The new
Pentax K-1, 36MP, full-frame sensor camera with built in WiFi & GPS, IBIS (in body image stabilization) and sensor
pixel-shift technology sounds really interesting, especially for only $1800.
Their full frame lens selection is lacking, and their new 15-30mm f/2.8 is a Tamron re-branded lens. Like Nikon you can use their DX lenses on the camera with a crop factor or use their older film-era lenses.
Lots of interesting features in the camera but Ricoh will need to ramp up their full frame lens lineup quickly if they want their new full frame to be a success.
