The problem:
While manual focusing certainly represents an important alternative for photographers in obtaining sharp shots, many photographers choose to use the camera’s autofocus (AF) to get their images in proper focus. The sheer convenience it affords is a winning argument. However, not all AF systems manage this task equally well.
The most vital prerequisites an AF system must fulfil are that of precision and speed. And it must handle this task reliably – even in difficult situations such as low light, little contrast or vertical line patterns. This issue is of particular importance for professional photo - graphers who rely on results of consistently high quality to ensure they maintain their reputation just as their livelihood.

An analysis of around 1000 photos shot by professional photographers showed the distribution of the main focal point of these compositions. Using this information, the eleven AF points in the Olympus E-3 cover all of these areas. |

The solution:
With the introduction of the Olympus E-3 D-SLR, a newly-developed AF system was presented that set new standards in terms of speed, precision and reliability. Together
with the ZUIKO DIGITAL ED 12-60mm SWD lens, the world’s fastest AF speeds in a D-SLR could be achieved with the highest levels of precision. Besides blisteringly-fast AF performance, photographers also benefit from a system that functions reliably across the whole gamut of photo situations including subject tracking.
How it works:
Hound’s tooth sensor layout A half pitch-shifted dual sensing array detects focal points more accurately than ordinal types. It combines each output from the sensing array to obtain exceptionally sharp output.
Photographers have the choice to precisely set the active target area and also choose from various target-selection cycles.
