10–18mm · f/4
The Sony E 10-18mm F4 OSS is a compact, lightweight ultra-wide zoom for APS-C E-mount cameras, offering a constant f/4 aperture and optical stabilization. Optical strengths include excellent center sharpness at 10mm f/4, with edges improving at f/5.6, though performance drops at 14mm wide open. Weaknesses include occasional autofocus hunting in low contrast or dim light. Build is metal and dense, but some note plastic parts. It suits landscape, architecture, and vloggers needing a wide, stabilized lens.
