Ricoh has introduced the second-generation world positioning system (GPS) unit for its DSLRs that it says gives dependable, high-precision positioning knowledge and guarantees to simplify tracing for astrophotography. The Pentax O-GPS2 is described as a flexible GPS unit to be used with Pentax DSLRs and is the successor to the O-GPS1. This second-generation mannequin guarantees to supply extra dependable and better precision positiong knowledge gathered from the GPS in the US, QZSS in Japan, GLONASS, and Galileo. Ricoh says that when mounted on a appropriate Pentax digital camera physique, the O-GPS2 permits the Astrotracer characteristic, which {couples} the unit with the digital camera’s Shake Discount system to permit it to hint and {photograph} celestial objects. Astrotracer is designed to permit photographers to shoot longer exposures of stars in sharp focus and with out producing “trails.” Ricoh says the brand new GPS unit calculates the motion of stars, planets, and different our bodies utilizing the latitude obtained from the situation knowledge and the digital camera’s alignment knowledge obtained from its magnetic and acceleration sensors. The characteristic then shifts the digital camera’s picture sensor in synchronization with the motion of the objects.
“The ensuing pictures present stars and different our bodies as stable factors moderately than blurry streaks, even throughout prolonged exposures,” Ricoh says. “It additionally makes astrophotography a lot less complicated, because it requires solely a tripod and eliminates the necessity for an extra accent equivalent to an equatorial telescope.” Astrotracer has a number of ranges. Sort 3 is the latest addition and might be discovered within the Ok-3 Mark III digital camera and permits the DSLR to trace celestial objects with out a GPS unit. Astrotracer Sort 1 and Sort 2 are solely out there when the O-GPS2 is used with the Ok-3 Mark III and makes the picture sensor observe the motion of the celestial physique. Sort 2 does so at half the velocity of Sort 1. Ricoh says that photographers can suppress the “movement” of the panorama on the bottom and shoot each the celebs and the panorama collectively in what it describes as “a well-balanced method.” The O-GPS2 data latitude, longitude, altitude, common time, and the route of the capturing location and bakes that info into photographs. Ricoh says that pictures that comprise this knowledge can be utilized to trace capturing areas or evaluation these spots on a pc, making it simpler to kind and file recorded photographs. Ricoh says that the O-GPS2 additionally has a easy navigation operate that calculated the route and distance to a given vacation spot from an energetic place. It additionally has an digital compass operate that shows the digital camera’s route on its LCD monitor with what the corporate describes as “nice precision.”
The GPS unit is weather-resistant to be used in “mild rain” and is powered independently of the digital camera with a single AAA battery. Ricoh charges that battery to final for about 9 hours with a lithium-based battery and about 5 hours with an alkaline or nickel-metal hydride battery. The Pentax O-GPS2 might be out there in late June for $180.
