Ease of Use

With a maximum diameter of 90mm and a length of 152mm, the Fujifilm GF 120mm f4 R LM OIS WR Macro is a short telephoto fixed focal length optic that’s fairly well-suited to the GFX 50S camera that we tested it with. Weighing in at 980g, it’s quite a heavy lens, but proved to be quite well-balanced on the equally new GFX 50S.

The Fujifilm GF 120mm f4 R LM OIS WR Macro boasts excellent build quality. The lens is dust and moisture resistant and it features a metal bayonet.

The focus ring is very wide, smooth and beautifully well-damped in action without being loose, and has a ridged, rubberised grip band. There are no “hard stops” at either end of the 45cm-infinity focus range though.

Focusing is usefully internal and manual focusing is possible when set via the camera body. Full-time manual focus override is not available at any time simply by rotating the focus ring.

The Fujifilm GF 120mm f4 R LM OIS WR Macro has a focus limiter switch with three settings – Full, 09m-infinity and 0.45-0.9m.

The Fujifilm GF 63mm f2.8 R WR lens has a traditional aperture ring on the lens barrel, which allows you to set the aperture in 1/3 steps, complete with full aperture markings. The aperture is also shown in the viewfinder or on the LCD screen. The aperture ring is nicely damped and makes a distinctive click as you change the setting. The aperture ring toggles between auto aperture control (the ring is set to A) or manual aperture control (the switch is set to one of the aperture values) or the new C (Command) position which allows you to set the aperture via the camera body rather than the lens.

The Fujifilm GF 120mm f4 R LM OIS WR Macro lens is comprised of 14 elements in 9 groups including 3 extra-low dispersion elements. It accepts 72mm filters via metal threads.

There is built-in optical image stabilisation in this lens which is equivalent to 5-stops, turned on and off by the dedicated OIS switch on the side of the lens barrel.

Focal Range

The 90mm focal length gives an angle of view of 25.7 degrees on a 35mm full frame sensor, which is equivalent to a focal length of 95mm.

Focusing

The Fujifilm GF 63mm f2.8 R WR’s manual focussing ring spans a significant width of the lens barrel and is exceptionally smooth to operate. It also has a large rotation angle which enables precise focusing and moves smoothly without any play. Two different focusing aids are provided – auto magnification and focus peaking. In conjunction with the GFX 50S’ high-resolution electronic viewfinder, we found it very easy to accurately determine critical sharpness.

When it comes to auto-focusing, the Fujifilm GF 63mm f2.8 R WR is a very quiet performer on the Fujifilm GFX 50S that we tested it with thanks to the linear motor, and it’s also pretty fast for a macro lens, taking about 0.5 second to lock onto the subject in good light. We didn’t experience too much “hunting” with good lighting, with the lens accurately focusing almost all of the time, but it was prone to hunting in more dim environments.

Chromatic Aberrations

Chromatic aberration (purple fringing) is a non-issue with the Fujifilm GF 120mm f4 R LM OIS WR Macro lens, only appearing in very high contrast situations.

Light Fall-off and Distortion

Light fall-off is noticeable wide open at f/4, though this is to be expected for such a fast lens and can easily be corrected in Photoshop. Stop down to f/8 and the vignetting is already less prominent, but it is still visible when shooting pale scenes that fill the frame.

Macro

A 45cm minimum focus distance makes the lens very useful for shooting close subjects, as does the maximum magnification ratio of 0.5x. This image is uncropped and shows how close you can get to a Compact Flash card.

Close-up performance

Bokeh

A major appeal of fast, wide-aperture prime lenses is their ability to produce an eye-catching separation between a sharp subject and a very soft out-of-focus background. The Fujifilm GF 120mm f4 R LM OIS WR Macro generates smooth out of focus areas thanks to having 9 rounded aperture blades. Bokeh is however a fairly subjective part of a lens’ image quality, so check out these 100% crops to see the Fujifilm GF 120mm f4 R LM OIS WR Macro’s bokeh quality for yourself.

Sharpness

In order to show you how sharp this lens is, we are providing 100% crops on the following page.

Sharpness at 120mm

Our sharpness tests were conducted using a 50-megapixel Fujifilm GFX 50S body mounted on a tripod. The camera’s shutter release was also set on a timer-delay to avoid any possible camera shake. The test subject was shot using ambient lighting, hence some colour and contrast variation is to be expected between apertures.

Centre sharpness is impressively high throughout the entire aperture range, with peak performance between f/5.6-f/22. Corner sharpness is also excellent, again producing optimal sharpness at f/5.6-f/22.

Conclusion

The Fujifilm GF 120mm f4 R LM OIS WR Macro is very versatile, doubling up as both a macro and portrait lens thanks to its 1:2 magnification, 45cm close focus distance, speedy auto-focusing (for such a large lens) and very effective optical image stabilisation. It might not be the fastest optic on the block, but the outstanding image quality and intuitive handling makes up for that. On the downside, it is undoubtedly a heavy and expensive lens.

The GF 120mm is a very sharp lens that exhibits almost no chromatic aberrations, has negligible distortion and is capable of producing some lovely bokeh. Vignetting at wide-open apertures is the only real optical issue of note, although stopping down to f/8 solves the problem altogether.

The high-speed linear AF motor makes it suitable for life in the studio (or out) as a portrait lens, and it obviously does very well as a dedicated macro lens. As with Fujifilm’s X-series lenses, build quality is excellent, with the metal lens mount and sober all-black design adding to the high-quality feel, and the continuation of the traditional aperture ring being very welcome. Manual focusing is also a pleasure thanks to the massive, well-damped focusing ring.

Although it’s the most expensive of the three lenses that Fujifilm chose to launch alongside the GFX 50S camera, the fact that the Fujifilm GF 120mm f4 R LM OIS WR Macro can very effectively double up for both macro and portraiture makes it more of a sound investment than a first glance at the spec sheet might suggest.
