Panasonic's tiny touchscreen mirrorless — 12MP Micro Four Thirds, Full HD video, built-in flash, 2011.
The Panasonic Lumix GF3 (DMC-GF3) was announced in June 2011 as the third generation of Panasonic's small GF line of Micro Four Thirds mirrorless cameras. At launch it was the smallest and lightest interchangeable-lens digital camera with a built-in flash, marking the GF series' shift from enthusiast tool to touchscreen-led everyday camera before the GF5 and GF6 continued the line.
It used a 12.1-megapixel Four Thirds Live MOS sensor with a faster processor enabling 120Hz-drive contrast autofocus, and recorded Full HD 1920x1080 video in AVCHD. Most controls ran through the 3.0-inch 460k-dot touchscreen, as the GF3 dropped the hotshoe and any viewfinder option. The body weighed about 264g with its proprietary 940mAh battery, rated around 320 shots per charge, and storage used SD/SDHC/SDXC cards.
The GF3 suits beginners and travellers wanting interchangeable lenses in a pocketable body, especially with a compact prime attached. Enthusiasts may miss physical dials, the hotshoe and viewfinder support, and the 2011-era sensor trails later Micro Four Thirds bodies in high-ISO work, but access to the full lens mount keeps it versatile.
Used checks should start with the touchscreen, which the camera depends on: confirm touch response across the panel. Test the pop-up flash, the mount release and lens communication with a native lens, and look for sensor dust in a sky shot. Batteries are proprietary, so check a genuine or decent replacement is included, and confirm the SD door and tripod thread are undamaged on these light plastic bodies.
