The Accsoon SeeMo 4K HDMI Smartphone Adapter can bring you a lot of better budget and a lot more freedom when you team it up with your iPhone which you previously owned. If mounted on the top of your camera with the Accsoon SEE app, your iPhone will offer you a lot of shooting monitors, such as focus assist, zebra, false colour, histogram, audio, metadata… and so on. With a standard iPhone connection, your beautiful footage can be published online or streamed in 4K in a much quicker way compared with a common monitor due to the internet available on your iPhone, and by using an optional Sony NP-F or compatibility battery, your Accsoon SeeMo 4K HDMI Smartphone Adapter acts as a power supply or even a charger to your iPhone so that it will never let you down during a shooting day.

Easy Setup

Getting up and running with the SeeMo 4K couldn't be easier. Mount it to the top of your camera with the included 1/4"-20 to cold shoe adapter and insert your iPhone into the spring-loaded mount. Then, connect the SeeMo 4K to your camera via an optional HDMI cable and your iPhone to the SeeMo 4K via the included Lightning or USB-C cable. Finally, download and install the Accsoon SEE app.

Monitoring with Creative Flexibility

Monitoring tools provided by the SEE app include focus checking, waveform display, zebras, anamorphic video support, grids, and auto level monitoring. Additionally, you can apply custom LUTs directly to footage or burn LUTs into Log-encoded footage for added creative control.

Seamless File Transfer

With a built-in SD card reader, you can seamlessly transfer files between your iPhone and SeeMo 4K with an optional memory card. You can then use that SD card on a laptop for post-processing, backup, and transfer as an alternative to dealing with Wi-Fi or Bluetooth.

Add an Accessory

The SeeMo 4K features a USB-C port for outputting 5V/2A of power and a top-mounted cold shoe. This lets you mount and power an optional accessory, such as an LED light or external microphone, further enhancing the quality of your content.
