Our current major advertiser, Pentax, has just announced the O-GPS1 unit, a versatile, weather-resistant GPS unit that tracks both basic geographical and celestial body location data for earthbound and astrophotography purposes.
Mounted on the hot shoe of select Pentax DSLRs, 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. The O-GPS1 works on the K-5 and the K-r, and most function work on the 645D.
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.
The O-GPS1 will ship in July 2011. It is available for pre-order now at the Pentax Webstore for $249.95.
ADDENDUM (request for information):
Dear Folks, Dear Mike,
I was looking for a technical paper online that would give the limits (horizontal, vertical, rotational) of the sensor shift in the Pentax K-5. If I knew that, it'd be simple geometry to figure out what it could do for astrophotography, in principle (practice is always another matter). Anyone reading this have that info? Please email me: firstname.lastname@example.org
