The idea of streaming liveview from your phone to your camera is not a new one. I’ve been doing it over USB and WiFi now with my Nikon DSLRs to qDslrDashboard for a while now. Other solutions, such as the TetherTools Case Relay. But, both of these systems are quite limited. You have to have one of a set list of specific cameras, for a start.
This device, called LukiLink, though, actually gives your phone HDMI capture abilities. So, you can use it with any camera that has an HDMI output. You can use it to monitor, record, and even live stream your DSLR, mirrorless or other camera’s output. The product is currently about a third funded on Kickstarter with 23 days to go. But if it can deliver on its promise, it looks fantastic.
