What this lens is good for
Versatile walkaround wide
A 16-50mm full-frame equivalent that stretches from ultra-wide to normal in one weather-sealed lens, so it doubles as a walkaround rather than a dedicated ultra-wide. It takes standard filters and focuses close, making it unusually flexible for a wide zoom. Full guide →
Travel and street
The single-lens range from wide landscapes to normal street scenes suits travel, where carrying fewer lenses matters. The constant f/4 aperture is slower than the f/2.8 options, so it is less suited to low light and astro, but the versatility and sealing are strong for general use.
