Manufacturer description

Valhalla, N.Y., January 19, 2017 – As the leader in innovation for photographers, FUJIFILM North America Corporation today announces the FUJIFILM GFX 50S medium format mirrorless digital camera that will launch late February, 2017 with an initial selection of three FUJINON lenses - the GF63mmF2.8 R WR, the GF32-64mmF4 R LM WR, and the GF120mmF4 R LM OIS WR Macro. These lenses encapsulate the design philosophy of FUJINON lenses that are renowned by photographers around the world.

The innovative GFX system utilizes a Fujifilm exclusive 43.8 x 32.9mm (FUJIFILM G Format) 51.4MP CMOS sensor. The GFX 50S combines the heritage of over 80 years of imaging and the innovative award-winning functional design of our X Series digital camera system in the relentless pursuit of image quality.

The FUJIFILM GFX 50S Revealed

The FUJIFILM GFX 50S mirrorless digital camera uses the new 51.4MP FUJIFILM G Format 43.8 x 32.9mm sensor with approximately 1.7x the area of a 35mm sensor. In addition to the camera are three new FUJINON GF Lenses that will be followed by three additional lenses later in 2017.

The GFX 50S 51.4MP sensor shows its true potential when making large format prints, capturing majestic landscape photos or reproducing historical documents. Compared to a full size sensor with equivalent megapixels, 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 that is unique to large size sensors. The texture and tone combine to give a unique three-dimensional effect creating extremely high quality photography. Images captured can be reproduced down to the smallest detail, conveying the texture of the subject, a three-dimensional feeling, and the atmosphere of the scene.

For flash photography in the studio or outdoors during the day, the GFX 50S 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, all of which are available in large and medium format film cameras.

The FUJIFILM GFX 50S uses the X Processor Pro (also used in the X-Pro2 and X-T2 cameras) and allows photographers to use Fujifilm's proprietary Film Simulations with a Medium Format sensor. The camera supports Full HD recording at 29.97p/25p/24p/23.98p. 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.

Ultimate Performance in a Compact Body

With a compact and lightweight body constructed from magnesium alloy, the FUJIFILM GFX 50S weighs approximately 43 ounces when paired with the FUJINON GF63mmF2.8 R WR, and weighs approximately 60% of a medium format DSLR camera equipped with a sensor of the same size. When compared to a full frame, the weight is almost identical. 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.

Bright, Crystal Clear Viewfinder and Large Touchscreen

The FUJIFILM GFX 50S gives users a 3.69M dot organic EL electronic viewfinder and 2.36M dot touchscreen LCD back panel for easy viewing. 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, 2.36M dot touch panel is used for the rear monitor, with touch operation for the menu, focusing points and image playback. A three-directional tilting LCD screen improves operability and makes viewing images and checking focus even easier.

FUJINON Lenses Guarantee Image Perfection

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 26.7mm that reduces the back focus distance as much as possible. This prevents vignetting and achieves edge-to-edge sharpness. All FUJINON GF Lenses have been designed to support sensors of over 100MP.

GFX lens barrels feature an aperture ring in the same manner as FUJINON XF lenses, for intuitive operation. 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.

Built for the Professional, and the Enthusiast

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

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. Important exposure data such as aperture and shutter speed is displayed on this screen. This display is extremely useful when shooting on a tripod or tethered to a computer.

A 117-point (9 x 13 / maximum of 425 points when miniaturized) contrast AF system is used on the GFX 50S. 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 FUJIFILM 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.

Initial Lens Lineup Will Include the Following Three FUJINON Options:

  • GF63mmF2.8 R WR (equivalent to 50mm in 35mm format)
  • GF32-64mmF4 R LM WR (equivalent to 25-51mm in 35mm format)
  • GF120mmF4 Macro R LM OIS WR (equivalent to 95mm in 35mm format)

GFX 50S Accessories (sold separately)

Vertical Battery Grip VG-GFX1 – high-performance battery grip is designed to place the release button, dials, and function buttons in the same positions when shooting vertically. The battery grip can be loaded with one NP-T125 dedicated battery, lowering the frequency that batteries need replacing. Also, by connecting the AC-15V accessory (sold separately), it is possible to charge the battery within the grip in approximately 2 hours.

EVF Tilt Adapter EVF-TL1 – mounting this accessory between the camera body and EVF, the angle of the EVF can be changed to angles from 0°〜90° vertically and from -45°〜+45° horizontally. Doing this allows the user to shoot at various angles while using the viewfinder, greatly increasing the versatility of the finder for different subjects.

H Mount Adapter G – allows you to use SUPER EBC FUJINON HC interchangeable lenses developed for the FUJIFILM GX645AF medium format film camera (discontinued). By attaching this adapter to the GFX 50S, a total of 9 SUPER EBC FUJINON HC interchangeable lenses and 1 tele-converter developed for the GX645AF can be used. While the focusing method will be limited to manual focusing, the lens aperture can be changed using the command dial on the camera body, and shooting with the leaf shutter built in to the lenses is also possible. Using this lens shutter will allow high speed flash synchronization up to a maximum speed of 1/800 sec.

Also, the adapter is equipped with electrical contacts that can communicate with the camera body, independently creating, saving, and applying correctional data for each lens. The adapter supports Manual and Aperture Priority AE exposure modes.

*A removable tripod foot is included to mount the camera with a heavy or long focal length lens.

View Camera Adapter G – allows the GFX 50S to be used as a digital back. The view camera adapter allows the GFX 50S to be mounted to the standard universal-type back of a view camera. This allows the use of FUJINON large format camera lenses, such as the CM-W FUJINON lens series. The camera or lens shutter can be triggered, allowing the user to choose the optimum method. The large image circle and the bellows of the view camera can be used with tilt, shift and swing movements, effective for product and architectural photography.

*There may be instances in which the adapter cannot be mounted depending on the shape of the view camera.

Tethered Shooting Solutions – We have the following tethering solutions for photographers, including: X Acquire to transfer images from the camera to a hot folder on your computer for use with your preferred imaging software, Tether Shooting Plug-in PRO for Adobe® Photoshop® Lightroom® and HS-V5 for Windows (sold separately).

By connecting the GFX 50S to a PC via USB cable and using this software, it is possible to transfer photographed images directly to the PC, as well as control the camera from the PC. Also, by using the Control Panel Window newly added to Tether Shooting Plug-in PRO for Adobe® Photoshop® Lightroom®, additional camera functions become available.

RAW FILE CONVERTER EX2.0 – powered by SILKYPIX (free of charge) RAW development software and Adobe® Photoshop® Lightroom® / Adobe® Photoshop® CC (sold separately). RAW development software is used for detailed corrections and advanced image processing that isn't supported by the in-camera RAW conversion. Both software support Fujifilm's "Film Simulation" modes, allowing creation of image data that is extremely close to Fujifilm’s advanced color reproduction.

Cannot perform comparison

Cannot compare the lens to itself.

Image stabilizer

A technology used for reducing or even eliminating the effects of camera shake. Gyro sensors inside the lens detect camera shake and pass the data to a microcomputer. Then an image stabilization group of elements controlled by the microcomputer moves inside the lens and compensates camera shake in order to keep the image static on the imaging sensor or film.

The technology allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without image stabilizer you have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.

Original name

Lens name as indicated on the lens barrel (usually on the front ring). With lenses from film era, may vary slightly from batch to batch.

Format

Format refers to the shape and size of film or image sensor.

35mm is the common name of the 36x24mm film format or image sensor format. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43mm. The name originates with the total width of the 135 film which was the primary medium of the format prior to the invention of the full frame digital SLR. Historically the 35mm format was sometimes called small format to distinguish it from the medium and large formats.

APS-C is an image sensor format approximately equivalent in size to the film negatives of 25.1x16.7mm with an aspect ratio of 3:2.

Medium format is a film format or image sensor format larger than 36x24mm (35mm) but smaller than 4x5in (large format).

Angle of view

Angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view.

As the focal length changes, the angle of view also changes. The shorter the focal length (eg 18mm), the wider the angle of view. Conversely, the longer the focal length (eg 55mm), the smaller the angle of view.

A camera's angle of view depends not only on the lens, but also on the sensor. Imaging sensors are sometimes smaller than 35mm film frame, and this causes the lens to have a narrower angle of view than with 35mm film, by a certain factor for each sensor (called the crop factor).

This website does not use the angles of view provided by lens manufacturers, but calculates them automatically by the following formula: 114.6 * arctan (21.622 / CF * FL),

where:

CF – crop-factor of a sensor,
FL – focal length of a lens.

Mount

A lens mount is an interface — mechanical and often also electrical — between a camera body and a lens.

A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock type. Modern camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body, unlike screw-threaded mounts.

Lens mounts of competing manufacturers (Canon, Nikon, Pentax, Sony etc.) are always incompatible. In addition to the mechanical and electrical interface variations, the flange focal distance can also be different.

The flange focal distance (FFD) is the distance from the mechanical rear end surface of the lens mount to the focal plane.

Lens construction

Lens construction – a specific arrangement of elements and groups that make up the optical design, including type and size of elements, type of used materials etc.

Element - an individual piece of glass which makes up one component of a photographic lens. Photographic lenses are nearly always built up of multiple such elements.

Group – a cemented together pieces of glass which form a single unit or an individual piece of glass. The advantage is that there is no glass-air surfaces between cemented together pieces of glass, which reduces reflections.

Focal length

The focal length is the factor that determines the size of the image reproduced on the focal plane, picture angle which covers the area of the subject to be photographed, depth of field, etc.

Speed

The largest opening or stop at which a lens can be used is referred to as the speed of the lens. The larger the maximum aperture is, the faster the lens is considered to be. Lenses that offer a large maximum aperture are commonly referred to as fast lenses, and lenses with smaller maximum aperture are regarded as slow.

In low-light situations, having a wider maximum aperture means that you can shoot at a faster shutter speed or work at a lower ISO, or both.

Closest focusing distance

The minimum distance from the focal plane (film or sensor) to the subject where the lens is still able to focus.

Closest working distance

The distance from the front edge of the lens to the subject at the maximum magnification.

Magnification ratio

Determines how large the subject will appear in the final image. For example, a magnification ratio of 1:1 means that the image of the subject formed on the film or sensor will be the same size as the subject in real life. For this reason, a 1:1 ratio is often called "life-size".

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Electronic manual focus override is performed in the following way: half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the focusing ring.

Manual diaphragm

The diaphragm must be stopped down manually by rotating the detent aperture ring.

Preset diaphragm

The lens has two rings, one is for pre-setting, while the other is for normal diaphragm adjustment. The first ring must be set at the desired aperture, the second ring then should be fully opened for focusing, and turned back for stop down to the pre-set value.

Semi-automatic diaphragm

The lens features spring mechanism in the diaphragm, triggered by the shutter release, which stops down the diaphragm to the pre-set value. The spring needs to be reset manually after each exposure to re-open diaphragm to its maximum value.

Automatic diaphragm

The camera automatically closes the diaphragm down during the shutter operation. On completion of the exposure, the diaphragm re-opens to its maximum value.

Fixed diaphragm

The aperture setting is fixed at F/ on this lens, and cannot be adjusted.

Number of blades

As a general rule, the more blades that are used to create the aperture opening in the lens, the rounder the out-of-focus highlights will be.

Some lenses are designed with curved diaphragm blades, so the roundness of the aperture comes not from the number of blades, but from their shape. However, the fewer blades the diaphragm has, the more difficult it is to form a circle, regardless of rounded edges.

At maximum aperture, the opening will be circular regardless of the number of blades.

Weight

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

Maximum diameter x Length

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

For lenses with collapsible design, the length is indicated for the working (retracted) state.

Weather sealing

A rubber material which is inserted in between each externally exposed part (manual focus and zoom rings, buttons, switch panels etc.) to ensure it is properly sealed against dust and moisture.

Lenses that accept front mounted filters typically do not have gaskets behind the filter mount. It is recommended to use a filter for complete weather resistance when desired.

Fluorine coating

Helps keep lenses clean by reducing the possibility of dust and dirt adhering to the lens and by facilitating cleaning should the need arise. Applied to the outer surface of the front and/or rear lens elements over multi-coatings.

Filters

Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images.

Lens hood

A lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background.

The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood.

Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens.

Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself.

Teleconverters

Teleconverters increase the effective focal length of lenses. They also usually maintain the closest focusing distance of lenses, thus increasing the magnification significantly. A lens combined with a teleconverter is normally smaller, lighter and cheaper than a "direct" telephoto lens of the same focal length and speed.

Teleconverters are a convenient way of enhancing telephoto capability, but it comes at a cost − reduced maximum aperture. Also, since teleconverters magnify every detail in the image, they logically also magnify residual aberrations of the lens.

Lens caps

Scratched lens surfaces can spoil the definition and contrast of even the finest lenses. Lens covers are the best and most inexpensive protection available against dust, moisture and abrasion. Safeguard lens elements - both front and rear - whenever the lens is not in use.
