The Sony A7sII is three and a half-year old. Still Sony felt no pressure to update it so far. Neither Canon nor Nikon managed to release a competitor to this camera. But on May 31 the Sony solo ride will have an end.
It’s rumored that Panasonic will launch a new Cine oriented Panasonic S L-mount camera. I have no specs of this new camera but Panasonic is certainly capable of making a high quality video camera.
The new Sony A7sIII is rumored to be on market this autumn. If the Panasonic S is a good camera for a good value this might forces Sony to price it accordingly. At the end competition is good for us Sony folks too :)
