The XPro1 uses a newly developed 16MP APS-C CMOS sensor Fujifilm is calling the X-Trans. The main difference over existing designs is the colour filter array. Fujifilm explains that an optical low-pass filter is typically used to reduce moiré and false colour, but the filter also degrades resolution. The company’s new colour filter array tries to mimic the randomness that occurs in film grain, which eliminates moiré and false colour but also the need for the optical low-pass filter. The net result is accurate colour without artifacts or losses in sharpness.
The camera builds on the innovative Hybrid Viewfinder introduced in the X100. The optical part is stepped to give the correct framing with lenses of different focal lengths, plus the electronic viewfinder is always available.
Fujifilm has also announced three fast prime XF Fujinon prime lenses that will be available: the XF18mmF2 R (27mm equivalent) f/2.0, XF 35mmF1.4 R (53mm equivalent) f/1.4, and XF60mmF2.4 R Macro (90mm equivalent) F/2.4, with more lenses promised later in the year.
The XPro1 will be available next month. Prices haven’t yet been announced.
