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.

Fortifying Sony ZV-E1 Connectivity with Style!
The SMALLRIG 4K HDMI Adapter has proven to be a game-changer in my Sony ZV-E1 setup, offering a more robust solution and reinforcing the fragile HDMI ports, especially when integrated into a SmallRig cage. The innovation of this adapter becomes apparent when dealing with the notoriously delicate HDMI ports on the Sony ZV-E1. 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. This feature alone has saved me from potential damage, offering peace of mind during hectic shoots. 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. Say goodbye to HDMI port worries and embrace a more solid and reliable solution with this outstanding SMALLRIG adapter. Highly recommended!

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.

very cool
This one is major I wish I tried this earlier. Kind of makes me hate smallHD brand for their stingy and elitist cabling but here we go I could resolve it. Still hating sony alpha though 😂 Good image but the pain of horrible menus and the small body etc I can’t love it after used canon body as my first.

This is a must have for your cage setup!
This is a must have if you have a camera cage! It means you can leave this plugged in all the time and use a full size HDMI cable! No more worrying about micro hdmis breaking or snapping!

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.

Con la lente di 50mm la camera è a 330cm e mi serviva una soluzione più robusta HDMI rispetto alla porta mini HDMI della Sony ZV-E10. Cavetto Perfetto e si avvita al rig, se fosse stato più lungo di un paio di cm ancora meglio. Consiglio.

Le câble est trop court et le micro HDMI est très fragile. Je l'ai plié après seulement 30 minutes d'utilisation ! J'ai dû acheter un serre-câble, car l'utiliser sans est inconcevable.
