Panasonic LUMIX DMC GF1 LUMIX G 20mm F1 7 ASPH Avis | 108 Données comparées

The Panasonic Lumix DMC-GF1 is a compact, high-quality mirrorless camera featuring an exceptionally fast contrast-detect autofocus system, robust all-metal build quality, and an intuitive control layout. It delivers excellent raw image sharpness, supports 720p HD video, and features a bright 3-inch LCD, making it a powerful yet portable, DSLR-like, interchangeable lens option. However, the camera is limited by a flawed default JPEG engine that produces poor color, particularly in blue skies, and lacks in-body image stabilization, forcing reliance on lens-based stabilization.
