Fujifilm has shown off its latest X-series camera with interchangeable lenses and retro styling. The X-M1, leaked last week, uses a 16.3-megapixel APS-C X-Trans CMOS sensor, the same X-Trans sensor used in the X-E1, is able to change out its lens with others from the Fujifilm X-Mount range, and is the first to offer Wi-Fi connectivity.
