Add GPS Tracking to Pentax Digital SLR Cameras

Pentax will release a GPS unit, named O-GPS1, in July. This $250 gizmo attaches to the hot shoes of certain Pentax digital SLRs. The O-GPS1 can note altitude, latitude, longitude, and universal time coordinated (UTC) and bundles the data with each image you shoot.
As of last month, there are only three compatible cameras: the K-5, K-r, and 645D. No doubt support will grow as Pentax releases new cameras.
The O-GPS1 also uses the capabilities of these cameras’ built-in shake reduction system to go beyond simple tracking:
• Geotags images for location information on popular photo sharing websites.
• Charts your progress with interval position tracking.
• Supports terrestrial-based Wide Area Augmentation System (WAAS).
• An Electronic Compass function assists navigation.
