Sony's APS-C ultra-wide zoom with OSS — 15-27mm equiv at constant f/4 for Sony E-mount.
The Sony E 10-18mm f/4 OSS launched in 2012 as a compact ultra-wide zoom for Sony APS-C E-mount, covering 15-27mm equivalent. The constant f/4 aperture and OSS stabilisation make it practical for handheld landscape and architecture shooting.
Optically good — sharp in the centre with reasonable edge performance for an ultra-wide. OSS stabilisation — unusual for an ultra-wide and genuinely useful. Constant f/4 maintains consistent exposure. Stepping motor AF for quiet operation.
Sony E mount with 62mm filter thread. Approximately 225g — incredibly light for an ultra-wide zoom. APS-C coverage. OSS stabilisation. Minimum focus distance 25cm. Internal zoom design.
Available used at mid-range prices. The OSS stabilisation is a unique advantage — most ultra-wides lack it. The Sigma 10-18mm f/2.8 DC DN is faster but larger. For Sony APS-C landscape and architecture shooters wanting stabilised ultra-wide.
