The device, produced by Bullitt Group, takes its name and looks from Kodak's 1941 Ektra camera.
The Eastman Kodak company invented digital photography in the 1970s, but was outpaced by rivals after it decided to focus on its film business instead. The company exited the digital camera market in 2012.

BBC Click's Lara Lewington was one of the first to get hands-on with the camera.
