Still longing for a decent camera on your iPhone? All you need's an app and a Canon dSLR and the dream is yours. Well, not exactly, but OnOne Software's DSLR Camera Remote application lets your iPhone or iPod Touch control most Canon dSLRs going back circa the 20D.
Announced in mid-May but available now, the system is a combination of two pieces of software: the free DSLR Camera Remote Server application, which runs on a Wi-Fi-enabled host computer, and either DSLR Camera Remote Professional ($19.99 with an introductory price of $9.99) or DSLR Camera Remote Lite ($1.99), both of which are available via iTunes or the iPhone App Store. Basically, you tether the camera to the host system and use the iPhone/iPod to communicate with the camera via the computer over Wi-Fi.
The Lite version looks pretty bare bones: it can fire the shutter, show the image, and tell you battery status and number of photos remaining. The pro version supports Live View (assuming the camera does); lets you adjust shutter speed, aperture, exposure compensation, ISO, and white balance; choose quality; and zoom during review. It also adds intervalometer capability.
According to the company's blog, "For those of you who are Nikon shooters and are wondering 'Hey, why is this Canon only?' the answer is: 1. Because most of us here have Canon cameras; and 2. This is our first iPhone app and we're not sure how well it will be received." So if you want a version for your Nikon, Olympus, Sony, Pentax, or other model, head over there to request it.
