Fuji XF10-24mm F4 R OIS Press Release
FUJIFILM Corporation (President: Shigehiro Nakajima) is proud to announce the launch of the Fujinon XF10-24mmF4 R OIS lens compatible with all Fujifilm X mount compact system cameras.
The new Fujinon XF lens is a 2.4x zoom lens – equivalent to 15-36mm in 35mm format. Its ultra wide to standard focal length capabilities make it the perfect choice for shooting dynamic, high impact landscapes images with maximum detail from the foreground to the far distance. It also comes into its own when shooting interiors, making small rooms look more impressive, while the maximum F4.0 aperture that is available throughout the zoom range, enables handheld shooting even in low light conditions.
Fujifilm’s introduction of the Fujinon XF10-24mmF4 R OIS means its X mount series can now boast (in 35mm equivalent) focal length options ranging from 15mm to 350mm.
Key features on the Fujinon XF10-24mm lens
- Newly designed optical system with 4 high-precision aspherical lenses and 3 extra low dispersion glass lenses which maximize performance of the X-Trans sensor.
- A powerful Optical Image Stabilisation function which boosts the ability to work handheld when shooting in low light.
- Ghosting is minimized by Fujifilm’s unique HT-EBC* multi-layer coating that is applied to all sides of Fujinon lenses.
- An additional newly developed coating has been added to the reverse side of the front lens in the XF10-24 composition to further reduce the ghosting that typically occurs when using deep concave lenses.
- Enhanced resolving power at all apertures when used in-conjunction with an X-series camera** that incorporates a Lens Modulation Optimizer (LMO) function.
- Seven-blade aperture diaphragm that helps to create smooth and round bokeh effects.
- The ability to shoot at an aperture of F4.0 from the lens’ ultra-wide 15mm focal length to its longest at 36mm.
- A minimum working distance of 24cm means that with macro photography you can capture both the small foreground detail and the wider surroundings to give your subject greater context.
- Its high-speed AF is achieved via its inner focusing system which drives smaller lenses in the middle or rear lens groups without moving the larger lenses in the front lens groups
- Thanks to light weight internal lenses and the addition of a stepping motor, the XF10-24mm lens is also very quiet to use.
- With its precision-made, responsive, and finely-tuned metal aperture and focus rings, you are ensured a superb handling experience.

Press Release
HANDEVISION — December 12, 2013
A mutual passion for photography and the art of image capture between two companies’ owner has led two special firms, Shanghai Transvision and German IB/E Optics, to collaborate on an industry-shaking new innovation. By merging Geman high-quality engineering standards with Chinese cost-effective production infrastructure, the new camera lens brand Handevision (“Han” means China in Mandarin and “De” is the word for Germany).
After many months of collaboration between engineering and production teams, final quality control assessments have concluded and the IBELUX 40mm f0.85 high-speed lens, the fastest lens in the world, is nearly ready for release. Available for sale by February, 2014, this lens will be available for Sony NEX, Fuji X, Canon EOS M and Micro 4/3 digital mirrorless camera mounts (MSRP is $2,080 USD).
While risky to start our launch with this ground-breaking high-speed lens, we hope to gain the attention and confidence of photographers around the world with our expanding new lenses. Our mission is to manufacture high-grade lenses of metallic construction with a clean, aesthetic finish. As a new player in the lens market, we believe we can expand our new brand internationally as our engineers, uninhibited by production costs nor by material restrictions, will be free to work creatively in seeking optimal image quality and artistic design.
We are currently working on our next project, the wide-angle IBEGON lens. With Sony releasing the new full-frame mirrorless A7/A7R camera, we have designed a high-speed telephoto APO mirror lens called the IBECAT, named for its sharp image capture, its lightweight construction and fast glass. Additional lenses are in development for full frame mirrorless cameras, including a tilt-shift lens and a compact fixed focal length lens.
We are focusing our efforts at expanding our line of full-frame mirrorless and DSLR detachable lenses in 2014 and are constantly developing ways to satisfy demand of professional photographers for faster, sharper lenses.
