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.

UPDATE: our testing team has posted their full Fuji X-Pro 1 review over at TechRadar. They like. They really like!

The Fujifilm X Pro 1 compact system camera has beaten the Leica M9 and some of the top full frame DSLRs, including the Canon EOS 5D Mark II, in resolution tests conducted by our testing team.

When the Fuji X Pro 1 was announced back in January, a ripple of disbelief spread around the globe after Fuji claimed that its APS-C sized sensor was capable of producing better results than full-frame cameras.

It does this by arranging the colour filters in a way that allows for the low-pass filter to be removed.

Naturally, the team here at Digital Camera world was very excited to receive the X-Pro 1 so we could put it through our rigorous testing to see if it managed to live up to the hype.

We are extremely pleased to report that the X Pro1 doesn’t disappoint.

Our analysis pitted the Fuji camera against the full-frame Leica M9 and two full frame DSLRs: the Canon EOS 5D Mark II and Nikon D700.

Shot using the Fujinon XF60mm f/2.4 Macro lens, it was only the 5D Mark II that had a better signal to noise ratio result for raw files.

Our testing team has also been out shooting real world images with the X Pro 1, and again we have been pleased with the initial results.

We will be putting the camera through even more extensive testing over the coming days, to bring you a full in-depth analysis. In the meantime you can read the Hands On: Fuji X Pro1 review by our testing team over on our sister site TechRadar.

As soon as we are able we will compare the X-Pro1 with the latest generation of full-frame DSLRs, the Canon 5D Mark III and Nikon D800.
