Da Cine4home:
In order to increase the dynamic range of the W2700, a dynamic diaphragm has been integrated in its light path, which adapts to the image content and thus regulates the luminous flux of the lamp.
The system works well overall and improves the black level significantly, but occasionally caused subtle jumps in brightness in our test scenes. The factor is moderate to avoid over-pumping: The native contrast of the W2700 from 1100: 1 to 1600: 1 (depending on the zoom) is increased to 4000: 1 to 6200: 1 . As an alternative to the dynamic aperture, an adaptive lamp mode can also be used. This works invisibly, but only increases the dynamic range to 2500: 1 to 3800: 1 . A combination of both systems is not possible
Il 2700 w il 5700 hanno diaframma dinamico (meccanico) e il dimming adattativo (lampada che varia di potenza luminosa al variare dell’apl Scene), che possono essere usati in alternativa.
Confermo che su avsforums diversi possessori del 5700 lo hanno mandato in assistenza per diaframma dinamico rumoroso.
