Panasonic Lumix DMC-GX1 Hands-on Preview

	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. Of course, the competition for these users has grown much stiffer today, and Panasonic recognizes that if it wants to expand the camera's appeal, the GX1 must offer advantages not only to the GF series but to a crowded market that includes strong APS-C sensor competition from both Sony and Samsung. In this regard, the GX1 employs a 16MP sensor that we have been led to believe is identical to the chip recently seen in the Lumix DMC-G3, although it is now being pushed to a top ISO of 12,800. A brand new viewfinder, the LVF2 has been introduced alongside the GX1. With a higher magnification and resolution, the LVF2 is a noticeable improvement over its predecessor, the LVF1. Crucially though, a new spec and connector makes the LVF2 incompatible with any GF models; neither is it possible to fit the LVF1 on the GX1. Faster communication between the camera and lenses helps the GX1 focus even faster than the 120Hz sensor readout allowed in the recently released G3 and GF3 models, with Panasonic claiming a 10% improvement. Panasonic's well-regarded touchscreen interface has also gotten some new tricks, with a level gauge and clever Touch Tab icon that allows you to hide, reveal (and of course activate) a small panel of menu options directly on-screen. Another very welcome feature is the inclusion of an orientation sensor that automatically rotates vertical images even when captured with non-OIS lenses. The GX1 is being made available in both black and silver bodies. Unlike previous GF models, none of the GX1's kit options includes a fixed focal length lens. Instead, the kit lens options are limited to just two; the Lumix G X Vario PZ 14-42mm F3.5-5.6 ASPH Power OIS zoom lens and the more conventional (and less expensive) Lumix G Vario 14-42mm F3.5-5.6 ASPH OIS lens. By creating a separate product line for the GX, Panasonic has by implication made clear that it sees significant growth potential in its GF lineup among compact-camera upgraders. With the GH2 appealing to users who shoot a lot of video and the G3 designed for (primarily) still shooters who desire a built-in EVF and articulated LCD, the GX1 is rather sensibly positioned as an enthusiast offering for those who want the highest image quality from a Micro Four Thirds camera, in a form factor that comfortably accommodates a range of zoom lenses and does not skimp on external controls.
	Panasonic GX1 specification highlights
	16MP Micro Four Thirds sensor ISO 160-12,800 Orientation sensor (providing information with non-OIS lenses) 3.0", 460k dot LCD Full AVCHD 1080/60i video (from 30fps sensor output) Continuous shooting up to 20fps (at reduced resolution) Electronic level gauge Four available Fn buttons (two onscreen)
	Differences between the GX1 and the GF1
	Higher resolution sensor (16MP vs 12MP) Touchscreen interface Top ISO of 12,800 (vs 3200) AVCHD 1080/60i video (vs 720p AVCHD Lite format) Stereo mic Electronic level gauge Two additional Fn buttons Compared to the Samsung NX200
	The Panasonic DMC-GX1 is taller than the Samsung NX200, which actually houses a larger APS-C sensor. The GX1's mode dial sits atop the camera plate as opposed to the recessed profile found on the NX200.
	From this top view you can see that the GX1 packs more control points along the camera's top plate, which maintains a traditional rangefinder-inspired shape compared to the more aggressively contoured design of the NX200. http://www.dpreview.com
