Panasonic Releases World’s First Micro Four Thirds Camera

Secaucus, NJ (September 12, 2025) – Panasonic today announced the world’s first Micro Four Thirds system camera, the LUMIX DMC-G1, the world’s smallest and lightest digital interchangeable lens camera, weighing in at approximately 385 grams (0.85 lbs).* Based on the new Micro Four Thirds System standard, the LUMIX G1 eliminates the internal mirror structure that defines digital single-lens reflex (DSLR) cameras, thus reducing the size and weight by nearly half.** With the mirror-less system, the G1’s flange back, which is the distance between the mount and the image sensor, has been reduced from 40 mm – as specified in the Four Thirds System – to approximately 20 mm.

The new Panasonic LUMIX DMC-G1 will enhance the advanced photo quality and flexibility made possible by the Four Thirds™ System, and with its innovative design, consumers will appreciate the portability of a smaller camera body and lenses. The G1 will be available in mid-November as a kit with the new LUMIX G VARIO 14-45mm/F3.5-5.6 ASPH/MEGA O.I.S lens. Also available in November, and announced today, is the LUMIX G VARIO 45-200mm/F4.0-5.6/MEGA O.I.S.lens.

“With the LUMIX G1, we are filling a void that has existed for a long time in the digital camera market because consumers wanted the power of an SLR, but previous models were bulky and inconvenient,” said David Briganti, National Marketing Manager, Imaging, Panasonic Consumer Electronics Company. “The LUMIX G answers this challenge as consumers can benefit from the flexibility of changing lenses; a quick Auto Focus; and a sensor that produces high-quality photos. By packing all those powerful assets into an extremely compact body with easy-to-use features familiar to point-and-shoot users, we are excited about G, as it brings new possibilities to the consumer.”

The LUMIX G1 is also the world’s first interchangeable lens camera that will come with color variety – with availability in black, blue and red models – allowing consumers to personalize their style through color, something very popular with point-and-shoot camera models.

For current Four Thirds users with a collection of lenses, an optional mount adapter will allow Four Thirds lenses to be compatible with the LUMIX G1.*** Also, today, with the introduction of the Micro Four Thirds System, Panasonic is announcing a wide-variety of accessories including: External Flash DMW-FL220(GN22); PL Filter: DMW-LPL52; Mount Adapter: DMW-MA1; Battery Pack: DMW-BLB13; DC Cable: DMW-DCC3; Soft Case: DMW-CG1; Soft Bag: DMW-BAG1; Shoulder Strap (Stylish) DMW-SSTG1-A/C/R; Shoulder Strap (Woven) DMW-SSTG2-W; Shoulder Strap (Leather) DMW-SSTG3-T.
