Focal Length: The focal length (f-value) is the distance, in mm, from the centre of the lens to the focal point where the image is produced. Raising the f value magnifies the subject and shrinks the field of view (telescopic), while lowering the value shrinks the subject and enlarges the field of view (wide). The field of view also varies depending on the size of the film or CCD.
Optical Zoom: Optical zoom allows you to capture a more telescopic or wide-angle setting. As its function is optical, image quality is not affected even when the magnification is increased.
Precision Digital Zoom: The Precision Digital Zoom function enlarges photos while leaving details faithfully intact by applying sophisticated image compensation based on Sony’s proprietary SRC signal processing technology. This function can double the image size regardless of the image’s original size. It delivers less image deterioration than conventional digital zoom, and smoother continuous digital zooming is possible all the way from wide-angle to telephoto.
Exposure: The total amount of light allowed to fall on the image sensor during the process of taking a photograph. It is a combination of the length of time (camera shutter speed) and the level of illumination (lens aperture) received by the image sensor.
Dynamic Range Optimiser: Using sophisticated algorithms, the Dynamic Range Optimiser adjusts for favourable exposure and contrast best suited for the environment and the individuals in the picture. When posing against a highly contrasted background, the BIONZ Processor corrects for exposure and contrast levels and allows for better backlight compensation and white colour expression. Facial details and background subtleties are all beautifully captured by the BIONZ Processor.
