Our favorite wished-for items, though, were those that were imaginative, useful and a good distance beyond the state of current technology--but with that ring of plausibility that characterizes the best science fiction.
Specifically designed to take advantage of the camera's mirrorless design, the X-Mount has a short flange back distance of just 17.7mm made possible by designing the mount ring as thin as 2.5mm.
Additionally, it features a macro switching ring on the lens barrel which instantly shortens the minimum focusing distance to approximately 20cm (from image plane), allowing the camera to capture small, close-up subjects with exquisite detail.
