Pentax released new information for the O-GPS1 module today that’s sure to make K-5, K-r, and 645D owners quite happy. The new hot-shoe mounted GPS unit records latitude, longitude, altitude, and even shooting angle. The built in “Astrotracer” function can even determine stars movements and use the PENTAX Shake Reduction System for better celestial images. The Pentax O-GPS1 will ship in July and is currently available for pre-order at the asking price of $249.99. Please note that the O-GPS1 is only compatible with Pentax DSLR’s that are currently updated to the newest firmware.
