Sigma 16-28mm F2.8 DG DN Contemporary vs Sony FE 14mm F1.8 GM

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Sony FE 14mm F1.8 GM comes out ahead by a narrow margin (4.6 vs 4.8). The gap is mostly about astrophotographers, architecture shooters, and landscape photographers who specifically need an ultra-wide prime with bright aperture — read the strengths below before deciding.

Ranked #4 in Best Wide-Angle Lenses for Sony E-Mount

Sigma 16-28mm F2.8 DG DN Contemporary

4.6

$899

The Sigma 16-28mm is the value zoom with the same 16mm wide end as the Sony GM II. At 450g and $899 it competes directly with the Tamron 17-28mm — and the deciding factor is usually filter compatibility and the matter of an extra millimeter wide vs an extra few millimeters tele. Inner zoom design is a real advantage for gimbal users. Image quality is excellent throughout the range, sharper than expected at the corners.

Strengths

— 450g weight with inner zoom design — center of gravity stays constant for gimbal use
— 16mm wide end matches the Sony FE 16-35mm GM II
— Five FLD elements and four aspherical lens elements for sharpness

Watch-outs

— 16-28mm range is narrower than the Sony GM II's 16-35mm
— Shorter zoom range than the Tamron 17-28mm by 1mm at each end (effective)
— Sigma's Contemporary line is positioned below the Art line in build quality

Higher ratedRanked #2 in Best Wide-Angle Lenses for Sony E-Mount

Sony FE 14mm F1.8 GM

4.8

$1,598

The 14mm f/1.8 GM is the astrophotography and ultra-wide specialist. F/1.8 at 14mm focal length is rare — that combination captures dim Milky Way detail and night-sky scenes with shutter speeds and ISOs that competing slower lenses can't match. The 460g weight is unusual for this spec class. Trade-off is the fixed focal length — a one-perspective lens — and the curved-front-element design that rules out front-threaded filters.

Strengths

— F1.8 at 14mm — brightest ultra-wide for Sony E-mount, ideal for astrophotography
— 460g weight is remarkable for an f/1.8 ultra-wide G Master prime
— Excellent sharpness from corner to corner even at f/1.8

Watch-outs

— Fixed 14mm focal length — primes vs zooms is a fundamental design tradeoff
— Curved front element means rear gelatin filters only — no front threads
— Expensive vs the Tamron/Sigma zoom alternatives

How they stack up

Sigma 16-28mm F2.8 DG DN Contemporary

Direct competitor to the Tamron 17-28mm at the same price. Wider on the short end (16mm vs 17mm), narrower on the long end (28mm). Inner zoom design is the differentiator vs the Tamron for video and gimbal work. Less expensive than the Sony FE 16-35mm GM II by ~$1,400.

Sony FE 14mm F1.8 GM

Brightest aperture in this lineup at f/1.8. Less versatile than the Sony FE 16-35mm GM II zoom; comparable to the Sony FE 20mm f/1.8 G but wider. Ultra-wide-only — the Tamron and Sigma zooms cover 16-28mm/17-28mm but only at f/2.8.
