The Panasonic Lumix DMC-GF1 is a Micro Four Thirds, interchangeable lens mirrorless camera. It includes a 12.1 megapixel sensor, which can operate at an ISO range from 100 to 3200. Among its many features is a sophisticated facial recognition capability which can even be trained to recognize faces you photograph often.
The camera features a spartan, but attractive design and fits comfortably in the hand. While small and lightweight, it is capable of excellent images and for most uses, excels.
The basic Panasonic Lumix DMC-GF1 kit comes with a battery, charger and image processing software. Two kit versions of the camera are available, one comes with the 20mm 1.7 lens, the other with the 14-45mm zoom lens. Both versions run somewhere around $800 at this point. I bought mine used off of eBay since I didn't want to buy the kit. I have to buy the cameras I write about for these user guides I mentioned previously, so I have to shop as carefully as Bright Hub readers do for this gear.
Since I already had the Olympus E-P2 and several lenses for it, I wanted to take some time before buying a Panasonic lens or two. Once of the really nice features of the whole Micro Four Thirds approach is that lenses are interchangeable between systems (with varying degrees of compatibility depending on whether you're using a Four Thirds system lens or Micro Four Thirds system lens). I did eventually end up buying the 20mm 1.7 and 14-140 Panasonic lenses. I also purchased lens adapters so I could use Nikon and Canon EOS mount lenses on my Micro Four Thirds cameras.
