CamFi is an alternative wireless controller for your Nikon or Canon DSLR

CamFi is a new option for those photographers looking to control their Nikon or Canon DSLR wirelessly. The device mounts on the hot shoe of compatible DSLRs and creates a Wi-Fi network that you can connect to using a PC or Mac as well as Android and iOS mobile devices. At $130 CamFi is priced well below manufacturer-provided options for high-end DSLRs.
