Sony FE 14mm F1.8 GM

4.8

$1,698as of Jun 7

The FE 14mm F1.8 GM is an exceptionally compact and light ultra-wide prime that punches well above its size. It is razor-sharp from f/1.8, controls coma well enough for serious astrophotography, and weighs a fraction of competing 14mm lenses. The trade-offs are the fixed focal length, the rear-only filter system, and a premium price for a specialist angle of view.

Strengths

— Outstanding center sharpness wide open at f/1.8, holding through f/11
— Remarkably compact and light for the class at 460g, far smaller than rival 14mm primes
— f/1.8 ultra-wide aperture is a serious tool for Milky Way and astro work

Watch-outs

— Bulbous front element means no front filter thread; uses a rear filter holder only
— Some wavy distortion that benefits from the correction profile
— Fixed 14mm focal length offers no framing flexibility

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

Tamron 17-28mm F2.8 Di III RXD

4.6

$899as of Jun 7

The Tamron 17-28mm F2.8 Di III RXD is the value champion of fast Sony wide zooms. It combines near-G-Master center sharpness with a genuinely pocketable 420g body and a constant f/2.8 aperture, all for under $900. The compromises are a narrower zoom range and slightly soft close-focus corners, but as a light, weather-sealed travel wide-angle it is hard to fault.

Strengths

— Center sharpness rivals and at times matches the Sony G Master, especially on distant subjects
— Exceptionally compact and light at 420g and about 10cm long
— Constant f/2.8 aperture at less than half the price of the Sony GM II

Watch-outs

— Restrictive 1.6x zoom range that stops at 28mm rather than 35mm
— Full-frame corners can be a bit soft at close 1-2m focus distances
— Very short working distance at the wide end limits close-up framing

How they stack up

Sony FE 14mm F1.8 GM

It goes wider and brighter than any zoom here, including the Sony FE 16-35mm F2.8 GM II, making it the astro and low-light specialist of the group. Compared with the Sony FE 20mm F1.8 G it is wider and pricier but loses the front filter thread. The fixed 14mm view is the trade-off versus flexible options like the Tamron 17-28mm F2.8 Di III RXD.

Tamron 17-28mm F2.8 Di III RXD

It is the lightest and one of the cheapest fast zooms here, undercutting the Sony FE 16-35mm F2.8 GM II by roughly $1,400 while matching much of its center sharpness. Against the Sigma 16-28mm F2.8 DG DN Contemporary it is similar in concept but starts at 17mm rather than 16mm and uses a 67mm rather than 72mm filter. Unlike the Sony FE 14mm F1.8 GM and FE 20mm F1.8 G primes, it offers a zoom range, albeit a short one.
