The Fujinon XF 27mm F2.8 is an interchangeable camera pancake lens announced by Fujifilm on June 25, 2013. At 27 mm, it has a 35 mm equivalent focal length of 41 mm, making it a normal lens of maximum aperture f/2.8. The intended benefit of this lens is its extreme compact size, extending only 23 mm (0.91 in) from the flange, and light weight, only 77.3 g (2.73 oz), with the trade-off of having no aperture ring.
In 2021, an updated version of this lens called the XF 27mm F2.8 R WR was released. It has the same length and optical construction as the original, while adding an aperture ring (R) and weather resistance (WR).
