Fujifilm
The Fujifilm XF 27mm f/2.8 R WR is a tiny pancake prime designed to keep Fujifilm X-series kits extremely compact while offering a natural, slightly wide field of view on APS-C bodies (roughly a 40mm equivalent on full-frame). Its minimalist optical formula and featherweight construction make it ideal for photographers who prioritise pocketability and discretion — street shooters, travellers and anyone who wants a near-invisible lens on their camera. Despite the diminutive size the lens can deliver pleasing centre sharpness and controlled aberrations for everyday use, and its simple design tends to keep flare and internal reflections low. There is no built-in image stabilisation and the maximum aperture of f/2.8 is modest, so the lens depends on modern camera bodies and careful technique for very low-light work; however its small size and low weight reward photographers who value mobility over outright speed. The XF 27mm pairs well with compact Fujifilm bodies to produce an X100-like handling experience with interchangeable optics, and it serves as a convenient, unobtrusive normal/short-wide option for reportage, candid portraits and daily urban shooting where carrying less gear truly matters.
