The Micro Four Thirds camera market is starting to get a little bit crowded: at the time of writing, both Panasonic and Olympus have three models available, with more touted to come this year.
The Lumix GF1 is the most successful of these cameras so far in terms of delivering on its promise of SLR-like images in a compact form factor. Though it is expensive, it's a worthwhile investment for any photographer serious about entering the Micro Four Thirds world.
Design and features
Sharing a similar retro aesthetic to the other popular Panasonic camera, the Lumix LX3, the GF1 is a compact version of the company's other Micro Four Thirds cameras, the G1 and GH1. The body is heavier than it appears, at 285g without a lens attached.
Having used the, and the extensively, the GF1's controls are well placed on the smaller form factor, though the video record button has been moved to the top of the camera, alongside the shutter button and mode dial. As on the other models, switching between aperture and shutter speed selections is done by pressing the control wheel which is a little disorienting if you are not accustomed to it, but works well once acclimatised. Unlike its older G-series companions, the GF1 has no articulating LCD screen. Instead, it's just a 3-inch screen at the back of the camera.
At the top around the mode dial is the standard G-series method of changing the shooting mode, from single, continuous, bracketing and self-timer. The flash has its own dedicated button which pops it up from the main body; note that even in automatic mode the GF1 will not automatically activate the flash. Like the other cameras, the GF1 allows you to preview changes to shutter and aperture in real time, though actually getting a clear representation of the final picture is tricky thanks to the refresh rate of the screen.
The GF1's main competitor is the(the isn't really in the same ballpark when it comes to price and specs). Side by side, the two cameras share a lot of things in common but the main differentiating factor is the GF1's pop-up flash and slightly higher resolution LCD screen. Below is a table comparing the two cameras on their main selling points.

Surprisingly, Panasonic has not chosen to bundle the GF1 with an electronic viewfinder (EVF), like the E-P2, so we were unable to test the EVF, and from specifications alone the Olympus version trumps it on resolution. The GF1 also lacks a dedicated microphone input for an external mic; the E-P2's accessory port allows for a stereo microphone to be attached.
The provided pancake 20mm f/1.7 lens is incredibly light and fits nicely on the body of the GF1. However, there is no image stabilisation built into the lens, nor is there image stabilisation in the body of the camera which may be a sore point for some photographers wishing to mount older, classic lenses on the GF1. The 20mm has a nice feel to it though, and allows for easy manual focus thanks to the magnification screen that appears on the LCD whenever the focusing ring is turned.

Video encoding is taken care of thanks to AVCHD Lite or motion JPEG, 60 frames per second at 720p. Like the E-P2, the GF1 can record video with filters such as film mode (including black and white or the natural/vibrant/nostalgic effects).
Other features that may be of interest include various scene modes including Peripheral Defocus which alters the focus and widens the aperture automatically in order to blur the background (essentially the same as going into aperture priority mode and adjusting the aperture yourself).
Strangely, the GF1 produces better images using the peripheral defocus mode rather than dialling in the same exposure in aperture priority or manual mode. The peripheral defocus image (top) looks clearer and has better colours than the same exposure on aperture priority mode (bottom) at f/1.8, 1/2000s. (Credit: Alexandra Savvides/CNET Australia)
The GF1 certainly is on its toes when it comes to performance, especially compared to the Olympus Pen cameras. Starting up and taking its first shot within 0.8 second, the Panasonic was much faster than the E-P2 which we clocked at three seconds.
