Four Thirds cameras compared (JPEG, default)
Before we move on let's take a quick look at how the G-F1 compares with the other two Micro Four Thirds cameras (the Panasonic GH1 and Olympus E-P1) - and the nearest Four Thirds camera, ...
Micro Four Thirds (Olympus, Panasonic)
Olympus M. Zuiko Digital 45mm f/1.8 Lens ($400)
Built from the ground up as a portrait lens, the Olympus 45mm f/1.8 lens offers pleasing background blur at its widest aperture.
Micro-four thirds lenses
The Panasonic 8mm fisheye lens is a great option for wide-angle. Most people use the kit lens with a wet macro lens for everything else. The Panasonic 45mm macro lens is a sharp, but expensive macro lens.
[edit] Four Thirds System
The Four Thirds System was created by Olympus and Kodak in 2001, and is designed exclusively for digital cameras.
Popular Four Thirds Cameras
I decided to add this category of cameras last quarter in as it continues to gain popularity. There isn't a lot of cameras to chose from but here are the 3 that we saw sold.
Four Thirds sensor leads to more compact bodies and lenses, reducing the bulk build inherent in wrapping the system in a housing.
All Olympus bodies incorporate "live view" on the rear LCD, making it easier to compose photos underwater.
On Four Thirds system DSLRs like the Olympus E-510 tested in this issue, a 300mm focal length lens becomes the equivalent of 600mm. If you have a teleconverter take that along as well - a 1.

Hands on with the micro four thirds G2 camera from Panasonic
With the G1, Panasonic introduced a whole new genre of cameras. The G2, introduced back in March is basically a straight update of that camera.
One such example is the Four Thirds system supported by Olympus, Kodak and Fujifilm. However, a proposed standard will only obtain the required traction when most of the major digital camera manufacturers join it.
Place the eye in one of the four thirds of the frame
We use the rule of thirds for composition all the time. Why not use it to emphasize the eyes and draw more attention to them? Have another look at the two example photos.
*Notable Exceptions: The "Micro Four Thirds" or 4/3 standard has interchangeable lenses, but doesn't use the standard SLR viewfinder mechanism (Olympus/Panasonic cameras).

Finally, and this isn't strictly to do with manual focus lenses per se, but you can't use Minolta Vectis or Four Thirds (Olympus, Kodak, Fuji, Sanyo, Sigma, Panasonic and Leica) lenses on EOS cameras.
Such lenses are designed to generate image circles to cover APS-C or "Four Thirds" sensors which both are smaller than 35mm film frames. This allows these lenses to be much smaller and cheaper to manufacture.
Panasonic has launched the Panasonic Lumix DMC-G3 - the latest model in their Four Thirds line-up. Rosie Tanner attended the launch in London and had a chance to really get to grips with the new lightweight model.
Canon and Nikon offer 1.6x and 1.5x bodies respectively, while Olympus and other members of the four thirds group offer 2x bodies.
