I am really excited about the Panasonic DMC GX1!
Anyways, GX1 is a 16 Mega Pixel camera (GF2 being 12MP) with ISO up to 12,800 (GF2: ISO 6400) with MFT sensor. It also has a Touch-Screen 3" TFT Display that allows you to do the "easy background DeFocus" & also the "Cool & Warm Colour selection".
If you are into taking videos, the GX1 lets you take Full HD videos at 30FPS & allows you to easily control your subject focus by touch on the screen. You can nw seamlessly take videos on the GX1!
Adding on, GX1 has a better grip compared to both GF2 & the GF3. You might have notice, a bigger hand grip is attached to the GX1, making it better to grasp for bigger hands like mine! Perhaps it is due to the bigger size ofGX1, I personally feel that holding a GX1 is better than holding the GF2 or the GF3.
Lastly, the GX1 is avaible in dual lens & "X" (14-42mm) lens kit. If you have not hear about the X lens, well, here is brief write up about the X Lens:
14-42 X lens is a power zoom lens - it is the size of a 20mm pancake lens but is able to zoom and be extended out. It has a nano surface coating which helps to reduce ghostings & flares. It also comes with a improved version of the Optical Image Stabliser (Mega O.I.S).
Last but not least, the GX1 is available in silver and black in power zoom lens kit & dual lens kit both price at RCP SGD 1299.
