Pentax announces o-gps1 unit for digital slr cameras

News update from the official Pentax website:


GOLDEN, CO. (June 1, 2011)…PENTAX Imaging Company announced the PENTAX O-GPS1 unit designed for recent PENTAX digital SLR cameras. This new, versatile GPS unit tracks both basic geographical and celestial body location data for both earthbound and astrophotography purposes.
Mounted on the hot shoe of select PENTAX digital SLR cameras,* the O-GPS1 unit records latitude, longitude, altitude, and universal time coordinated (UTC) of shooting locations with captured images. Image files with this GPS data may be used to track shooting locations and review location data on a personal computing device. The GPS location data also helps sort and file recorded images.
* Compatible models are the K-5, K-r and 645D (as of May, 2011). Some of the O-GPS1’s functions may not be available when used with the 645D. Compatible PENTAX digital SLR camera bodies must be updated with the latest firmware version for proper O-GPS1 functionality.

In addition to location data, the GPS unit works with the PENTAX Shake Reduction (SR) system to offer unique, advanced applications, including Astrotracer, Simple Navigation and Electronic Compass. Together, the PENTAX O-GPS and associated applications offer several key functions:
• Geotags images for location information on popular photo sharing websites.
• Charts progress of a hike, bike, boat or other adventure trip with interval position tracking.
• A separate, efficient power source will not drain the camera’s battery during GPS operation.
• Supports terrestrial-based Wide Area Augmentation System (WAAS) for highly accurate positioning.
• An Electronic Compass function assists navigation.

The PENTAX O-GPS1 unit will ship in July 2011. It is available for pre-order now on for $249.95 USD. More information is available here:

PENTAX Imaging Company is an innovative leader in the production of a variety of adventure ready digital cameras including weather-resistant digital SLRs and stylish, compact, waterproof cameras, as well as lenses, flash units, binoculars, scopes, and eyepieces. For more than 90 years, PENTAX has developed durable, reliable products that meet the needs of adventurous consumers and businesses. With headquarters in Golden, Colorado, PENTAX Imaging Company is a division of PENTAX of America, Inc.

GPS function records shooting location data
The O-GPS1 mounts easily on the hot shoe of a compatible PENTAX DSLR camera to records the latitude, longitude, altitude, universal time coordinated (UTC) and direction of the shooting location onto captured images. Using mapping software such as Google Earth™, users may recall shooting locations and directions on a map. GPS functionality also helps sort and file-recorded images.
Note: When the O-GPS1 is used in locations where it cannot receive signals from GPS satellites, location data may be in error or missing.

Astrotracer for astrophotography
The O-GPS1offers the advanced PENTAX original Astrotracer function,* which works with the PENTAX Shake Reduction (SR) system on select cameras for tracking and photographing celestial bodies. The unit calculates the movement of stars, planets, and other bodies using the latitude obtained from GPS data and the camera’s alignment data (horizontal and vertical inclinations and aspect) obtained from its magnetic and acceleration sensors. Then, the unit shifts the camera’s image sensor in synchronization with the movement of the object(s).** As a result, stars and other bodies are captured as solid points rather than blurry streaks, even during extended exposures. The unit also simplifies astrophotography by requiring only a tripod and eliminating the need for additional accessories such as an equatorial telescope.
* This function is available only when the O-GPS1 is mounted on a PENTAX digital SLR camera body equipped with a magnet-driven SR system.
** The duration of Astrotracer operation may vary depending on photographic conditions.

Simple Navigation to indicate location data to a destination
The O-GPS1 offers a Simple Navigation function, which calculates the direction and distance to a given destination from the current position. Users may locate destinations using location data stored on recorded images or register/assign destinations by uploading location data created on a personal computing device.*
* At the time of purchase, the O-GPS1 has nine PENTAX international service centers as preset destinations.

Electronic Compass function to indicate and record direction
The O-GPS1 features an Electronic Compass function, which displays the camera’s direction on its LCD monitor with great precision. Using the aspect of geomagnetism detected by its magnetic sensor and GPS location data, the unit indicates the aspect in relation to true north. Users may record directional data on captured images.

Additional important features
• Simplified weather-resistant construction for use in light rain.
• Independent power source (one AAA-size battery) eliminating the need to draw power from the camera body.

Looks really neat for astrophotographers.

For everyone else - not sure if the other features are worth the $150+ price premium over standalone GPS loggers.

Will you also offer some suitable software? Or do we have to buy some 3rd party tools like Touratech? Or do you expect us to use some rather [f-word] web-based services?

Nifty little device.
This will be enticing to those into astro photography.
Based on this forum, there are a number of users here who would benefit.

Everyone will benefit - it will make AP so simple and lightweight that there's no reason not to give it a try
Amusing: Most of the well-know objects like the Orion nebula + surroundings or the Andromeda galaxy are well in range of 200mm or 300mm optics. Lots of other really decent objecs require even less focal length.

What I really want to know is how long the thing will run on a single AAA battery.

If the compass is as wonky as the one in my iPhone, then I hope that feature can be disabled.

nothing, but it was superceded by the K-r so that's where they spent their effort in firmware development to support this new unit.

Doing it yourself isn't that hard. It's certainly cheaper than hiring Manuel to do it.
