Canon 16mm f/2.8 RF STM (5051C005)

Small wide-angle fixed lens for full-frame Canon mirrorless cameras with RF mount. It has a wide diagonal field of view (about 107°) and a quite acceptable maximum aperture of f/2.8. The model is useful for landscape, interior, and architectural photography genres. Thanks to its silent stepper motor autofocus, it is also suitable for video shooting. The lens focuses automatically from a distance of 13 cm.

Optically, the Canon RF 16mm f/2.8 STM is designed with 9 elements in 7 groups, with one lens being aspherical. The aperture is a traditional 7-blade type, without claiming outstanding bokeh beauty. However, this is not critical for wide-angle optics. The fixed lens is compatible with small and therefore relatively inexpensive filters with a diameter of 43 mm. The "wide" is housed in a body with dimensions of 40x69 mm (diameter and length respectively) and weighs about 165 g. When carried with camera equipment, the lens takes up minimal space and hardly adds any weight.
