Fuji specifically wanted to target professionals and enthusiasts with its X line, so it first introduced a professional-level mirrorless camera, the X-Pro1, along with three prime lenses: Fuji XF 18mm f/2, Fuji XF 35mm f/1.4 and Fuji XF 60mm f/2.4 Macro. And hence, being part of the Fuji X mirrorless interchangeable lens system launch, the Fuji 35mm f/1.4 played a big role in the success of the product line.
Thanks to its compact size, a fast aperture of f/1.4 and a versatile focal length, the Fuji 35mm f/1.4 undoubtedly became the most popular of the three lenses.
