Leapfrogging the more conventional full-frame formats of most companies, Fujifilm has made a daring leap into the medium format realm with the introduction of its GFX camera system. The star of this show is obviously the large 43.8 x 32.9mm 51.4MP CMOS sensor at the heart of the GFX 50S Mirrorless Camera. This is going to produce incredible images with outstanding color and detail. Along with this camera, Fujifilm developed the G mount with a short flange distance of 26.7 mm, meaning your older medium format lenses can be adapted. And for fans of native lenses, a series of six GF lenses will be available.
To take full advantage of the medium-format sensor, Fujifilm has used the X-Processor Pro image processor to deliver Fujifilm’s signature color and tonal reproduction, as well as deliver images with fine detail. The sensor is also versatile, with multiple aspect ratios to select, including 4:3, 3:2, 1:1, 4:5, 6:7, 6:17. The camera’s design takes a great deal of its DNA from Fujifilm’s smaller X-series cameras, such as dust- and weather-resistance, cold resistance to 14°F, many physical buttons and dials, and a lighter, more compact form factor than comparable models, but it takes many more steps that make it a professional choice. The highlight feature in this aspect is the detachable electronic viewfinder, which can even accept an optional adapter for using the EVF in multiple positions and angles, and it will come with support for tethered shooting.
While not many details are available yet for the GF lens lineup, Fujifilm did provide a comprehensive list of the first six options. This includes a GF 63mm f/2.8 R WR equivalent to 50mm, a wide-angle GF 32-64mm f/4 R LM WR equivalent to 25-51mm, a short telephoto GF 120mm f/4 Macro R LM OIS WR with 2:1 magnification that is equivalent to 95mm, a fast GF 110mm f/2 R LM WR equivalent to 87mm, an ultra-wide GF 23mm f/4 R LM WR equivalent to 18mm, and a GF 45mm f/2.8 R WR equivalent to 35mm. All of these lenses will incorporate a physical aperture ring and a C Position on the ring for adjusting the aperture with the camera body. They are all dust- and weather resistant, as well, and will function in temperatures as low as 14°F.
