XF Lens – New Milestones in Our Quest for Perfection
Each Lens Spurs Your Discovery of New Frontiers of Expression.
The pursuit of image quality excellence has led to the creation
of the XF Lens – the pinnacle of FUJINON optical technology.
We aimed for exceptionally high resolution at maximum
aperture without a decrease in illumination towards the edge
of the frame. We endeavored to maximize aperture F values to
empower you with the brightest, fastest lens possible. We
engineered it to be compact so taking it with you everywhere
would be a pleasure. We expanded lens variations, adding a
versatile zoom lens and ultra wide-angle lens to the family of
premium prime lenses. Now we are writing the next chapter in
the history of XF lenses. Featuring all-glass fabrication of the
Interchangeable F U JINON
11
aspherical lens and other lens elements as well as treatment
with FUJINON's original Super EBC coating to minimize
surface reflectivity, each lens is a masterpiece of optical
technology. Specially developed to extract the full potential of
the XF lens, the X Mount is also found in our flagship X-Pro1
model. Taking full advantage of the mirrorless design, this
innovative mount has a short flange back distance of just
17.7mm, and a wider body opening for deeper mounting of
the lens – up to about 7.5mm from the mount sur face,
improving peripheral light collection and achieving high
resolution all the way to the edges of the image.
With this single versatile zoom featuring a maximum aperture of F2.8 and a
broad focal length range from 27mm* wide angle to 84mm* telephoto, the
photographer can respond to a variety of scenes. Superbly portable thanks to
its compact size, the fast linear motor-driven autofocus and the built-in
functionality of four stops of image stabilization ensure comfortable, confident
shooting even in challenging situations.
