From the Manufacturer:
The next era in Micro Four Thirds technology is about to begin. The revolutionary mirrorless camera, the OM-D E-M5, has an exceptionally light and compact body. Its Electronic View Finder enables photographers to check exposure levels, white balance and preview Art Filter effects in real-time. When shooting, the photographer can instantly create a truly unique world and preserve it in exceptional quality. The world will be transformed from something you see to something you take part in.
The OM-D is a groundbreaking digital interchangeable lens camera, perfect for people who want to take part, create, and share.
Intuitively Designed Electronic Viewfinder
The OM-D's electronic viewfinder (EVF), with 120 fps refresh rate, features a high-resolution 1.44-million dot LCD, 100% field-of-view coverage, and 1.15x maximum magnification that lets you totally immerse yourself in your subject, and actively control image creation. The EVF also enables you to enlarge the focus point for precision focusing in virtually any shooting situation, and can show you the effect of Highlight & Shadow Control, White Balance, Exposure Compensation, Aspect Ratio, and a host of other settings and advanced digital image processing functions right in the viewfinder. With improved precision and responsiveness that make it as easy to use as an optical viewfinder, the E-M5's advanced EVF gives you virtually unlimited creative control. Eye sensor technology automatically activates the EVF when you bring the camera to eye level.
Dust Proof, Splash Proof
Trouble-free shooting in all environments is assured by our proven dust-proof and splash-proof technology. Multiple ring-shaped seals protect the camera from sand, dust, rain, and water spray, making it ideal for all kinds of outdoor shooting. What's more, the OM-D extends this protection to the bundled attachable flash unit as well.
Two full size control dials in concert with dedicated function buttons allow fast setting changes on the fly. Adjust highlight and shadow, exposure, white balance, aspect ratio and more and preview the results instantly in the EVF or on the tilting 3 in. OLED touch screen.
Lenses and Accessories
The OM-D is supported by an ever-expanding range of wide-angle, macro, portrait, and telephoto Micro Four Thirds M.ZUIKO DIGITAL lenses. System accessories include cases, straps, filters, external flash units, and mount adapters for Four Thirds System lenses and OM System lenses.
High Power Sensor
A 16-megapixel Live MOS image sensor for rich tonal expression, increased dynamic range and support for a maximum 25,600 maximum ISO.
M.ZUIKO Digital Lenses
A wide line-up of Micro Four Thirds lenses featuring the most advanced optical designs and performance take full advantage of the sensor’s capabilities.
The TruePic VI image processor delivers superb color fidelity and the fast performance required for continuous still shooting and movie capture. The optimal balance of these three factors ensures the high resolution, sensitivity, and color accuracy you need to brilliantly capture the world around you.
5-Axis Image Stabilization
The E-M5 is equipped with the world's first 5-axis image stabilization system, and can compensate for vertical, horizontal, and rotational camera shake that conventional 2-axis systems of the past have been unable to handle. Built into the camera body to ensure effective stabilization with all lenses, its unique 5-axis design makes it particularly effective when taking high-magnification telephoto shots, macro close-ups, and long exposures. In addition, it can be activated by pressing the shutter button halfway, so you can also use it to stabilize the viewfinder image and obtain a crisp, clear view of your subject that makes it easy to frame and compose your shots.
FAST AF has been made even faster and more accurate on the E-M5. Improved new 3D Tracking AF assures you won't miss the moment even when subjects move toward or away from you, and the high-sensitivity image sensor ensures superior AF performance even in dim light.
9 FPS High-Speed Sequential Shooting
Thanks to the 16-megapixel Live MOS image sensor's high-speed read-out performance, the E-M5 offers maximum sequential shooting at 9 fps, making it easy to capture sports action or fast-moving subjects such as pets, kids and wildlife. In addition, a compact high-speed shutter mechanism enables the E-M5 to offer this performance without compromising the handling advantages of a light and compact body.
Face and Eye Detection AF
Improved Eye detection lets you choose from left or right eye priority modes to get the correct focus point quickly for perfect portraits every time. Up to 8 separate faces can be detected by the AF system.
3D AF Tracking
Advanced "predictive" AF system can track moving subjects moving not only on the x and y axis but along the z-axis as well. The system uses face, color, and pattern information and can support 4.2 fps continuous frame rates.
Tilting 3 in. OLED Touchscreen
In addition to offering dial and button controls, the E-M5 is the first Olympus camera to feature a tilting touchscreen monitor for intuitive fingertip operation. The 3-inch OLED touchscreen delivers high-resolution images of your subject with rich color reproduction. It also responds instantly to your touch with fast operation that makes it easy to focus on subjects, play back images, and adjust settings such as exposure and white balance.
In-Camera Art Filters
11 Art Filters that can be applied to both still photos and HD movies right in the camera. Apply these filters instantly while shooting or apply post capture. Combine Art Filter effects for custom variations. Apply frames for even more creative control.
Unleash your imagination by combining JPEG frames with overlay preview to produce your own unique vision. Additional RAW frames can be overlaid in the playback edit mode for nearly unlimited possibilities.
Choose from 5 different Aspect ratios while shooting to get the special compositional effect your photo deserves traditional 4:3 and 3:2, 16:9 for cinematic effect or 6:6 that emulates the medium format look.
