate, which allows me to switch between handheld shooting and tripod use seamlessly. This feature is incredibly convenient, saving me valuable time during my shoots.

In terms of value for money, the Smallrig Camera Cage is unbeatable. Considering its high-quality construction, versatility, and the enhancement it brings to my filmmaking endeavors, it's a worthy investment for any Sony a7S III user. The cage is also easy to install, making it accessible for both beginners and experienced videographers.

In conclusion, the Smallrig Camera Cage for Sony a7S III is a game-changer for any filmmaker or content creator. Its exceptional build quality, versatility, and thoughtful design make it an indispensable addition to my gear collection. I highly recommend this product to anyone looking to elevate their filmmaking experience.

The media could not be loaded.

I’ve had about 5 different small rig cages for several camera models. This is the lightest and most shape confirming one. Has a built nato rail on the left and the cage is designed so you can add handles, triggers and just get really creative in the way that you can set your rig to hit the ground running!

I own both an A7r II and III. Purchase the cage because it was alot less than the one advertised for the A7r III.

Reviewed in Canada on February 17, 2022

For anyone looking for an alternative cage for their new Sony A7IV then this is it! ...No one had written a review yet whether this will fit the new A7IV body. It does! Perfectly. I was hesitant at first, but thought I'd give it a go because the cage is set up more ergonomically and efficiently, in my opinion, than the main SmallRig cage advertised specifically for the A7IV. Body dimensions between the A7SIII and A7IV vary only by millimetres. Build is solid! Anti-twist lock lines up perfectly along with bottom bolt. Rear of camera sticks out a little by less than a centimetre but almost unnoticeable. Hope this helps anyone looks for more options! Good Luck
