great value and saves your camera port from damage.
This is a brilliant bit of kit that prevents port damage on your camera. I see this type of adaptor as essential if you use a camera rigged cage and are constantly connecting and disconnecting the HDMI cable, plus the added bonus of the jump up to a standard sized port from the micro HDMI. It's working very well with my Canon R5 to make it easier to use and extend the life of the port. The quality of build and general reliability makes it good value for money.

The SMALLRIG 4K HDMI Adapter not only provides a secure connection but also acts as a protective extension, reducing strain on the camera’s original port.

The 4K@60Hz capability ensures that my video output remains crystal clear and smooth, meeting the demands of high-quality videography. The compact design of the adapter seamlessly integrates with my SmallRig ZV-E1 cage, creating a sleek and professional appearance without sacrificing functionality. One noteworthy aspect is the durability of the SMALLRIG adapter. The build quality is top-notch, and it feels like a solid and reliable addition to my camera rig. The gold-plated connectors further contribute to stable signal transmission, eliminating any worries about signal dropouts during critical recording moments. Integration with the SmallRig ZV-E1 cage is seamless, showcasing thoughtful design synergy between the adapter and the cage. The adapter fits securely, aligning perfectly with the overall aesthetics of the SmallRig setup. In conclusion, the SMALLRIG 4K HDMI Adapter is a must-have accessory for Sony ZV-E1 users, especially those utilizing a SmallRig cage. It not only fortifies the HDMI connection but also adds a touch of professionalism to the rig.

Great product.
Used it a ton, still works like new, looks like a really high quality, both the cable and the unit itself. Love the minimalist size and as you might guess, it's easy to use.

A good solution to Sony's bad design
HDMI type-A to type-D adaptor. The Sony A7Cii has quite a few design flaws, one of them is the inclusion of a micro-HDMI port - it's very vulnerable and just waiting to get ripped off the mainboard. Fortunately Smallrig make this solution and it works very well, allowing full-size HDMI cables to be attached and removed with zero stress to the mini port itself. Note that you also need a camera cage to attach this to - many of which also have a cable clamp which further strengthens the connection. I do wish there was a version with a right-angle HDMI-D plug so the cable wasn't sticking out so much.

Bent on the 2nd day, but I will buy another one.
I really wanted to love it. However, due to the using it in the field on a project these last 3 weeks the connector is already bent due to a small knock on the 2nd day. Luckily it didn't get stuck into my Canon R5 (That would be an expensive repair). This is not the fault of Small Rig, it's the fault of Canon using a micro HDMI on their professional camera. I will buy another one as it's still the best one out there and try to be more careful, but it is not easy being careful in the field on projects.
