Our take on the Sony 20mm f1.8 G (SEL20F18G) Lens

The Sony 20mm f1.8 G is a compact wide-angle prime for Sony FE-mount mirrorless cameras. It pairs a fast f1.8 aperture with a 14-element, 12-group design, a 9-blade diaphragm and a close 0.18 m minimum focus distance, so it handles astrophotography, landscapes and close foregrounds in one lens. A weather-resistant body and a manual aperture ring suit stills and video shooters who want control in the field. It is small and light for an f1.8 wide prime, which is its main edge over larger, heavier ultra-wide zooms and faster wide primes.

Questions and answers

Is the Sony 20mm f1.8 G good for astrophotography?
Yes. The f1.8 aperture gathers light for night skies, and reviewers report good sharpness and controlled coma for a wide prime. Stop down slightly for the cleanest corners.
How close can it focus?
The minimum focus distance is 0.18 m, which lets you get close to a foreground subject for dramatic wide-angle shots.
Does it work on APS-C Sony cameras?
It mounts on E-mount APS-C bodies, where it gives roughly a 30mm equivalent field of view. It is designed for full-frame FE cameras.
Is it weather sealed?
Sony describes the body as weather resistant, with sealing against dust and moisture. It is not waterproof, so use care in heavy rain.
What is in the box?
The lens comes with front and rear caps, a lens hood and a soft case. Check the listing for the exact bundle.

The 20mm is wider, smaller and lighter, while the 24mm GM is faster and sharper wide open. Choose the 20mm for a wider view and a lighter kit.
