GFX 50S II
A Smaller Entry into the GFX Medium Format System
The Fujifilm GFX 50S II, released on 29 September 2021, is the more compact and accessible member of the GFX family, sharing sensor lineage with its predecessor while adding meaningful updates including in-body image stabilisation. It sits below the flagship GFX 100 II in Fujifilm's lineup, trading that camera's approximately 102 MP sensor and professional video specs for a lighter, more field-friendly body. Within the G-Mount ecosystem, the GFX 50S II is the entry point for photographers who want medium format resolution without the bulk or expense of the 100-series bodies.
51.4 MP on a 43.8 x 32.9 mm Sensor: What the Numbers Actually Mean
The 43.8 mm x 32.9 mm CMOS sensor delivers 51.4 MP at 8256 x 6192 pixels and covers approximately 1.7 times the area of a 35 mm full-frame sensor. That extra surface area captures more light per pixel at equivalent f-stops, producing a tonal depth and microcontrast that reviewers consistently note as distinct from even high-resolution full-frame bodies. For print and commercial work, files hold up to very large enlargements, and the native 4:3 aspect ratio suits portrait orientation without cropping waste.
ISO Range and Exposure Headroom
The standard ISO range runs from 100 to 12800, extending further to ISO 50 at the low end and ISO 102400 at the top in expanded mode. Reviewers note the large pixel pitch of the medium format sensor keeps noise well managed at mid-range sensitivities, and the usable ceiling for editorial and commercial work sits comfortably within the native range. The mechanical shutter spans 4 seconds to 1/4000 s, while the electronic shutter extends to 1/6000 s for situations that benefit from silent operation or faster ceiling speeds.
In-Body Stabilisation on a Medium Format Body
The GFX 50S II gained a five-axis in-body image stabilisation system, which Fujifilm rates at up to 6.5 stops of compensation when paired with compatible G-Mount lenses. This is a significant development for a medium format camera, where longer effective focal lengths and larger physical lenses can otherwise demand a tripod for handheld work. Consensus indicates this stabilisation makes the GFX 50S II meaningfully more usable in available light, natural light portraiture, and travel contexts where a tripod is impractical.
Autofocus Architecture and Burst Rate
The AF system relies on TTL contrast-detection across 117 focus points, with modes covering single point, zone, and wide/tracking selection. Contrast-detect autofocus works well in methodical, deliberate shooting, but users report it is noticeably slower than the phase-detect systems in the GFX 100 II or Fujifilm's own X-H2S. The continuous burst rate of 3 fps reflects the camera's design intent: the GFX 50S II is a considered, slow-paced tool for landscape, architecture, portraiture, and still life rather than a body suited to fast-moving subjects.
Viewfinder, Screen, and Handling
The 0.5-inch OLED electronic viewfinder offers 3.69M dots of resolution with 0.77x magnification and 100% coverage, giving a large, accurate preview that suits careful compositional work. The 3.2-inch tilt touchscreen at 2.36M dots allows vertical angle adjustments for low or high tripod positioning, though it does not articulate fully. At 900 g with battery and card, and measuring 150.0 x 104.2 x 87.2 mm, the GFX 50S II is meaningfully smaller than the 100-series bodies, and users who come from the original GFX 50S note a considerable reduction in overall volume.
Storage, Connectivity, and Power
Dual SD card slots, both rated for UHS-II cards, accommodate buffer overflow, backup, or format-separated workflows. The USB-C 3.2 port supports fast file transfer and in-camera charging. Wireless connectivity covers Wi-Fi 4 (802.11n) and Bluetooth 4.2, enabling remote control and image transfer via the Fujifilm Camera Remote application, and the NP-W235 lithium-ion battery is the same unit used across several Fujifilm bodies, simplifying management for photographers already in the Fujifilm ecosystem.
Video Capability: A Clear Limitation
Video resolution tops out at 1080p up to 30 fps, recorded in MP4 or MOV containers. This is a significant constraint compared to competitors at similar price points, and compared to the GFX 100 II, which offers 4K and higher-resolution video options. The GFX 50S II is not a hybrid camera, and photographers whose workflow requires serious video output should look elsewhere; for photographers who shoot only stills, this limitation has no practical impact.
The G-Mount Lens Ecosystem
Fujifilm describes G-Mount glass as purpose-built for the resolution demands of the GFX sensor line, and independent optical reviews consistently reflect that characterisation. The ecosystem is smaller and more expensive than X-Mount, with no third-party manufacturers offering G-Mount options as of the camera's release date, but the available primes and zooms are designed specifically for the 51.4 MP and 102 MP GFX sensors. Prospective buyers should budget for G-Mount glass as a meaningful portion of total system cost, and Fujifilm's official GFX 50S II product page is the authoritative reference for current and forthcoming compatible lenses.
Image Processing and Film Simulations
The X-Processor 4 handles in-camera processing and enables Fujifilm's full range of Film Simulations, including Provia, Velvia, and Classic Chrome. Reviewers note that the ability to produce finished-looking JPEGs straight from camera reduces editing overhead for photographers who work in fast-turnaround commercial or editorial contexts. For those shooting in RAF (Fujifilm's raw format), the 51.4 MP files carry significant latitude in shadow and highlight recovery, as is characteristic of sensors with this physical size and pixel pitch.

The Ideal User for the GFX 50S II
Consensus indicates the GFX 50S II fits photographers who prioritise maximum still-image resolution and medium format tonal quality, shoot at a deliberate pace, and value in-body stabilisation for handheld medium format work. Landscape, architectural, fine-art, portrait, and product photographers are its natural constituency. Users report that the smaller body relative to the GFX 100 series makes it more practical for location work, particularly when combined with lighter G-Mount primes, while photographers who need fast autofocus, high burst rates, or capable video should look to other models.
Positioning and Value Within the GFX Lineup
At its retail positioning, the GFX 50S II is Fujifilm's most accessible route into the G-Mount system, offering a meaningful resolution and sensor-size advantage over the leading APS-C Fujifilm bodies (including the X-H2 and X-T5) while costing considerably less than the GFX 100 II. Photographers considering the X-H2 or X-T5 for resolution purposes should note that the sensor size difference between APS-C and medium format delivers rendering characteristics beyond what megapixel counts alone describe. The GFX 50S II occupies a distinct position: a true medium format camera with a body that remains practical for location photographers working outside a studio.
Frequently Asked Questions
- Does the Fujifilm GFX 50S II have in-body image stabilisation?
Yes. The GFX 50S II includes a five-axis in-body image stabilisation system. Fujifilm rates the compensation at up to 6.5 stops of shake reduction when used with stabilisation-compatible G-Mount lenses. This was a notable addition over the original GFX 50S and makes handheld shooting in lower light considerably more practical for a medium format body of this size and weight.
- What autofocus system does the Fujifilm GFX 50S II use and how does it perform?
The GFX 50S II uses a TTL contrast-detection autofocus system with 117 focus points, covering single point, zone, and wide/tracking modes. Contrast-detect AF is reliable and accurate in stationary or slow-moving subject scenarios, which suits the camera's core use cases in landscape, portraiture, and still-life work. Users consistently note it is slower than the phase-detect systems found in sports and action-oriented cameras, and it is not designed for tracking fast-moving subjects.
- Can the Fujifilm GFX 50S II shoot video?
The GFX 50S II records video at a maximum of 1080p (Full HD) at up to 30 fps in MP4 or MOV format. This is a significant limitation compared to cameras in a similar price bracket and compared to the GFX 100 II, which offers higher-resolution video recording. Photographers whose workflows require 4K or higher video output should consider other options, while for still-only photographers this specification has no bearing on the camera's primary capabilities.
- How does the GFX 50S II compare to the GFX 100 II?
The GFX 100 II offers approximately 102 MP, improved phase-detect autofocus, substantially better video capability, and higher burst rates, while the GFX 50S II is lighter, smaller, and less expensive. Both share the G-Mount lens ecosystem. The GFX 50S II is the appropriate choice for photographers entering the system on a tighter budget or who prioritise body portability, while the GFX 100 II suits those who need the highest available resolution or more capable video from the same system.
- What lenses are compatible with the Fujifilm GFX 50S II?
The GFX 50S II uses Fujifilm's G-Mount, which is exclusive to the GFX medium format system. All current G-Mount lenses from Fujifilm are compatible with the body. As of the camera's release date, no third-party manufacturers produce native G-Mount lenses, so photographers are limited to Fujifilm's first-party lens lineup. Fujifilm maintains an official G-Mount lens roadmap on its website, which is the authoritative reference for current and forthcoming compatible glass.
- Is the Fujifilm GFX 50S II weather sealed?
The GFX 50S II body features dust and moisture resistance, which aligns with its use cases in landscape and location photography. Full weather sealing effectiveness also depends on the attached lens, and photographers working in severe conditions should verify the weather resistance ratings of the specific G-Mount lens they intend to pair with the body. Fujifilm's official product specifications are the authoritative source for both body and lens weather resistance ratings.
- What memory card format does the Fujifilm GFX 50S II use?
The camera has dual SD card slots, both supporting UHS-II rated cards. UHS-II cards are recommended to keep pace with the large file sizes generated by the 51.4 MP sensor, particularly when shooting RAW in RAF format. The dual-slot configuration allows for overflow backup, simultaneous RAW plus JPEG shooting to separate cards, or video and stills separation depending on the photographer's preferred workflow.
