Inside Fuji’s first compact system camera (CSC), the Fuji X-Pro1, is a 16.3 million pixel X-Trans CMOS that produces images of up to 15.89MP.
This means that when images are printed at 300ppi, they are just a small fraction short of full A3 size – ideal for most enthusiast photographers.
Although this sensor is APS-C sized, Fuji claims that its cunning design enables the X-Pro1 to produce images that are superior to those from a full frame DSLR like the Canon EOS 5D Mark II or Nikon D700.
The secret is in the arrangement of the pixels.
Unlike most cameras that use a Bayer pattern of red, green, green and blue receptors (usually referred to as RGGB) arranged in a 2 x 2 grid, the X-Trans CMOS device uses a 6 x 6 RGGB filter array pattern, with a random arrangement of colour filters within each block of 36 photo receptors.
Fuji claims this avoids the issue of moiré patterning, which can occur as a result of the fine grid structure that makes up the average Bayer pattern sensor.
As a result, Fuji hasn’t fitted X-Pro1 with an anti-aliasing filter, which means it should be able to produce sharper images from the outset.
The Fuji X-Pro1 is the brand’s first interchangeable lens camera since the Fuji FinePix S5 Pro, which dates from September 2006. While the S5 Pro is a DSLR that accepts Nikon F-mount lenses, the Fuji X-Pro1 is a compact system camera debuting Fuji’s X mount.
