RICOH NEW GZ-1 Rumor | GB LIFE STYLE
"Bridge camera from Ricoh, Pentax and Samsung, based on the DA15 Limited, and with a Ricoh-designed and branded body (GRD-based) with Samsung's 14MP CMOS sensor, to become a compact body with exchangeable lenses, GZ-1.
the web site obtained pictures of engineering samples - compared with GRD and GX, it retains the two dials, is slightly larger, and added a small top LCD. 3" 0.9MP back LCD, internal flash and a red LED AF assist light. Tv mode is added. There's a lens release button at the front, which can be paired with compact interchangeable lenses.
In the future there'll be a PK Mount adaptor, much like how M4/3 uses existing 4/3 lenses (it's unknown whether it supports AE and AF). It's rumoured that this move can diversity Ricoh's product range, increase sales and market share of Pentax lenses, and expand Samsung's territories on sensors and related electronics. Availability: TBA."
