Fujifilm launches FUJINON Lens GF55mmF1.7 R WR

TOKYO, September 12, 2023 – FUJIFILM Corporation (President & CEO, Representative Director: Teiichi Goto) announces the release of the “FUJINON Lens GF55mmF1.7 R WR” (GF55mmF1.7 R WR) in late September, 2023. The new lens joins the lineup of GF lenses, i.e. interchangeable lenses for the GFX Series of Fujifilm’s mirrorless digital cameras equipped with the large-format sensor^*1 measuring approximately 1.7 times that of the 35mm full-frame sensor.

The GF55mmF1.7 R WR is a large-diameter prime lens with the standard focal length of 55mm (equivalent to 44mm in the 35mm film format). The large-format’s enriched descriptive capability is combined with the creamy bokeh characteristic of the large maximum aperture makes the main subject stand out against a blurred background. The lens’s focal length is the same as the diagonal measurement of GFX Series’ signature large-format sensor and gives the field of view close to that of human vision to create a natural perspective. It sets a new standard in GF lenses, which brings out the best of large-format cameras.

GF55mmF1.7 R WR features the maximum aperture of F1.7, consisting of 14 lens elements in 10 groups including two ED lenses and two aspherical lenses. The lens features optimally-positioned aspherical elements and uses the eight-element focusing lens group including one of the aspherical lenses and two ED lenses. This effectively controls shifts in chromatic aberration, spherical aberration and comatic aberration when the focusing position changes, thereby delivering a soft creamy bokeh and advanced image-resolving performance, characteristics of large-aperture lenses. The lens has a normal focal length, making it highly versatile in all shooting situations. Users can enjoy the full appeal of the large-format sensor in genres ranging from day-to-day snapshots to full-fledged portraiture both indoors and outdoors.

• *1 An image sensor that measures 55mm diagonally (43.8mm x 32.9mm) and is approximately 1.7 times larger than a 35mm full-frame sensor

• The lens consists of 14 lens elements in 10 groups including two ED lenses and two aspherical lenses, creating soft and beautiful bokeh characteristic of large-aperture lenses.
• An aspherical lens, produced at ultra-high precision, is placed behind aperture blades to optimally control spherical aberration for soft back blur. The other aspherical lens is placed at the back to deliver edge-to-edge sharpness.
• The focusing lens group generously features eight lens elements including one aspherical lens and two ED lenses to achieve advanced image-resolving performance across the entire focusing range for bokeh with beautifully-softened edges.
• High refractive lenses that suppress aberration fluctuation, typically used in cinema camera lenses, are used as the front element and also in the focusing group. This controls spherical aberration and helps deliver advanced image-resolving performance regardless of focusing positions.
• This is the first GF lens to use 11 diaphragm blades to achieve a near-perfect circle in the aperture. This is why the lens can produce rounded bokeh even when the lens is stopped down slightly from being wide open, creating beautiful bokeh in a wide variety of photographic scenes.

• The lens has a normal focal length of 55mm (equivalent to 44mm in the 35mm film format), making it highly versatile in all shooting situations. Users can take advantage of the maximum aperture of F1.7 to enjoy portraiture that makes the main subject stand out, casual snapshots of everyday scenes and street photography that captures how the main subject relates to the background.

• The GF55mmF1.7 R WR uses a DC motor that precisely controls 14 lens elements in 10 groups. The motor allows the lens to autofocus on the subject quickly and accurately, even when shooting that requires advanced focusing skills, to ensure users capture decisive photo opportunities.

• The lens barrel is weather-sealed in nine places to ensure dust and weather resistance, and the ability to operate at temperatures as low as -10℃. This means users can enjoy the lens with peace of mind to take photos outdoors in light rain or in dusty outdoor places.
• The use of ultra-high-precision aspherical lenses and optimized lens design mean this lens only weighs 780g and measures 99.3mm in length despite being a larger-diameter lens with the maximum aperture of F1.7. This reduces users’ strains in walking around with the lens mounted on a camera, adding an extra sense of mobility as a standard walkaround lens.
