The official product photos for the YN43 show the Micro Four Thirds sensor within and a Canon EF mount. The YN43 is compatible with both EF and EF-S lenses.
The rear side of the device features an expanding clip that snugly holes smartphones of different sizes and padding to keep the phone in place without scratching it.
By clipping the attachment onto your phone and linking up via Wi-Fi, your phone essentially turns into the live view screen and “brains” of the camera system. The YN43 provides the sensor, and a Canon lens is mounted to the other end, completing the modular camera.
Screenshots of the free YN43 in the iTunes App Store give an idea of what the system can do. It’s quite simple and features a capture mode and a playback mode. It appears you can adjust important exposure parameters while shooting the camera.
Similar products have been in the market before, examples include the Sony QX1/QX30 and the Olympus Air.
Other details about the Yongnuo YN43, including pricing and availability, have yet to be announced.
