Sony FE 14mm F1.8 GM vs Tamron 17-28mm F2.8 Di III RXD

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 (4.8 vs 4.7). 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.

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

Ranked #3 in Best Wide-Angle Lenses for Sony E-Mount

Tamron 17-28mm F2.8 Di III RXD

4.7

$899

The Tamron 17-28mm is the value champion. At $899 it's less than half the Sony FE 16-35mm GM II's price, with image quality that holds up at every focal length except the missing 28-35mm range. For landscape, astro, and architecture shooters who don't need the GM II's edge-case features, this is the right Sony E-mount wide zoom buy. Lighter than the Sony GM II by 127g and far cheaper than every other pick in this lineup.

Strengths

— 420g — 23% lighter than the Sony FE 16-35mm GM II at less than half the price
— 67mm filter size accepts standard filter kits (vs Sony GM II's 82mm)
— Excellent corner-to-corner sharpness with virtually no color fringing

Watch-outs

— 17-28mm range is narrower than the Sony GM II's 16-35mm
— RXD motor is slower-focusing than Sony's XD Linear motors in the GM II
— Build quality feels less premium than the Sony GM lenses

How they stack up

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.

Tamron 17-28mm F2.8 Di III RXD

Best value pick. Narrower zoom range than the Sony FE 16-35mm GM II (17-28 vs 16-35) but at less than half the price. Compared to the Sigma 16-28mm, slightly less wide on the short end but similar pricing and build philosophy. Less focal flexibility than the Sony GM II but lighter and cheaper.
