Fujifilm X-Pro1 review. The X-Pro1 is Fujifilm's first mirrorless interchangeable lens camera and it aims straight for the high-end camera enthusiast as the equally classically-styled X100 before it. However, far from simply being a 16MP X100 with interchangeable lenses, the X-Pro1 also features characteristically adventurous Fujifilm technology: a X-Trans CMOS sensor. This uses a non-standard color filter array which promises less susceptibility to moiré, avoiding the need for a low-pass filter - promising sharper images. Fujifilm has announced an impressive XF lens roadmap, so is it done justice by the first X-mount body?
