Sony had already presented a seemingly revolutionary idea almost 4 years ago at IFA 2014
with the QX1: A minimalist APS-C sensor box for interchangeable lenses, which is operated almost entirely by the smartphone. Even video recordings (but with an extremely low data rate) were possible. But the success failed to materialize, although even the price of 299 euros was not overpriced.

The QX1 was not the desired success for Sony.
For the Chinese manufacturer YONGNUO, however, the idea still seems promising, which is why a very similar concept has now been announced. However, the YN43 named camera has only one MicroFourThirds sensor with a resolution of 4608 x 3456 sensors. Remarkably, it sits behind a Canon EF mount. The reason for this may be that the company does not manufacture its own MFT optics, but has so far already achieved a certain degree of popularity with very inexpensive Canon lens clones (www.slashcam.de/news/single/Canon-und-Nikon-Objektiv-Kopien---Yongnuo-35-und-5-11860.html).
Whether you can also film with the YN43 is still in the stars.
Personal View firmly assumes, screenshots of the very rudimentary app do not yet point this out. YONGNUO itself has published
except product photos also no specs (and therefore no price).
Personally, we are divided. Finally, such a camera could become a
more advanced Blackmagic Pocket Cinema camera, which is controlled by a smartphone. On the other hand, such a concept requires a lot of experience, which is what users want. Whether YONGNUO has a better hand than Sony here, we dare to doubt.
