What we like about Panasonic Leica DG Summilux 9mm F 1 7 ASPH

  • Extremely compact and lightweight (approx. 130g), making it ideal for travel and vlogging.
  • Fast f/1.7 aperture provides excellent low-light performance and some background blur.
  • Impressive 'half-macro' capability with a very close minimum focusing distance of 9.5cm.
  • Fully weather-sealed (dust, splash, and freeze resistant) for reliable outdoor use.
  • Quick, quiet, and smooth autofocus performance, which is highly beneficial for video recording.
  • Minimal focus breathing and smooth aperture stepping designed specifically for videographers.
  • Strong center sharpness even when shooting wide open at f/1.7.

What we don't like about Panasonic Leica DG Summilux 9mm F 1 7 ASPH

  • Noticeable softness in the corners of the frame, which may not fully sharpen even when stopped down.
  • Construction is primarily high-quality plastic rather than the premium metal body found on some other Leica-branded lenses.
  • Significant native barrel distortion in RAW files that relies heavily on in-camera or software correction.
  • Lacks internal optical image stabilization (OIS), though this is often mitigated by camera body stabilization.
  • Some users find the bokeh quality to be 'fussy' or less attractive due to bright-edged circles.
  • Occasional longitudinal chromatic aberration (magenta/green fringing) can be visible in high-contrast scenes.

Verdict

The Panasonic Leica DG Summilux 9mm f/1.7 ASPH is a compact, ultra-wide-angle prime lens for Micro Four Thirds systems, offering an 18mm equivalent focal length and a bright f/1.7 aperture. It features a sophisticated optical design with 12 elements in 9 groups—including two aspherical and two ED elements—and boasts a remarkably close 0.095m minimum focusing distance with a 0.25x magnification ratio. Its primary strengths include its lightweight 130g weather-sealed construction, half-macro capabilities, and suppressed focus breathing ideal for video; however, its main drawbacks are noticeable barrel distortion and vignetting that require software correction, along with occasional flare when shooting directly into bright light.
