When set on a compatible Nikon camera, this device can record the latitude, longitude, altitude, and date/time of image capture. This item appears to be a rare product and is traded at a relatively high price, but since I currently do not have a compatible camera, I am selling it at a junk price with the condition listed as "poor" due to unverified operation. It can be linked with map information to create original maps with images, etc. Connect the cable to the 10-pin terminal or accessory terminal. Included accessories are the 10-pin terminal cable and instruction manual. By connecting with the 10-pin terminal cable, you can record the latitude, longitude, altitude, and UTC (Coordinated Universal Time) of the image capture in the image data. It can be linked with map information to create original maps with images, etc. Also, remote shooting is possible by connecting the MC-DC2 (sold separately).
