A handy GPS unit for digital SLR cameras, offering innovative features for effortless tracking and photographing of celestial bodies

RICOH IMAGING COMPANY, LTD. announced the launch of the PENTAX O-GPS2. The PENTAX O-GPS2 has been developed as a successor to the "O-GPS1" (released in June 2011). In addition to GPS in the US, QZSS in Japan, GLONASS and Galileo can be newly received. Simply by mounting the PENTAX O-GPS2 onto the hotshoe of a PENTAX digital SLR camera,* the user can record the latitude, longitude, altitude, universal time coordinated (UTC) and aspect of shooting locations onto captured images. Image files carrying the location data, can be used to track shooting locations and review location data on a PC. The location data stored on such files also makes it much easier to sort and file recorded images. By coupling the location data with the camera’s SR (Shake Reduction) system, the unit offers a range of unique, advanced applications, including ASTROTRACER, Simple Navigation and Electronic Compass.
* Compatible models are the PENTXA K-3 Mark III, KP, K-3, K-5II, K-5IIs, K-5, K-S2, K-S1, K-70, K-50, K-30, K-r, K-01, 645Z, 645D (as of May 2022). All applications will not support all models.

The PENTAX O-GPS2 will be available from June on. The suggested retail price will be € 249,99 / £ 249,99 / 279,00 CHF
