With wide focal length coverage in a single lens, the 24-72 mm 3x optical zoom
can handle a diverse range of subjects. The lens configuration has 7 groups and 11
elements, and the rear focus technique convenient for fast AF is used.
Beginning with a large-diameter aspherical lens as the first element, there are a
total of four aspherical lens elements situated in optimum positions. Using special
low-dispersion glass and other techniques, we have achieved suppressing image
distortion and color fringing near the edge, even at 24 mm wide-angle. With an
extravagant optical design, compact size is maintained while achieving high-
resolution and contrast at all focal lengths. In production, the lens group optical
axis and image sensor gradient are precisely adjusted in micron units. Superior
optical performance to the edge of the image is insured before the image is deliv-
ered to the photographer.
Close-up photography with a minimum shooting distance of 1 cm (wide-angle;
distance from front of lens) is possible. When used in combination with the digital
zoom, which provides greater magnification than standard shooting, it is possible
to fill the frame with a subject of about 4.4×3.3 mm size.
Because it can achieve both high image quality and the portability needed for a
photographer's "everyday" zoom lens, a 1/1.7-inch CCD is used as image sensor.
Providing both high-sensitivity and low-noise, this CCD can handle the wide sensi-
tivity setting range of ISO100 to 3200. Even when shooting at high ISO sensitivity,
it is possible to obtain natural high-quality images with low levels of both color
noise and luminance noise.
RICOH LENS S10 24-72 mm uses the Vibration Correction function developed
independently by Ricoh. It is effective for preventing the camera shake that can
occur in various situations, such as when you want an ambient-light atmosphere
for sunset or party scenes, when shooting in museums and other public facilities
where flash use is prohibited, when shooting nightscapes beyond flash range, and
when shooting dark scenes with medium telephoto. In addition, blurring from both
camera shake and subject movement can be suppressed using Auto-Hi (high sensi-
tivity auto), which can be set as high as ISO3200.
