Ricoh has just unveiled its Pentax K-3 II, a semi-pro DSLR that boasts improved image stabilization system that implements a Pixel Shift Resolution feature, minimizing false color. In terms of specs, the camera mimics its predecessor’s 24 megapixel sensor, 27-point AF system and durable construction. However, updates include a sensor-shift IS and 4.5 stops of shake reduction to complement the built-in GPS and gyro-sensor based panning detection and automatic horizon correction. Unfortunately, this iteration no longer includes a built-in flash. The camera will be available in May for a retail price of $1,100 USD.
