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 Pentax K Mount Lenses to Fujifilm X Mount Digital Cameras from Novoflex makes it possible to mount a Pentax K 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. The adapter features an integrated aperture control ring and can be used with lenses that do not come with manual aperture control ring.
