The Olympus E-3 was until 2011 Olympus Corporation's previous flagship camera, positioned as a professional DSLR camera. It is the successor to the Olympus E-1, which was launched in November 2003. The E-3, originally codenamed Olympus E-P1, was announced on 17 October 2007. The E-3, like the other...

Features

The E-5 has a live preview full articulating screen
Articulating screen
In digital photography, an articulating screen is an LCD which is on a pivot, allowing it to swivel. Articulating screens can be useful in many circumstances; for instance, if one wanted to take a picture of themselves while holding the camera at arm's length, they could flip out the LCD and...

, contrast-detect autofocus in live view mode, and the ability to control up to three wireless flash groups without external transmitters. The camera is also fully weatherproof even with the popup flash in the "up" position when used with weatherproofed lenses such as the Zuiko Digital "High Grade" and "Super High Grade" lines. Like many recent DSLR's, it can record video; the E-5 supports resolutions up to 720p. It is very similar to the E-3 that preceded it in operation and design.

Additional features include:
  • Fast autofocus (Olympus claims that this was the world's fastest autofocus at the time the camera was released (when used with the Zuiko Digital ED 12–60mm 1:2.8–4 SWD

  • 100% viewfinder with ×1.15 magnification with a 50 mm lens (as 25 mm is the "standard" lens on the 4/3 format, this is equivalent to ×0.57 in 35 mm format)
  • External white balance sensor

    Image stabilization is a family of techniques used to reduce blurring associated with the motion of a camera during exposure. Specifically, it compensates for pan and tilt of a camera or other imaging device. It is used in image-stabilized binoculars, still and video cameras, and astronomical...

    Dust reduction system
    A dust reduction system, or dust removal system, is a technology employed by several manufacturers of digital system cameras to solve the problem of dust particles adhering to the image sensor. Some systems remove or clean the sensor by vibrating at a very high frequency—between 100hertz and...

The camera is compatible with existing BLM-1 batteries used in the E-1, E-3, E-300, E-330, E-500 and E-510.

Recent iterations of Olympus DSLR's (including the E-420, E-520, E-620, E-30, and E-3) have used a relatively strong antialias filter. This has the effect of eliminating moire and aliasing artifacts, but reduces the camera's ability to capture very fine detail when used with very sharp lenses. In the E-5, Olympus has chosen to use a much weaker antialias filter along with a new software demosaicing/sharpening algorithm that is claimed to preserve fine detail while eliminating moire. In principle this approach allows the E-5 to capture more fine detail than cameras with similar resolution (when used with sufficiently sharp lenses).

Along with other Olympus 4/3rds bodies, the E-5 has a on-demand pixel mapping, a dust reduction system, vignetting
Vignetting
In photography and optics, vignetting  is a reduction of an image's brightness or saturation at the periphery compared to the image center. The word vignette, from the same root as vine, originally referred to a decorative border in a book. Later, the word came to be used for a photographic...
