ソニー FE 20mm F1.8 G (SEL20F18G)

The weight distribution is so well-balanced on my mirrorless body that I barely notice it's there, even on a long hike. I was honestly shocked at how sharp stars look wide open at F1.8, with almost no coma in the corners.

The autofocus is whisper-quiet and locks on instantly, even in low light. Tack-sharp images at f1.8 with beautiful bokeh for a 20mm—it’s a fantastic walk-around lens for landscapes and astro.

Opens up sharp even at f/1.8, which surprised me for a wide-angle, and the whole thing barely adds any weight to my bag. The corners stay crisp right out to the edges, so landscapes just pop. Honestly, I've stopped reaching for anything else on hikes.
