Introduction

The Fujifilm GF 45mm F2.8 R WR is a new wide-angle prime lens designed specifically for the G-mount Fujifilm GFX 50S mirrorless camera. This lens features a focal range of 36mm in 35mm terms making it ideal for street, documentary and everyday photography, an aperture range of f/2.8-f/32, 11 elements in 8 groups including 1 aspherical and 2 ED elements, 9 rounded aperture blades, a linear AF motor, Nano GI coating to help reduce ghosting and flare, and a dust-, freeze- and weather-sealed physical construction. The Fujifilm GF 45mm F2.8 R WR retails for around $1699 / £1579.

Ease of Use

With a maximum diameter of 84mm and a length of 88mm, the Fujifilm GF 45mm F2.8 R WR is a moderately wide-angle prime lens that's very well-suited to the GFX 50S camera that we tested it with. Weighing in at 490g, it's quite a lightweight lens, feeling very well-balanced on the GFX 50S.

As with the other GF lenses that we've reviewed previously, the Fujifilm GF 45mm F2.8 R WR boasts excellent build quality. The lens is dust, freeze and moisture resistant and it features a metal bayonet. It accepts 62mm filters via metal threads. There is no built-in optical image stabilisation in this lens.

The focus ring is generously 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. It 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 GF 45mm f4 R LM 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 too, taking about 0.25 second to lock onto the subject in good light. We didn't experience too much "hunting" either, with the lens accurately focusing almost all of the time.

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 45mm 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 C (Command) position which allows you to set the aperture via the camera body rather than the lens.

Focal Range

The 45mm focal length gives an angle of view of 62.6 degrees on a 35mm full frame sensor, which is equivalent to a focal length of 36mm.

Chromatic Aberrations

Chromatic aberration (purple fringing) is a non-issue with the Fujifilm GF 45mm F2.8 R WR lens, only appearing in very high contrast situations.

Light Fall-off and Distortion

Light fall-off is noticeable wide open at f/2.8, though this can easily be corrected in Photoshop. Stop down to f/5.6 and the vignetting is already much less prominent, but it is still visible when shooting pale scenes that fill the frame.

Macro

A minimum focus distance of 45cm and a maximum magnification ratio of 0.14x doesn't make the lens very useful for shooting close subjects. This image is uncropped and shows how close you can get to a Compact Flash card.

Bokeh

The Fujifilm GF 45mm F2.8 R WR 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 images showing all the available apertures to see the Fujifilm GF 45mm F2.8 R WR’s bokeh quality for yourself.
