XEquals, a new Canadian company has just launched blueSLR, a combination of bluetooth module and companion app for the iPhone, iPod touch and iPad that enables Nikon DSLRs to be wirelessly triggered from the app. Not only that, it also geotags your photos, writing its GPS location to the EXIF data of your images.
The small module will attach to the following Nikons : D3100, D5000, D90, D7000, D2Xs, D3, D3s, D3x, D200, D300, D300S, and D700. It has a claimed range of up to 300 feet and since it is bluetooth, it does not have to be line of sight. Cost of the module is $149. The app is a free download from iTunes.
It’s currently only compatible with Nikon DSLRs, although they’re working on releasing a Canon version as well.
