Description and Reviews

Key Take-Aways:

The Lumix S 18mm f/1.8 is a weather-sealed 340 g ultra-wide prime with a 67 mm filter thread; it focuses quickly and quietly, shows minimal focus breathing for video, and matches Panasonic’s compact F1.8 prime series.  Professional reviews report very good sharpness (especially centrally), quick AF, low distortion/CA and strong video behavior, while noting obvious vignetting at f/1.8, some flare in backlight, reliance on software corrections, and comatic aberration wide open that makes it less ideal for astrophotography unless stopped down.  As of Sep 21 2025, user sentiment is broadly positive. Owners like the portability and video-friendly breathing control, with recurring comments about astro coma and softer corners or vignetting wide open. 

From Panasonic:

A large-diameter prime lens compatible with all L-Mount cameras for maximum versatility, quickly and easily exchangeable with others in the series of F1.8 lenses when on a gimbal. Rugged dust/splash-resistant* design and common filters can be used. The S-S18 excels in video recording performance with suppressed focus breathing, together with a micro-step aperture control for smooth exposure change

  • F1.8 large aperture lens provides high resolution from center to corner and beautiful bokeh; works with all L-mount full-frame digital cameras
  • The S-S18 has a similar angle view to what you see with your naked eye, for natural-looking close-up shots with a minimum focusing distance of 0.18m
  • Excels in video recording, with minimal focus breathing and smooth aperture control
  • Compact, portable lens is easy to carry all day in comfort; dust/splash*/freeze-resistant design withstands heavy field use under harsh conditions
