• As a further refinement of the D500 model, the D600 yields smarter, cooler images of an orchestra conductor wearing a tailcoat. • The built-in design power of the D600 directs a number of functions just as a conductor directs the players in an orchestra. • A sliding mechanism was realized through an interminable trial-and-error process to produce smoothness and exercise moderation, and a variety of engineering technologies were applied to reduce the weight (by applying engineering plastics, for instance). • Black in combination with metallic gray represents an excellent tone, yielding images that are homogeneous with the design. • Cutting-edge functions were integrated into the model, including a 2.0-inch LCD screen, 2-megapixel camera, and dual stereo speaker.
