Lumix is Panasonics brand of digital cameras, ranging from pocket point-and-shoot models to digital SLRs. Many Lumix models are fitted with Leica (Leica Camera) lenses that have been designed by Leicas German optical engineers and are assembled in Japan, some are rebadged as Leica cameras with different cosmetic styling. Leica had a similar relationship with Minolta in the past, where late model Leica SLRs (and some 35mm point and shoot models) were strongly based on Minolta bodies.

Most Lumix cameras use different releases of the Panasonic Venus Engine for digital image processing; the original version was followed by II, III, IV, HD (2008), V (2009), and VI, HD II (2010).

Panasonic produces all of Leicas branded digital point and shoot cameras in Japan, but not film cameras, the Leica M8 or Leica M9 digital rangefinder cameras, or the Digital Modul R digital camera back for the Leica R9 film SLR (Single-lens reflex camera).
