The XF 16mm f/2.8 R WR is a 24mm-equivalent wide-angle lens, well-suited to landscape, nature, and architectural shooting. Its f/2.8 maximum aperture balances size and speed and is suitable for working in available lighting conditions while also limiting the overall size and weight of the lens for everyday use.  Complementing the optics is a stepping motor, along with an internal focusing design, which provides quick and especially quiet focusing performance. Additionally, the lens is weather-sealed to suit working in inclement conditions. Moderately bright f/2.8 maximum aperture suits working in available light conditions and also helps to maintain a compact form factor. Super EBC coating has been applied to individual elements to reduce lens flare and ghosting for improved contrast and color fidelity when working in strong lighting conditions. The lens body incorporates weather sealing to protect against dust and moisture, and to enable worry-free use in inclement conditions and freezing temperatures as low as 14°F.
