LinkCage™ Expansion Cage for Pocket 3/4/4P

I got this expansion cage from KraftGeek to use with my DJI Osmo Pocket 4P.

This cage is black and feels well-made with a full aluminum construction. It opens up with a hinge and snaps securely around the handle of your pocket camera using a spring-loaded latch. The interior surfaces have rubber pads all around to protect from scratches and provide a snug, grippy hold.

In total, the cage provides 5 mounting points for various accessories. On the rear and side, you have cold shoe mounts. On the rear and bottom, you have 1/4” threaded mounts. Also on the rear, you have 2 fold-out prongs for action camera claw mounts.

The variety of mounts is great for various customized setups and being able to attach tripods, selfie sticks, lights, mics, a phone adapter for monitoring, etc.

The pocket camera normally uses its own adapter to provide a single 1/4” threaded mount on the bottom.
This cage is superior in that it grips the camera around the handle body, which is more sturdy and better able to support the added accessory weight and forces from moving the camera around. It doesn’t put all the stress on the camera’s screw adapter and its clips, which can tend to develop a mild wiggle.

The cage adds versatility as you can use it with or without the camera’s mount adapter, with an extended battery grip, etc. It obviously also allows for multiple accessories to be attached at once and at different positions.
It is quick and easy to remove as well, as just the one spring-loaded latch will release it along with all attached accessories.

I don’t have any major criticisms of this cage. It’s well-built and does what you expect from it. If you want a more solid type of mount for your camera along with the versatility of being able to add various accessories, this one does a fine job.

This expansion cage is constructed from aluminum, giving it a solid, high-quality feel while remaining lightweight and compact. The cage includes multiple threaded mounting ports positioned around the frame, allowing for a range of mounting configurations and accessory attachments depending on the intended use case.

The compact design keeps the added bulk minimal relative to the camera unit, making it practical for accessory mounting without significantly increasing overall size or weight. The variety of threaded ports provides flexibility for different shooting setups and accessory combinations.

Overall, this is a well-built expansion cage with solid construction and practical functionality for accessory mounting.

My old mount felt brittle and required unscrewing a tiny thumbscrew every time I wanted to pack the camera away, which got annoying fast.

The side door snaps shut in half a second without any tools, so you can pull the camera out whenever you just want to slip it into your jacket. It weighs 29 grams, meaning my wrist never gets tired holding it up for long takes at the local park. The aluminum gives it a nice textured grip, and having the camera locked in with that latch gives me total peace of mind. Yesterday I popped my mini tripod onto the 1/4"-20 thread at the bottom and clipped my wireless mic receiver to the top shoe, ready to roll in 20 seconds flat.

Mounting my small LED light right onto the cold shoe took all the headache out of low-light recording. The rubber padding on the inside keeps the camera finish pristine, even when popping it in and out constantly.

I just got this expansion cage for my Pocket 3 and it fits well and is super useful (I will be getting the 4P soon but I expect that to fit just fine as well). I actually like wrapping it around the extension or batter pack, instead of the P3 itself so it balances better. The pros are that it is made of durable aluminum alloy with a soft silicone lining that cushions the camera and prevents scratches, it is ultra lightweight at just 29 grams (important if you are carrying a lot of gear) and compact so it does not add bulk, it has a quick release latch for tool free installation, it includes multiple mounting options, 1/4 inch 20 threaded holes for tripods, a 2 prong action camera mount, and cold shoe mounts for microphones and lights, and you can push the mounts back so they sit flush when not needed. The cons are that it fits pretty snugly but the quick release lever is super easy to hit and accidentally release so you have to be very careful when handling it, and I find it generous to call it a cage since it is not really a full cage but more of an adapter mount. For construction and quality, it is all metal with rubber grips, the secure locking design keeps the camera firmly seated, and the build is rugged for everyday use. Overall, despite initially thinking it was pricey, after using it for a day I can see it is super useful for expanding my Pocket 3 setup, and I recommend it for vlogging, travel, and everyday shooting where you want flexible mounting options while maintaining portability.

I really like this cage because it adds a lot of mounting options to the Osmo Pocket without making the camera feel bulky. The aluminum construction feels solid and well made, while the silicone lining gives some extra protection against scratches when installing or removing the camera. Having a cold shoe, 1/4-inch thread, and action-camera style mounts all built into one cage makes it much easier to add a microphone, light, tripod, or other accessories. The quick-release latch is also convenient since you can get the camera in and out without messing around with tools. At only 29 grams, it adds very little weight to an already compact camera setup. I especially like it for travel because I can keep the cage on hand and quickly adapt the camera depending on what I'm shooting. Overall, it’s a simple but very useful accessory for getting more versatility out of the Osmo Pocket.
