Viltrox AF 27mm f/1.2 Pro (APS-C)
One of the strongest picks in this batch, this enthusiast-tier APS-C prime is the brightest autofocus option in its class: a 27mm (40mm-equivalent) f/1.2 for serious low-light work, shipping in Fuji X, Sony E, and Nikon Z. It's for shooters who want maximum aperture and a fast everyday focal length. At 560g it dwarfs Fuji's own 27mm f/2.8, so compact street kits should look elsewhere, and full-frame bodies can't use its APS-C image circle.
