Sony FE 20mm f/1.8 G

Name: FE 20mm f/1.8 G
Brand: Sony
Availability: InStock

The Sony FE 20mm f/1.8 G delivers a uniquely wide f/1.8 aperture in a compact, lightweight package — making it one of the most capable ultra-wide primes available for full-frame Sony shooters. Exceptional corner sharpness, minimal distortion, and close focusing to 0.19m make it equally at home for astrophotography, landscape, and environmental portraits.

GearFrame's Take

A remarkably compact ultra-wide prime — f/1.8 at 20mm in a travel-friendly package with outstanding optical quality.

📝 How suitability scores are calculated GearScore™ genre scores are calculated from this camera's verified specifications — autofocus, sensor, weight, weather sealing and more — weighted by what matters for each type of photography. Where a spec sheet misses something (e.g. a manual-focus rangefinder for street), we apply a documented editorial adjustment. Scores are not based on customer reviews. See our full methodology →
