Fujifilm GFX 50S

Posted on Updated on

gfx_50sThe Fujifilm GFX 50S medium-format mirrorless digital camera will launch late February with an initial selection of three Fujinon lenses – the GF 63 mm f/2.8 R WR, the GF 32-64 mm f/4 R LM WR, and the GF 120 mm f/4 R LM OIS WR Macro. Three more lenses will be arriving later in the year.

The GFX system utilizes a 43.8 x 32.9 mm, 51.4-megapixel CMOS sensor. The sensor has approximately 1.7x the area of a what we have come to call full-format of full size (i.e 35 mm) sensor.

Compared to a full size sensor with equivalent megapixels, the company explains, both resolution and sensitivity are dramatically better due to the larger size of each pixel. As a result, the sensor captures great textures and subtlety of tone, unique to large size sensors. The texture and tone combine to give a unique three-dimensional effect.

For flash photography in the studio or outdoors during the day, the sensor has a native ISO of 100. The sensor can also be adapted to various aspect ratios, including 4:3, 3:2, 16:9, 1:1, 65:24, 5:4, 7:6.

The GFX 50S uses the X Processor Pro (also used in the X-Pro2 and X-T2 cameras) and allows photographers to use proprietary Film Simulations with a medium-format sensor. The camera supports Full HD recording at 29.97p/25p/24p/23.98p. Fuji says users can enjoy high quality video with no post-processing required by using Film Simulation modes just like they would with a still image. The GFX 50S introduces a new Color Chrome Effect feature that reproduces subtle tones in highly saturated subjects.

With a compact and lightweight body constructed from magnesium alloy, the camera weighs approximately 43 ounces when paired with the 63 mm lens, and weighs approximately 60 percent that of a medium-format DSLR camera equipped with a sensor of the same size. When compared to a full-frame camera, the weight is almost identical.

Fuji suggests overall camera body height and width have also been minimized for maximum flexibility, overturning the common perceptions regarding the mobility of medium-format digital cameras.

gfx_50s-backThe GFX 50S has a 3.69-million dot organic EL electronic viewfinder and 2.36-million dot touchscreen LCD back panel. The EVF is detachable to allow for flexible operation. Users can attach the accessory EVF-TL1 EVF tilt adapter (sold separately) to allow the finder to be tilted to 90° vertically and swung ±45°. A 3.2-inch touch panel is used for the rear monitor, with touch operation for the menu, focusing points and image playback.

As part of the GFX system, Fujifilm is launching newly developed, ultra-high resolution Fujinon GF lenses. Taking advantage of the mirrorless system’s structure, the G Mount has a short flange back distance of just 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 more than 100-megapixels.

GFX lens barrels feature an aperture ring in the same manner as XF lenses. A new C (Command) Position has been added to the aperture ring, allowing users to change the aperture with the camera’s command dial. The A (Auto) Position and C Position feature a locking button installed on the aperture ring that must be disabled to implement changes.

Just as with flagship X Series models, the GFX 50S features dedicated dials to independently set aperture, shutter speed, and ISO.

Aperture and ISO feature a C (Command) and the shutter speed dial has a T (Time) Position. Setting the dial to this position allows the user to change exposure settings using the command dials on the front and rear of the camera body. The user can choose between these two operation methods according to their preference, ease of use, and the shooting environment.

The GFX 50S is equipped with a 1.28-inch LCD sub monitor on the top of the body. Exposure data such as aperture and shutter speed is displayed on this screen.

A 117-point (9 x 13 / maximum of 425 points when miniaturized) contrast AF system is used. High-precision AF on the imaging sensor dramatically improves focusing accuracy with the shallow depth of field produced by medium-format lenses. First adopted in the X-Pro2, focus point selection can be performed by using the Focus Lever, which allows intuitive movement of the focus point. Alternatively, users can select the focus point from the touch panel LCD screen.

The camera is weather and dust resistant, operating to as low as 14 F \ -10 C.

File formats include three different JPEG settings as well as two different RAW settings (uncompressed, compressed). TIFF output is also possible with in-camera RAW development.

The camera has two SD card slots (UHS-II recommended), and supports three different types of recording methods: “Sequential,” in which recording can be continued according to shooting order, “Backup,” which records the same data on two cards simultaneously, and “Sorting,” which records RAW and JPEG data on separate cards.

A newly-developed high capacity battery is said to deliver approximately 400 photos (with Auto Power Save ON).

The Fujinon GF 63 mm f/2.8 R WR (equivalent to 50 mm in 35 mm format) has an optical system featuring a construction of 8 groups and 10 elements, including one ED lens element. The external form of this lens has a diameter of 84.0 x 71.0 mm with a weight of 14.2 ounces \ 405 g. Using the front group for the focus, aberrations due to focus distance are suppressed, achieving high resolution performance even when wide open from the center to the edges of the lens, says the company.

gfx_50s-topThe Fujinon GF 32-64 mm f/4 R LM WR (equivalent to 25-51 mm) features a construction of 11 groups and 14 elements, 3 aspheric elements, one ED lens and one super ED lens. The lens demonstrates extremely high performance from the center all the way to the edges, uses internal focusing, reducing the weight of the focus lens and achieving fast and silent AF by driving focus using a linear motor, notes the company.

The Fujinon GF 120 mm f/4 R LM OIS WR Macro (equivalent to 95 mm) has a construction of 9 groups and 14 elements, including 3 ED lens elements. By adopting a floating focus method using a linear motor, silent high-speed autofocusing is achieved while aberrations are corrected, dramatically increasing the resolution, Fuji says. Furthermore, by arranging the ED lenses properly, chromatic aberrations are also properly corrected. This lens is equipped with optical image stabilization (OIS) effective up to 5.0-stops.

The three additional GF lenses on their way: GF 110 mm f/2 R LM WR (equivalent to 87 mm), GF 23 mm f/4 R LM WR (equivalent to 18 mm), and GF 45 mm f/2.8 R WR (equivalent to 35 mm).

All GF lenses are dust and weather resistant, built to withstand operation at temperatures as low as 14 F \ -10 C, and have a Fluorine coating applied to the front lens element to create a hydrophobic coating that repels moisture.

A number of accessories will be sold separately, including a vertical battery grip; EVF Tilt Adapter; H Mount Adapter G (allowing you to use Super EBC Fujinon HC lenses developed for the GX645AF); View Camera Adapter G, allowing the GFX 50S to be used as a digital back; and tethered shooting solutions.

The Fujifilm GFX 50S camera body will be available late February for $8,499.99. Also available in February will be the first three GF lenses: GF 63 mm at $1,899.99, GF 32-64 mm for $2,999.99, and GF 120 mm for $3,499.99.
