Specification

Fujifilm Fujinon XF 50 140mm Lens (7)This 2.8x telephoto zoom lens for Fujifilm X-series interchangeable lens cameras provides a field of view equivalent to a 75-210mm lens on a 35mm camera, and sports a fast constant f/2.8 maximum aperture, optical stabilisation and costs around £1200. This lens also sports a weather-resistant construction. In this review, we'll take a look at how this eagerly awaited lens performs.

Fujifilm Fujinon XF 50 140mm Lens (2)

The  combination of high-quality plastics and metal used in the construction of this lens, has resulted in robust build, whilst striking a very good compromise between build quality and weight. At 995g it isn't as heavy as you may expect.  As a result it compliments the Fujifilm X-T1 used for testing very well.

Focusing and zoom are performed internally, so the filter thread does not rotate during operation and the lens does not extend. As a result, the 72mm filter thread does not rotate, making it perfect for use with polarising and graduated filters. A deep, petal-shaped hood attaches to the bayonet around the front of the lens. The manual focusing ring is smooth to operate and well damped. Those wishing to manually focus on fast moving subjects may find the amount that the focus ring needs to be moved is a little too much for their tastes, as it has a long travel. As a side effect of this, fine adjustments are a pleasure.

As is the case with Fuji's other X-series optics, this lens has  a manual aperture ring for selecting your desired setting in a more traditional way. The aperture ring is clearly marked and it provides control in third-stop intervals and only requires a light touch to move through the aperture range. This is great for making quick adjustments. Auto focus is quick and precise, with little hunting for focus, even in low light.

The optical stabiliser this lens is equipped with keeps the viewfinder image uncannily steady, which aids accurate autofocus and composition with a telephoto lens. So long as a short pause is given for the image stabiliser to settle, sharp handheld shots are possible around half the time at 1/4sec, which is between five and six stops slower than might be considered safe without the system. A tripod mount is also included, which can be removed via two thumbscrews, which can be a bit fiddly to undo or tighten, if you have fat fingers, like I do.

Fujifilm XF 50-140mm f/2.8 R OIS WR Performance

At 50mm, sharpness already approaches outstanding levels in the centre of the frame at maximum aperture and the clarity achieved towards the edges of the frame is excellent. Stopping down improves performance slightly, with peak performance being achieved between f/4 and f/5.6.

Zooming to 90mm results in outstanding sharpness in the centre of the frame at maximum aperture, although performance towards the edges has fallen away somewhat, with good levels of sharpness just being attained at f/2.8. Stopping down improves performance, especially towards the edges of the frame, reaching a peak at f/8.

Finally, at 140mm, sharpness in the centre of the frame is still outstanding at maximum aperture, and performance towards the edges of the frame is back up to excellent levels. Stopping down has little effect, with the lens performing much the same down to f/8 at this focal length.

How to read our charts

The blue column represents readings from the centre of the picture frame at the various apertures and the green is from the edges. Averaging them out gives the red weighted column.

The scale on the left side is an indication of actual image resolution. The taller the column, the better the lens performance. Simple.

For this review, the lens was tested on a Fujifilm X-T1 using Imatest.

Chromatic aberrations are extremely well controlled for a lens of this type, with fringing barely exceeding a quarter of a pixel width at any zoom setting or aperture. This low level of CA shouldn't cause any issues, even in harsh crops from the edges of the frame, or in large reproductions.

How to read our charts

Chromatic aberration is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software.

Apochromatic lenses have special lens elements (aspheric, extra-low dispersion etc) to minimize the problem, hence they usually cost more.

For this review, the lens was tested on a Fujifilm X-T1 using Imatest.

Falloff of illumination towards the edges of the frame is well controlled for a lens of this type. At 50mm the corners are 1.26 stops darker than the image centre at maximum aperture and at 140mm the corners are 1.59 stops darker. Visually uniform illumination is achieved with the lens stopped down to f/5.6 or beyond throughout the zoom range.

Distortion is reasonably well controlled for a lens of this type. Imatest was able to detect 0.566% pincushion distortion at 50mm and 1.47% pincushion at 140mm. Automatic correction of distortion in camera is very good, and this information can be read by many popular raw image converters, which should mean that distortion is rarely noticeable in practice.

With, or without, the petal-shaped hood attached, this lens is extremely resistant to flare, thanks to a combination of Fujifilm's Super-EBC coatings, combined with a newly developed Nano-GI coating. As a result, it also copes well with shooting into the light retaining good contrast.

Value For Money

This 50-140mm lens from Fuji costs around £1200, which may seem like a lot, but if you compare it to comparable alternatives for other camera systems, it really isn't that expensive at all, especially given how well the lens performs.

There are currently no comparable lenses available for Fuji X-series cameras as currently, Fujifilm have a monopoly on lenses for their own lens mount. 

Fujifilm XF 50-140mm f/2.8 R OIS WR Verdict

Fujifilm's forthcoming range of f/2.8 zoom lenses have been eagerly awaited for some time amongst Fujifilm X-series camera owners, and this first addition to the range does not disappoint.

Although it may seem expensive at first glance, Fujifilm have created a lens capable of delivering image quality of the highest order, that is robustly built, lightweight, weather resistant and that focuses quickly to boot. The performance of this lens puts it on a par with the finest 70-200mm f/2.8 optics available for full frame cameras and invariably, they cost a fair bit more than £1200.

That's a very low price for a Fuji product, here in North America their prices run very high, it's a brand I don't even consider because of that.
