7Artisans AF27F28-E 27mm
The 27mm f/2.8 lens on APS-C Sony E-mount delivers a 40mm-equivalent field of view, housed in a 173-gram all-metal body with hybrid autofocus and a 52mm filter thread. Its de-clicked aperture ring allows silent, smooth iris transitions, making it particularly useful for video despite the six-blade diaphragm. Best for street photographers and casual videographers needing a lightweight, everyday prime—not suited for close-up portraits given its 20.2 score in that category.
