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 features 9 elements in 7 groups, including one aspherical ED lens, and has an inner focusing system, driven by a stepping motor for fast and silent autofocusing. The lens is also weather and dust resistant, and operates in temperatures as low as 14°F\-10°C.
Aperture and focusing rings feature precise click stops and smooth damping for easy operation. Super EBC (Super Electron Beam Coating) ensures high performance by reducing both flare and ghosting
The Fujifilm XF 50 mm f/2 R WR (black and silver) will be available in February for $649.99.
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 Fujinon XF 100-400 mm f/4.5-5.6 R LM OIS WR is a weather-sealed telephoto lens with a 152-609 mm equivalent in 35 mm format. The lens has an optical construction of 21 elements in 14 groups, and includes five ED lenses and one Super ED lens to help reduce chromatic aberration. Fujifilm says it delivers the highest image quality in its class.
The lens has been designed for handheld shooting with a 5.0-stop image stabilization system and twin linear motors for speedy autofocus. This, says the company, makes it perfect for shooting fast-moving subjects.
The lens is also water and dust resistant and can operate in temperatures as low as -10°C. A fluorine coating has also been applied to the front lens element to repel water and dirt.
The lens includes a hood features a sliding window for accessing a polarizing filter and locking mechanism.
The lens is compatible with the XF1.4X TC WR teleconverter and optional lens plate MLP-75XF.
The Fujinon XF 100-400 mm f/4.5-5.6 R LM OIS WR lens will be available in February for $2,149.99.
The new compact Fujinon XF90 mm f/2 R LM WR lens is a weather-resistant, fast-aperture prime lens. It’s the equivalent of 137 mm and uses an optical construction of 11 elements in 8 groups (including three ED glass elements to reduce lateral and axial chromatic aberration). Nano-GI coating alters the refractive index between glass and air to reduce ghosting and flare.
Weight is less than 20 ounces, with a minimum working distance of approximately 24 inches.
The lens uses a newly-developed Quad Linear Motor that is said to deliver fast, accurate autofocus as fast as 0.14 seconds. The new linear motor is fast, quiet and accurate, and uses four magnets for higher torque and a high-speed autofocus.
The lens is weather and dust-resistant and can work in temperatures down to 14°F.
The Fujinon XF90 mm f/2 R LM WR will be available in July for C$1,099.99.
