The Olympus OM-D E-M1 uses the Micro Four Thirds lens mount system for its interchangeable lenses. Olympus shares this system with Panasonic, allowing for a greater range of lenses to be used by both companies. The E-M1 can also use the MMF-3 Adapter that allows you to use all of Olympus's OM lenses. This adapter has the same sealed construction as the camera and the M.Zuiko 12-40mm PRO lens.
Capturing the images for the E-M1 is a 16-Megapixel 4/3 Live MOS imaging sensor. This RGB sensor features Supersonic Wave Filter technology to keep the sensor clean and dust free. With its built-in Phase Detection pixels, the camera is capable of extremely fast Autofocus from its Hybrid system. This system combines the Phase Detection with the standard Contrast Detection that you find on point-n-shoot digital cameras. The combination results in not only fast but incredibly accurate autofocus.
Working along with the sensor in Olympus's new TruePic VII processor. This newly designed and more powerful processor increases the camera's operation speeds and capabilities along with improving its overall image quality and noise reduction.
The strong and lightweight Magnesium Alloy construction of the E-M1 keeps the camera as light as possible while still providing all the necessary strength and ruggedness. This body has been designed to take a few bumps while providing protection to the components within.
Our sample E-M1 camera also came their new M. Zuiko Digital ED 12-40mm f2.8 PRO lens. This Pro grade lens has a 35mm equivalent of 24-80mm (3.3x optical zoom) and a maximum aperture of f2.8 throughout the zoom range. It was designed to be as tough as the E-M1, featuring the same splashproof, dustproof and freezeproof construction as the camera. This lens combined with the camera's amazing 5-axis optical image stabilization system, providing up to 4 stops of correction, gives you unparalleled low-light performance from an ILC.
Instead of a switch on the 12-40mm lens, the lens ring itself slides back and forth to switch between auto focus and manual focus. This allows for faster and easier switching between the two modes while shooting. Manual focus is very easy with the E-M1 as well thanks to features like peaking and manual focus zoom assistance.
Shown above is the camera's hot shoe and accessory port. The included flash unit uses both in order to take advantage of the camera's exposure information. This combination also works with other external flash units as well as an external microphone and macro arm light. When not in use, there are two covers that keep the port and hot shoe dry and dust-free.
Included with the E-M1 is this detachable flash unit. When the unit is on the camera, it can fold up and down to help keep it out of the way when not in use. This compact unit is not much bigger than what is found on most compact cameras, featuring a GN of 10(meters) at ISO 200 and a top sync speed of up to 1/320 of a second.
The E-M1 also has wireless flash control capabilities, allowing you to control 4 groups over 4 channels. It is compatible with the FL-50R, FL-36R, FL-300R and FL-600R external flash units as well as the Olympus Wireless RC Flash system.
Viewing and framing your images can be accomplished with the incredibly high resolution 3.0-inch, 1037k dot tiltable touch LCD screen. The electrostatic capacitive touch LCD has a total tiltable range of 130°; 80° up and 50° down. The touch features allow for a wide variety of features including WiFi, touch shutter and touch super control panel. 7 levels of both brightness and color temperature control allows you to see the adjust the screen for any situation.
If you prefer an eye-level viewfinder to shooting with the LCD screen, then you will love the high-definition EVF with the equivalent of more than 2.3-million dots. With 1.48x magnification and a full 100% field of view, this blows away any optical viewfinder. It also provides you with all of the information that is shown on the LCD screen, real-time viewing and electronic level displays. Its diopter adjustment range is approx. 21mm (-1m-1, Distance from rear lens surface) / -4 ~ +2m-1.
Around the EVF you can see the shooting view and AEL/AFL lock buttons.
During the E-M1 unveiling event in NYC, Olympus displayed the E-M1 with the 12-40mm lens resting inside of a large ice sculpture to promote is toughness and all around durability.
