Cautions

<Caution when replaceing chip (leadless) parts>
• Do not re-use the removed parts, but use new parts. Be careful that the negativ side of the tantalum capacitors are
susceptible to heat.
• Voltage indications are omitted for capacitors other than chemical and tantalum capacitors with a dielectric strength of 50
V or less.All units are uF (p shows pF).
• Chip resistors without indication are 1/10 W.
• KΩ = 1000Ω, MΩ = 1000KΩ
• Variable resistors and semi-variable resistor are abbreviated the specification of B characteristic.

Description of the Main Block Functions

3-3-1. Overview of the new technology

A number of technological innovations have been used on this model. These innovations are described below.
(1) Large-format (15.5 x 23.0 mm) "Super CCD Honeycom SRII" featuring a new structural design
• Ultra-high image quality with a maximum recorded image size of 4256 x 2848 pixels (12.1 megapixels) provided by the
"Honeycom Signal Processing System" and a resolution of 12.34 effective megapixels (high-sensitivity S pixels: 6.17
million; R pixels designed to increase dynamic range: 6.17 million).
• The "Super CCD Honeycom SRII" is a newly designed CCD that increases the dynamic range to roughly 4 times that of
the previous FinePix S2Pro and provides rich and detailed tonal gradations. It provides superb image quality featuring
high sensitivity, a broad dynamic range and a high S-N ratio.
• According to their needs, users can select either "D-Range: Wide" to take full advantage of the extensive dynamic range
or "D-Range: Standard", which uses only the S-pixel signals to form the image and is ideal for continuous or high-speed
shooting.
• When "D-Range: Wide" is selected, the photographer can then choose "AUTO" mode, in which the camera automatically
sets the optimum dynamic range for the scene being shot, or set the dynamic range to "WIDE 1" or "WIDE 2" when the
shot is taken to achieve a particular effect.
• Sensitivity settings equivalent to ISO 100-1600 are available, allowing shots to be taken in wide variety of situations both
in the studio and outdoors.
(2) IEEE1394 and USB 2.0 interfaces allow high-speed transfer of image data to a PC. Also provided is a photography
function that transfers photographed images directly from the camera to a PC via the IEEE1394 interface. (Requires the
optional Hyper Utility HS-V2 version 3.0 software.)
