With the wholesale shift to mirrorless cameras (Pentax?) the camera world probably thinks it has finally modernised and cosigned the old flappy mirror technology to history (although my Canon 1D C would like a word).
But now there is a new threat to the high end camera market and this time not from itself.
Sensors in smartphones are getting larger. Much larger.
The progress in the last 7 years is remarkable (as my chart above shows). Smartphones have caught up and surpassed Super 16mm. Is Super 35mm next?
