From the review: "
Aimed at advanced enthusiasts, the Panasonic Lumix DMC-GX1 is designed to fill the void left by the acclaimed Lumix DMC-GF1, which sported a level of manual functionality that photographers missed with the subsequent launches of replacements; the Lumix GF2 and Lumix GF3. Could the flagship model of Panasonic's brand
new GX series be the best G-system camera to date?
At the heart of the Panasonic Lumix DMC-GX1 beats the same 16MP Four Thirds Live MOS sensor that was incorporated into the Panasonic G3, along with Panasonic's advanced Venus Engine VII HD processing engine that we saw in the GF3. The G3 impressed in the image quality department, so it stands to reason that the GX1 should be capable of putting in a similar performance."
Before we go on to the main dish, here's a reader commentary on the same Engadget page:
"Why does everyone simply forget panasonic G3? It has the same sensor as GX1, marginally bigger body but with EVF builtin, an extremely handy tilted screen with touch focus and same resolution as gx1. It's basically the same or even better than GX1!!
These "short & sharp" reviews are pretty amazing, they reallt live up to their name:
"A short, sharp review of the GX1, Panasonic's mirrorless system camera for the discerning enthusiast. Tested alongside the Sony NEX-5N to see which one comes out on top. View at 1080p to see sample shots at 1:1 pixel ratio."
Stuff-Review has made a nice little chart that pits the newcomer against the almost established crowd. That's all pretty theoretical though, since 3 of the 4 cameras are practically not available in the majority of the western world:
