About this item

  • 【FORMFITTING FULL CAGE】SmallRig A7S III Cage 2999 maintains access to the camera's controls and hot shoe. Made of premium aluminium alloy, the cage is a solid piece of metal that is highly resistant to oxidation and stands the test of time.
  • 【PERFECT PROTECTION】The cage incorporates an anti-twist design with an M2.5 screw fixed to the strap hole in addition to the 1/4"-20 camera mounting screw so your camera can't move around in the cage. SmallRig Cage 2999 also incorporates an anti-twist design with padding on the base to protect the camera from scratching.
  • 【MULTIPLE MOUNTING POINTS】In addition to one cold shoe mount and multiple 1/4"-20 and 3/8"-16 threaded holes, this formfitting aluminum cage features several ARRI-style mounts for preventing accessories from twisting when mounted on the cage. It also comes with a built-in NATO rail on the left of the cage. Mounting holes on the front allow mounting a separately available lens adapter 1764.
  • 【RECOMMENDATIONS】The cage is compatible with SmallRig universal accessory system. You can attach SmallRig Wooden Side Handle 2093 for hand-held shooting, and SmallRig Cable Clamp 3000 to protect the HDMI cable and port. ARRI-style mounts on the top and side are provided to attach SmallRig ARRI Locating Handle or SmallRig Ball Head Magic Arm.
  • 【SWEET DESIGN】Lightweight design with only 200g. Strap holes are included to add a separately available wrist strap or neck strap to your rig. Besides, with built-in magnetic suction design, the included Allen Wrench is ready to use without fear of loss.

EXCELLENT! FITS SONY A7IV LIKE A GLOVE

EXCELLENT! FITS SONY A7IV LIKE A GLOVE
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

    Absolutely incredible. Pretty much the best thing I could have bought for my camera. The build quality is excellent. It has a ton of mounting points, and in general just leaves no limitations for how to build my rig. I’ve shot 30+ weddings with this, and it even saved my camera once when I knocked over my gimbal by accident. Just a fantastic investment.

    5.0 out of 5 stars FITS A7IV LIKE A GLOVE!
    Reviewed in Canada on December 11, 2024
    I recently bought the A7IV and wasn't thrilled with the Smallrig cage I initially chose. It was bulkier and more expensive than I preferred.

    After some research, I found the Smallrig 2999 model, and it's been a perfect fit. It’s similar to my other Smallrig cages in terms of design, but at least $30 cheaper than the previous one. One key feature I really appreciate is that it doesn’t have a battery door trap, so accessing the battery is quick and easy—no need to open multiple doors. It fits like a glove, providing the same reliable protection I’ve come to expect for my Sony cameras.

    I highly recommend this cage for both the A7IV and A7SIII!

    Great cage for Sony A7Siii, some reviews mention not being able to hit the record button with cage on. I agree I wish it was designed a little better, but over all great cage for the price. You can still manage to hit the record button but I changed my trigger button on camera to a more accessible area.

    5.0 out of 5 stars I absolutely love it for my Sony a7 IV!
    Reviewed in Canada on October 27, 2022
    Verified Purchase
    The cage fits perfectly on the Sony a7 IV and feels like it is an extension of the camera when strongly attached to it. It is a bit challenging to put around the camera the first time but once you figure it out, it is really easy to do.

    I mainly use it to be able to shoot vertical video on my Ronin Sc and it works like a charm for this usage. There are many places to screw accessories to the cage, like an external monitor or a microphone. The rig even comes with a magnetic screwdriver that sticks under the cage and is always useful to install the camera or accessories on it.

    I really like this SmallRig cage and would recommend it to anyone who is looking for this type of rig.

    5.0 out of 5 stars 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.
