One of the most appealing aspects of mirrorless cameras like those of the Fujifilm X series is the availability of a wide range of compatible interchangeable lenses, including non-Fuji lenses. The Adapter for M42 Mount Lenses to Fujifilm X Mount Digital Cameras from Novoflex makes it possible to mount a M42 mount lens to your Fujifilm X-Pro1, XE-1 and XM-1 Mirrorless Digital Cameras. This precision mechanical adapter does not transfer functions from the camera to the lens, such as automatic focus, however automatic exposure metering in aperture priority and stop-down metering is possible. The lens will focus to infinity using this adapter.
