Sigma 10-18mm f/2.8 DC DN Contemporary Lens Sony E

The Sigma 10‑18mm f/2.8 DC DN Contemporary Lens for Sony E is a compact, constant‑aperture ultra‑wide zoom designed specifically for APS‑C Sony E‑mount cameras (e.g., α6100, ZV‑E10, etc.).

Key specs and features

Focal range & coverage: 10–18mm with an effective full‑frame equivalent of about 15–27mm on APS‑C, giving a very wide field of view ideal for landscapes, interiors, and architecture.

Aperture: Constant f/2.8 across the zoom range, which gives strong low‑light performance and some background separation for such a wide lens.

Size and weight: Roughly 62 mm long, 72.2 mm in diameter, about 260 g, making it one of the smallest and lightest F2.8 ultra‑wide zooms for APS‑C systems.

Image quality and optics

Optical design: 13 elements in 10 groups, including 3 FLD, 1 SLD, and 4 aspherical elements to help correct aberrations and keep distortion and vignetting reasonably controlled for an ultra‑wide zoom.

Sharpness and bokeh: Sharp across much of the frame at common apertures, with a 7‑blade rounded diaphragm that produces relatively smooth, though not creamy, bokeh for a wide lens.

Use cases and handling

Ideal for: Landscapes, travel, interiors, street photography, and vlogging, where you want to capture both subject and environment in a tight space.

Video and AF: Designed around APS‑C mirrorless bodies and supports functions like electronic image stabilization, AF+MF, and DMF on compatible Sony E‑mount cameras, and can be paired with Sigma’s 18–50mm f/2.8 for a lightweight, constant‑aperture stills‑video kit.
