You have a phone, you have a DSLR, yet although you love them both equally, the two pretty much never speak. This failure in capturing synergistic value is now at an end, however, thanks to the BlueSLR Bluetooth dongle and its accompanying iOS app. Compatible with iPhones (down to the 3G model), iPod touches (second generation and above), and iPads, this remote control system will let you manually trigger your Nikon
's shutter release from a distance of up to 300 feet. There's also GPS tagging, if you're into that sort of thing
, and a toggle in the app for adjusting exposure length. The app itself's free, though the dongle will set you back a mighty $149. At least it communicates via Bluetooth, which won't require line of sight like Nikon's own IR remotes. Compatibility is set to expand to include Canon DSLRs and Android and BlackBerry smartphones in the future, but if you've already got a D5000 and an iPhone 4 lying around looking wistfully at one another, you can pre-order your BlueSLR at the source link below.
