"Panasonic's Lumix DMC-GX1 is the company's latest addition to its G-series lineup. And although the camera bears the '1' appendage in its model name, it is clear from even a cursory glance that with the GX1, Panasonic has provided the long-awaited spiritual successor to the highly regarded Lumix DMC-GF1. Of perhaps even greater significance, the move to introduce a separate GX product line (as opposed to releasing the camera as a 'GF4') would seem to suggest a long-term commitment by the camera maker to meet the demands of enthusiasts who embraced the GF1.
Launched back in 2009, the GF1 was, ironically, Panasonic's attempt to court compact-camera owners looking to upgrade, with what was then billed as, 'the world's smallest, lightest interchangeable lens camera'. Instead, the GF1's high quality Raw output and classic rangefinder aesthetic gained a strong and passionate following in the enthusiast market. DSLR owners looking for a second 'go-anywhere' camera with high image quality embraced the camera's external control points and its relatively compact Micro Four Thirds lens offerings.
It is precisely these users who have been disappointed twice over with the Lumix DMC-GF2 and Lumix DMC-GF3 releases, which broke with the retro styling and button-driven operational control in favor of ever-smaller form factors and design cues that pointed unambiguously to users who may be turned off by an overly complex (and expensive) camera. With the GX1 Panasonic is taking square aim at more advanced users for whom the GF1 struck a pleasing balance between size and operability."
