To develop the D4S method for the company, the product developer cooperated with an environmental engineer and applied the principles of multi-criteria decision methods (Cho, 2003) by formulating targets to be achieved, identifying the essential criterion for each target, and then elaborating a criteria ranking system.
We demonstrated that the use of the simple multi-criteria matrix in a form of a star diagram helped to perform D4S by integrating environmental and social aspects during the product design phase in a systematic and transparent way.
The D4S is equipped with the new EXPEED 4 image-processing engine and a new FX-format CMOS sensor, which achieve an effective pixel count of 16.
Launched two years after the Nikon D4, the Nikon D4S may look almost the same from the outside as the D4 but internally there have been many improvements.
Reasons the Nikon D4S was selected for the Best Digital SLR Professional Award
The D4S supports a broad range of standard sensitivities, from ISO 100 to 25600, as well as expansion up to the equivalent of ISO 409600.
Based on the D4, the D4S responds more completely to the demands of professional photographers with revisions to a number of features and functions, including AF performance, image quality, workflow and operation, and movie recording, adopted after running a variety of simulations of the functions required by professional photographers who sometimes find themselves working under quite severe conditions.
In addition to the four time-tested modes available with the D4 (Single-point AF, Dynamic-area AF, 3D-tracking, and Auto-area AF), the D4S offers a fifth AF-area mode known as Group-area AF (uses 5 focus points: one specified by the user, as well as one each above, below, to the left, and to the right of the selected focus point).
As Nikon's new flagship model, the D4S will offer advances over the Nikon D4 digital SLR camera that include even better image quality enabled with adoption of a new image-processing engine, and more advanced autofocusing performance.
The D4S represents a concentration of Nikon's advanced camera development technologies and long experience.
