A telephoto zoom designed for use in trying conditions, the Fujifilm XF 50-140mm f/2.8 Lens with 1.4x Teleconverter Kitis a weather-sealed lens spanning the popular 76-213mm equivalent focal length range and featuring a constant f/2.8 maximum aperture. Built for FUJIFILM X-mount mirrorless digital cameras, this fast zoom further distinguishes itself with a sophisticated design, highly effective optical image stabilization system, and a Triple Linear Motor AF system for refined focusing performance.

In regards to the optical design, this lens incorporates five extra-low dispersion elements and one Super ED element, which reduce chromatic aberrations and color fringing for increased clarity and color accuracy. Additionally, a Nano-GI coating has also been applied to elements to alter the refractive index between elements, to minimize surface reflections, and to prevent lens flare and ghosting. Additionally a rounded seven-blade diaphragm contributes to a pleasing bokeh quality when working with selective focus techniques.

Flexible telephoto zoom is designed for APS-C-format Fujifilm X-mount mirrorless cameras and offers a 76-213mm equivalent focal length range.

Constant f/2.8 maximum aperture offers consistent performance throughout the zoom range and excels when working in difficult lighting conditions.

Five extra-low dispersion elements and one Super ED element are used to greatly reduce color fringing and chromatic aberrations in order to produce high clarity and color fidelity throughout the zoom range.

Nano-GI (Gradient Index) coating has been applied to lens elements and alters the refractive index between the glass and air in order to better suppress lens flare and ghosting for diagonal incident light.

An HT-EBC (High Transmittance Electron Beam Coating) coating has been applied to the entire surface of each element for controlling ghosting and flare for greater contrast and color accuracy.

A Triple Linear Motor autofocus system delivers smooth, near-silent performance that is especially beneficial to video applications and when working in noise-sensitive areas.

Complemented by an enhanced gyro sensor and unique series of algorithms, the optical stabilization system minimizes the appearance of camera shake to enable sharper imaging when working with longer focal lengths or slower shutter speeds.

The lens body incorporates 20 distinct weather seals to protect against dust and moisture, and to enable worry-free use in inclement conditions and freezing temperatures as low as 14°F.

Rounded seven-blade diaphragm contribute to a pleasing out-of-focus quality to benefit the use of selective focus and shallow depth of field techniques.

A tripod collar is included for well-balanced mounting and shooting when working from a tripod or monopod.

Compatible with optional XF 1.4x TC WR and XF 2x TC WR teleconverters.

Related Questions and Answers

Q: 1. My new50-140mm lens rattles inside when turned upside down. Is this normal?

A: Yes. Several of the lenses have components that float a bit until power is turned on. It's not a defect and doesn't hurt the lens in any way.

Q: 2. Is there a warranty?

A: Yes, the FUJIFILM XF 50-140mm f/2.8 R LM OIS WR Lens comes with a Limited 1-Year Manufacturer Warranty.

Q: 3. I recently purchased this lens from B&H and now need a quick-release plate for it that will work with my Really Right Stuff tripod setup (RRS TQC-14 tripod with BH-30 LR ball head and B2-40 LR quick release clamp). Suggestions? Thanks!

A: Really Right Stuff L97L multi use plate

Q: 4. Does this lens come with a hood?

A: yes it does

Q: 5. Does anyone know which way the focus works on the XF lenses? Does it pull closer to the right like canon lenses or is it the opposite like Nikon, and some Sony lenses?

A: You rotate the lens' focusing ring to the left to reduce the focus distance, and rotate the focusing ring to the right to increase the focus distance out to infinity. However, you may go into the menu and go to BUTTON/DIAL SETTING FOCUS RING to reverse the direction of rotation of the focus ring.

Q: 6. I just got this lens and I'm noticing it losing focus when zooming, is this a setting I need to change in camera or is it the nature of the lens?

A: This is normal for a still photography lens. Only very high end cinema lenses are truly parfocal (retain focus across zoom range).

Q: 7. does it work with gh5 directly attached or it requires to purchase an adapter for that?

A: It's a Fujifilm XF mount lens designed for any Fujifilm X series camera. It would need an adaptor for other cameras.

Q: 8. Is this lens compatible with Fuji X Pro-1 Camera body?

A: Yes! The lens will work perfectly with the X-Pro1

Q: 9. Is the aperture ring properly designed, continuously variable, or does it click into each stop?

A: I purchased this lens last December. The aperture ring on my lens is graduated in 1/3 stops -- 18 clicks between f2.8 and f22. The aperture ring can be set to an aperture priority automatic ( A ) position past f22. On aperture priority, the lens will meter in fractions of a stop.Hope this information is useful to you.

Q: 10. Fuji 55-200mm

A: 50-140 has much much faster focus, and 50-140 is also weather resistant. But the 55-200 is great for a backpack or a weekend trip if you don't really need a 2.8 lens. Very sharp.
