Perhaps you have heard of, maybe even seen a new Olympus PEN or P-E1, the retro stylized pocket-sized camera. It has graced the cover of Shutterbug magazine and made Internet headlines. If you are really into the latest and greatest camera gear you might be familiar with the Panasonic DMC-GH1, another pint-sized powerhouse. What do these two cameras have in common? They share the same format: Micro Four Thirds.

Micro Four Thirds is the little sister to the Four Thirds open standard for camera and lens construction introduced in 2002. Micro Four Thirds cameras are designed to use Live View (LCD displays) exclusively. No mirror box, no optical viewfinder. The result is an interchangeable lens camera with an 18 x 13.5mm MOS sensor and half the flange back distance (the distance from the lens mount to the senor) of a traditional DSLR. That translates into a camera body that is 4.8″w x 3.5″h x 1.8″d and weighing less than a pound.
With half the focal distance for a given angle of view compared to a DSLR, a Micro Four Thirds lens has twice the reach of 35mm lenses. In simpler terms, a 25mm Micro Four Thirds lens is equivalent to a 50mm 35mm lens, a 100mm equivalent to a 200mm, so on and so forth. The advantage is obvious – significantly smaller lenses (i.e., 6mm smaller in diameter than a Four Thirds lens). In addition to size and focal length advantages, a Micro Four Third lens has eleven contact points that translate all the data needed to use Live View, reduce lag time, and increase communication speed between the lens and camera body.

The secret behind all this spy-sized gadgetry is Live View. Live View makes use of LCD displays, 480,000 pixels of them. All of the cameras have good sized LCDs (3″+/-) on the back, a couple have built in Electronic View Finders (EVF), while others have detachable EVF’s. Using the LCD on the back of the camera to compose a photograph is just like using a point and shoot. Using the EVF is like shooting with a video camera. All the camera info is displayed on the screen with Live View.
The MFT cameras by design offer the exposure control features of a DSLR: full manual, aperture or shutter priority and (of course) for the novice or just lazy, an auto pilot mode. All the lenses are auto focus using high-end 24-point systems. Some models have image stabilization built into the camera others have stabilization in the lens. Either way the systems work exceptionally well.
The talk on the street is not only about the teeny tiny camera bodies and the mini lenses; the fuss is over the image quality. The Micro Four Thirds cameras with their 12 point-something megapixel MOS sensors can capture up to a 22mb RAW+fine file. Image quality – in test after test – rivals some of the most praised DSLR’s. JPEG images are a no-brainer for these mighty tikes. They’ll even do RAW + JPEG.
How about format ratios? How about four format ratios! 4:3, 3:2, 16:9 and 6:6!
All the available Micro Four Thirds cameras on the market have an ISO range from 100-3200; unfortunately none of them handle the higher speeds very well and noise occurs at 800+. That’s why they have a hot shoe and/or a pop-up flash. [Editor's note: The Olympus P-E2 which began shipping at the end of 2009 (approximately $1100 at BHphoto) has improved capabilities up to 6400 ISO (manual), and reduced noise.]
No jury is out on the image quality of the Micro Four Thirds system camera but stills are just the tip of the iceberg. Full HD 1920 x 1080p video is a nice little feature. At the moment only the Panasonic DMC-GH1 [approximately $1200 at BHphoto] offers this resolution, most of the others only have 1280 x 720 – which is more than good enough. Stereo sound? No problem! External microphone? Got that. In camera editing? Child’s play! Go ahead, mix in a sound track and you’re on your way to Sundance.
The one bummer about Micro Four Thirds is that there are only two players in the game, right now: Olympus and Panasonic. The good news is they have produced some awesome cameras, although only six models (three from each manufacturer) are available. Prices range from $500 – $1500 and include a lens, and sometimes a choice of lenses. Panasonic even has one model in three color options: black, blue, or red. Samsung has very recently introduced their own version of a Micro Four Thirds-like camera, and while it does not follow the open format parameters the features and performance seem to be equal.
My take on Micro Four Thirds? I think I might get one rather than another DSLR body. My advice is to check them out – go to your favorite camera store, ask to see all the models available, spend forty-five minutes with the sales associate while asking a ton of questions, and then say, “Oh, I’m just looking.” That never happens in camera stores.
Seriously, this format could be a game changer.
Would love to hear comments, thoughts, perhaps one of our readers is lucky enough to own a MFT and would be willing to share a photo or two.
