Fujifilm has announced two new Fujinon GF lenses for its GFX 50S medium-format mirrorless digital camera system, the GF110 mm f/2 R LM WR (equivalent to 87 mm) and the GF23 mm f/4 R LM WR (equivalent to 18 mm).
The company notes the G Mount has a short flange back distance of 26.7 mm that reduces the back focus distance as much as possible. This prevents vignetting and achieves edge-to-edge sharpness. All GF lenses have been designed to support sensors of over 100-megapixels.
The company says the 110 mm lens is perfect for portraits, while the 23 mm lens is suited for landscape and architectural photography. Fujifilm states that, despite the super-wide angle of view of the latter lens, distortion is kept to a minimum.
Both new lenses feature fast and quiet autofocus by using a linear motor, are dust and weather resistant, and are capable of operating in environments as cold as 14°F / -10°C.
The 110 mm lens has 14 elements in 9 groups, including 4 ED lens elements: Super ED lens and three ED lenses for suppressed chromatic aberration and high resolution performance all the way to the edges, with a 9 blade aperture. The 23 mm lens has12 groups and 15 elements construction using two aspherical lenses, one super ED lens, and three ED lenses, and uses a 9 blade aperture, plus Nano GI coating to suppress ghosting and flare.
The GF110 mm f/2 R LM WR will be available in late June for $3,599.99 and the GF23 mm f/4 R LM WR will also be available in late June for $3,399.99.
It has a similar size and design to the existing XF35 mm f/2.
The inner-focus AF system uses a stepping motor to drive lightweight focusing elements for silent and fast autofocus, says the company. When combined with the phase detection AF system of the X-Pro2 and X-T2, the lens can focus in 0.05 seconds.
The exterior is metal, and Fujifilm notes the aperture ring and focus ring have been designed with just the right amount of clicking and torque for optimum feedback and operability.
The lens is weather and dust resistant and operates at temperatures as low as -10°C / 14°F.
The lens features 10 elements in 6 groups with 2 aspherical elements; Super EBC (Super Electron Beam Coating) reducing both flare and ghosting; minimum working distance of less than 9 inches.
The Fujinon XF23 mm f/2 R WR will be available in September, initially in black only.
The lens has a focal length equivalent of a 35 mm lens and features a camera-to-subject distance indicator and a depth-of-field scale on the barrel.
Lens distortion is claimed to have been reduced to an absolute minimum using only optical rather than digital correction. The rounded seven-blade diaphragm ensures smooth bokeh.
The 23 mm lens uses an internal focusing system which incorporates a lens group consisting of three cemented lens elements and one aspheric lens element. Additionally, the built-in high-torque DC coreless motor delivers ultra-fast AF performance, says the company.
All lens elements are treated with Fujifilm’s multilayer HT-EBC (High Transmittance Electron Beam Coating) which delivers enhanced durability and ensures an even spread of light across the sensor.
The lens weighs 300.5 g (10.6oz) and measures 7.2 cm (2.84 inches) in length making it the most compact and lightweight lens in its class, says Fuji. Metal parts are used for the focus and aperture rings, which are designed to give just the right amount of torque and feel.
The Fujinon XF23 mm f/1.4 R will be available in October for $899.95.
