The Sigma 16mm f/1.4 DC DN Contemporary is a high-performance wide-angle prime lens designed for Canon EF-M mirrorless cameras. Featuring an ultra-fast f/1.4 maximum aperture, this lens excels in low-light conditions while delivering exceptional control over depth of field. Weighing just over 400 grams, the lens combines outstanding optical performance with a compact, lightweight design ideal for travel and portable photography. The 16 elements in 13 groups include aspherical and low-dispersion glass elements that minimise optical aberrations and deliver sharp, clear images across the entire aperture range. A stepping motor provides smooth, quiet autofocus perfect for both photography and videography, whilst the SuperMulti-Layer Coating reduces flare and ghosting for high-contrast results even in backlit conditions. The lens features a 9-blade rounded diaphragm for attractive background blur and includes a large petal-type lens hood. Digital optical correction is compatible with supported cameras, and the brass bayonet mount combines precision with rugged construction.
