Digital Camera World Verdict

Designed for Sony’s APS-C format mirrorless E-mount cameras, this lens is effectively a 24mm f/1.8 optic in full-frame terms, delivering a wide field of view with a bright aperture. As such, it fits the bill perfectly with a compact and lightweight yet sturdy construction. And despite its low-budget selling price, it performs very well and has refined handling characteristics, making it a smart buy.

When is a 16mm lens not really a 16mm lens? Well, the Yongnuo YN16mm F1.8S DA DSM is designed for Sony’s APS-C format mirrorless E-mount cameras, so it has less of an ultra-wide viewing angle, corresponding to a more modest 24mm lens in full-frame terms. The giveaway is the ‘DA’ classification, compared with Yongnuo’s YN35mm, YN50mm and YN85mm lenses which have a ‘DF’ suffix, denoting full-frame compatibility.
