Third-party reviews

Based on 12 buyer reviews from online shops.
Reviews last updated: July 2026 · How we calculate this

What we like about Panasonic LUMIX DMC GF1 LUMIX G 20mm F1 7 ASPH

  • Ultra-compact and portable 'pancake' form factor ideal for travel and street photography
  • Superb image sharpness and resolution, especially in the center even at f/1.7
  • Bright f/1.7 aperture allows for excellent low-light performance and shallow depth-of-field
  • Solid, high-quality build with a magnesium alloy body and intuitive external controls
  • Versatile 40mm equivalent focal length that provides a natural, human-eye perspective
  • Fast and reliable contrast-detect autofocus (significantly better than early competitors)

What we don't like about Panasonic LUMIX DMC GF1 LUMIX G 20mm F1 7 ASPH

  • Lack of in-body or lens optical image stabilization, leading to camera shake in handheld video
  • Autofocus can be noisy and relatively slow compared to modern mirrorless standards
  • No support for continuous autofocus (C-AF) on this specific lens, making it poor for action
  • Limited dynamic range compared to contemporary DSLRs, with a tendency to clip highlights
  • Built-in flash is relatively weak, and an external viewfinder (EVF) must be purchased separately
  • Buffer fills up quickly (5-6 shots) when shooting RAW+JPEG pairs

Verdict

The Panasonic Lumix DMC-GF1 is a compact Micro Four Thirds mirrorless camera featuring a 12.1-megapixel Live MOS sensor and a 3-inch, 460,000-dot LCD screen. When paired with the Lumix G 20mm f/1.7 ASPH pancake lens, it offers a versatile 40mm equivalent focal length and a fast maximum aperture ideal for low-light photography and shallow depth-of-field effects. Key technical specs include a shutter speed range of 60 to 1/4000 second, 720p HD video recording in AVCHD Lite format, and a 23-point contrast-detection autofocus system. The camera's main strengths are its robust magnesium alloy build, rapid autofocus for its class, and pocketable form factor that provides a rangefinder-style experience. However, notable drawbacks include the lack of built-in image stabilisation, no integrated viewfinder (though an optional electronic one is supported), and an audible autofocus motor in the 20mm lens that can be picked up during video recording.
