Pentax’s Optio WG-1 GPS point-and-shoot satisfied geotaggers out of the box, but owners of its K-5, K-r and 645D DSLRs have had to make do with third-party taggers like the PhotoTrackr or Eye-Fi . The new hotshoe-mounted O-GPS1 module fixes that oversight by recording latitude, longitude, altitude, Coordinated Universal Time and shooting angle. Everyday snappers might find an extra hotshoe attachment cumbersome, but astro-photography enthusiasts could well be enticed by the device’s interesting “ASTROTRACER” function. This helps you take clearer photos of celestial bodies by using the in-built sensors to calculate a star’s movement and then employing the camera’s shake reduction system to compensate. Sounds clever, but be advised: this module is only for Pentax DSLRs — and only for very specific models at that. You’ll get full functionality with the K-5 and K-r cameras, and geotagging (no ASTROTRACER) with the 645D. Oh, and you’ll need to make sure your camera’s firmware is up-to-date. Peer carefully through that lens and you’ll see the O-GPS1 heading for a July landing, priced at $250.
