COLOGNE (GERMANY) - As more camera makers join full-frame mirrorless camera bandwagon, Japanese imaging giant Fujifilm upped the ante when it announced new medium-format mirrorless cameras in GFX 50R and a concept flagship model GFX 100 a day before the start of Photokina 2018 - the world's largest camera trade show.

The Fujifilm GFX 50R is not an immediate successor to last year's medium-format mirrorless camera GFX 50S. Rather, the R stands for rangefinder.

The GFX 50R sports a more traditional rangefinder design that is 25mm thinner and 145g lighter than the GFX 50S. But it uses the same 51.4-megapixel medium-format (43.8mm x 32.9mm) image sensor and X-Processor Pro image processor as the GFX 50S.

In addition, the GFX 50R retains the same solid build and weather-sealing as well as features a 3.69-million-dot electronic viewfinder, 3.2-inch touchscreen display and dual SD card slots with support for UHS-II cards. The GFX 50R will be available in Singapore in Nov for $6,999 (body only).

At the same time, Fujifilm also announced the development of a mouth-watering 100-megapixel medium-format mirrorless camera - GFX 100. It will be equipped with a whopping 102-megapixel medium-format image sensor and Fujifilm's fourth-generation X-Processor 4.

Fujifilm claims that GFX 100 will be the world's first medium-format mirrorless camera to feature an image sensor with phase detection pixels across the entire sensor, in-body image stabilisation system and 4K video recording.

Previously, Fujifilm is famed for its X-series APS-C mirrorless cameras. But it looks like Fujifilm is giving full-frame the miss and moving towards medium-format instead.
