They’ve taken their original full frame small form factor camera — the RX 1 — and totally upgraded it with many features that Sony a7R II photographers are sure to love!
42 mp sensor
Variable Low Pass Filter (the first of it’s kind)
Built in pop up EVF (with Zeiss T* coating)
Though not inexpensive (around $3300 US) it is sure to be an amazing imaging beast in a small, palm sized camera.
