Also at Photokina, Fujifilm announced a new camera in their GFX series: the GFX 50R. The GFX 50R is to the GFX 50S what the X-E1 was to the X-Pro1: a more compact version of the 50 megapixel medium format mirrorless, in what they call a “rangefinder style” body (it is not a rangefinder camera). The GFX 50R also has a dual SD card slot. Available in November (2018) for US$4,500. DPReview has the details.
And to double it up, the announcement included news of the development of the GFX 100, a 100 Megapixel successor of the GFX 50S, to be released sometime in 2019, featuring phase detect auto-focus and in-body image stabilisation, as well as 4K video ! But will they solve the problems with such a large sensor? The price is speculated to be around US$10,000.
One more thing. According to The Verge, Fujifilm showed a XF 33mm f/1.0 R lens. F ONE POINT ZERO ! Coming in 2020.
