The SmallRig Pro Mobile Cage for iPhone 11 Pro (17mm Threaded Lens Version) - Model 2775 is a premium, form-fitting aluminum protective housing engineered to transform the iPhone 11 Pro into a professional mobile filmmaking and vlogging platform.

Unlike standard plastic phone cases, the 2775 is an architectural metal exoskeleton. It protects the phone chassis from drops while acting as a rigid structural hub for attaching cinema glass, external microphones, LED video lights, and multi-axis handles.

Key Engineering and Structural Features

  • Anodized Aluminum Construction with Shock-Absorbing Pads: The entire cage is CNC-machined from high-strength aluminum alloy, protecting the smartphone from high-impact damage. The interior cavity is lined with soft, custom-molded rubber and EVA padding to absorb shock and prevent the cage from scratching the phone's glass and steel exterior.

  • 17mm Threaded Optical Lens Plate: Built directly into the rear camera cutout of the cage is a mathematically aligned 17mm threaded lens mount baseline. This enables mobile cinematographers to screw premium anamorphic, wide-angle, or macro lenses (such as those from Ulanzi, Sandmarc, or Kase) directly over the iPhone’s native lenses with zero frame play or alignment drift.

  • Quick-In / Quick-Out Dual-Lock System: The cage uses a toolless, quick-acting pop-lock sliding door mechanism. Filmmakers can press the mechanical latch, slide the top door open, insert the phone, and click it shut in under two seconds.

  • Dual Cold Shoe & Cheese-Plate Mounting Array: The frame is a comprehensive mobile rigging layout. It includes two built-in cold shoe mounts (one on the top horizontal frame, one on the left vertical side) alongside multiple 1/4"-20 threaded holes. These points allow you to mount mini shotguns, wireless audio receivers, or LED panels without adding bulky accessory brackets.

  • Ergonomic Handheld Grip Expansion: The side and top 1/4"-20 hole layouts match standard handle dimensions. This allows operators to bolt on a top handle (such as SmallRig SKU 1984) or dual side handles (such as SmallRig SKU 2424) for rock-solid, multi-handed tracking shots and stable mobile panning.

💡 Operational Mobile Production Tips for the 2775 Cage

The Lens Alignment and Weight Distribution Rule: Attaching high-quality 17mm threaded cinema lenses or heavy anamorphic glass over the camera module creates an off-center weight distribution, throwing the phone's balance toward the upper right. If you mount the cage straight onto a standard compact desktop tripod using a single center screw, the setup will feel top-heavy and tilt easily. To stabilize your frame, attach a SmallRig Lightweight Side Handle (such as SKU HSS2424) to the opposite vertical rail. This grip lets you brace the rig with your hand to smooth out walking vibrations and reduce wrist fatigue.

  • Protecting the iPhone Screen Assembly: While the thick aluminum walls of the 2775 cage shield the sides and back of your iPhone 11 Pro, the front screen remains completely exposed to protect the touch interface. Always pair the cage with a high-quality tempered glass screen protector. Ensure the screen protector is installed perfectly straight; if it extends over the curved glass edges of the phone, the tight rubber padding inside the cage can squeeze the edge, causing the screen protector to bubble or lift away from the display.

  • Bypassing Audio Cable Stress Points: When rigging an external microphone (like a Rode VideoMicro) to the top cold shoe of the cage, you must use an Apple Lightning-to-3.5mm headphone adapter to pipe the audio into the phone. Because mobile setups are subject to sudden movements, tether the adapter cable to the side of the 2775 cage using a small hook-and-loop cable strap. Securing the line stops the adapter from bouncing around, preventing popping noises in your audio track and keeping the Lightning port from wearing out over time.

Not the Fetch-Fest I Hoped For
Color: Orange
I had high hopes for the PetDroid Interactive Dog Ball, especially with the newly upgraded features and promises of durable, motion-activated fun. Unfortunately, it didn’t quite live up to expectations for my furry friend. Here’s why I’m giving it 2 stars. Promising Features, Lackluster Results The idea behind this toy is fantastic: a durable, motion-activated ball that would entertain my dog without much effort on my part. The ball is supposed to roll around on its own, keeping my dog engaged and active. However, in practice, it just didn’t capture my dog’s interest. Durability I will give credit where it’s due: the ball is well-made and seems durable. It can withstand some rough handling, which is great for more aggressive chewers. Unfortunately, durability doesn’t mean much if your dog won’t play with it in the first place. Motion Activation The motion activation feature is hit or miss. While the ball does move around as advertised, it didn’t seem to move in a way that intrigued my dog. He gave it a sniff, watched it for a minute, and then walked away, unimpressed. I tried multiple times to get him interested, but he simply wasn’t having it. Lack of Engagement The biggest issue is that the ball just didn’t engage my dog at all. It might be more suitable for a different personality type or breed, but for my pooch, it was a total flop. He’s usually quite playful and curious, so I was surprised by his lack of interest. Final Thoughts Overall, the PetDroid Interactive Dog Ball might work for some dogs, but it was a miss for mine. If your dog is easily entertained by automated toys, it might be worth a try. However, based on my experience, I can’t wholeheartedly recommend it. Pros: Durable construction Motion-activated as advertised Cons: Did not engage my dog Motion activation wasn’t intriguing enough Might be more suitable for specific dog types or personalities If you decide to give it a shot, just be prepared for the possibility that your dog might not find it as entertaining as you hope. For us, it’s back to the drawing board for a more engaging toy.

Pup Loves It, Some Other Notes
Color: Orange
We've had this for about six months and my 75 lb, 14-month-old German Shepherd pup LOVES IT. Her favorite is "Crazy Bouncing Mode." In fact, she doesn't care much for the normal mode. She chews it a lot - even drops it in her water bowl at times - and it's still going strong. This is a great purchase. It's nice hands-off entertainment. Do know that it is heavy compared to a normal ball - if your pup likes dropping it on the ground like mine does, it will land with a hard "thud," even with the included sleeve. Hopefully you don't have downstairs neighbors. Also know that the cover that goes over the charging port is removable and your dog may choke on it if they chew it in just the right manner. Definitely only let the pup play with it while supervised. All in all, great toy.

Perfect for Blind Dogs, Fun and Durable
Size: 2-pack, Style: Duo
My blind dog loves these Chuckit! sniff balls. She can easily sniff them out and plays fetch with them for 20 minutes a day, even running up and down the stairs. The balls are durable, bounce well, and the bacon and peanut butter scent keeps her engaged. I do wish Chuckit! would bring back the version with a tone so we could play fetch outside more easily. Overall, a fantastic toy for dogs that rely on scent and a fun way to keep them active.

My Golden Loves
Size: 2-pack, Style: Duo
My 8 month old Golden Retriever loves these. It is also one of the few products she cannot destroy. They smell as described and she loves to chew them and play fetch when. She can chew these easily without destroying them. Overall good value for the money for my Golden
