Getting up and running with the SeeMo 4K couldn't be easier. Mount it on top of your camera with the included 1/4"-20 to cold shoe adapter and insert your iPhone into the spring-loaded mount.

Monitoring with Creative Flexibility

Works great with iPad Pro 13 M4

While the iPad's screen isn't 16:9, the display on the new M4 iPads works quite well with this SeeMo 4K. I'm powering it with a dummy battery and a v-mount, and it's able to power the iPad just fine. Granted, I haven't had the screen brightness up full during a shoot yet. With a lunch break in the middle of your day though, I feel you could top up the iPad and keep it running for a whole day. I'd be interested to know if it can take in feed that aren't 16:9. For example – wireless feeds with Capture One. Perhaps a future update?
