The Olympus E-P1 combines the casual, easy-to-use persona of a pocket-size point-and-shoot camera with the imaging capabilities of a pro-level DSLR. As an extension of Olympus' proven 4/3 imaging system, the E-P1 can shoot casual stills and video as well as complex imagery with equal ease and precision

.

The Olympus E-P1 enables high-definition capture of still and video images while maintaining full auto-focus functionality and image stabilization with all 4/3-format optics. And unlike video-enabled DSLRs, the Olympus E-P1 maintains full AF in video mode

The E-P1 utilizes the same 12.3-megapixel Live MOS imaging sensor used in Olympus' 4/3-format DSLRs. Measuring 17.3 x 13mm, this sensor is half the size of 'full-frame' DSLR sensors (2x crop factor), but far larger than comparably-sized digital cameras, all of which lack the option of lens interchangeability

Aside from the physically smaller M.Zuiko Digital lenses, the Olympus E-P1 is also compatible with all FourThird-format lenses, which enables you to take advantage of one of the widest angle-of-view (AOV) selections available today (114° to 1.5° AOV, or 14 to 800mm)

.

Live View enables real-time viewing of your still and video images as you compose and capture them

.

The camera's 11-point Imager AF autofocusing system ensures quick and accurate focusing under all lighting conditions. For equally accurate metering, the Olympus E-P1 utilizes a 324-segment ESP metering system. There's also the option of selecting Spot or Center-weighted metering as desired

.

An in-camera stabilization system allows for up to 4-stops EV of movement compensation with all 4/3 and Micro-4/3 format lenses

.

Olympus' Dust Reduction, which runs an ultrasonic cleaning cycle each time you power up the camera, helps keep dust particles out of the image path

.

Advanced shooting modes, including portrait for optimized portrait photography, iAUTO for decision-free shooting under most common shooting conditions, Shadow Adjustment Technology (SAT) for optimizing highlight and shadow details, and Art Filters (Soft Focus, Pale and light Color, Light Tone, Grainy Film, and Pin Hole) are easily employed as needed. Other post-capture editing features include sound dubbing (in stereo) for still and video images

.

You can record video with linear, non-compressed sound, as well as add sound to images post-capture

.

When shooting in Manual Focus mode (MF) a 5x close-up of the center of the image is superimposed into a box at the center of the screen to aid in fine focusing. This magnification can be increased up to 10x magnification
