Overview

The S10 24-72 mm lens has a 3.0x optical zoom lens with coverage from 24 mm wide-angle to 72 mm medium telephoto. So it can be a wide-angle lens convenient for both expansive landscapes and narrow indoor spaces, a standard lens providing a natural visual field with an angle of view close to that of the naked eye, and a medium telephoto lens, a type that is frequently used for portraits and that provides a view similar to the eye when concentrating on a single point. With this wide focal length coverage in a single lens, it is possible to handle a diverse range of subjects. The photographer can enjoy visual effects unique to photography, such as using the wide-angle capability to get close to the subject and emphasize perspective.

The lens configuration has 7 groups and 11 elements, and the rear focus technique convenient for fast AF is used. Including the first element, a large-diameter aspherical lens, there are a total of 4 aspherical lens elements situated in optimum positions. Using special low-dispersion glass and other techniques, we have achieved compact size while suppressing image distortion and colour fringing near the edge, even at 24 mm wide-angle. High-resolution and contrast are achieved 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 delivered to the photographer.

Close-up photography with a minimum shooting distance of 1 cm (wide-angle; distance from front of lens). In addition, with zoom macro, which provides greater magnification than standard macro, it is possible to fill the frame with a 17×132 mm subject or a 4.3×3.2 mm subject if digital zoom is also used.

As it is intended to be used as the photographer's "everyday" zoom lens, the S10 utilizes a 1/1.7-inch high-sensitivity image sensor to achieve both high-level image quality and superior portability. Featuring both high-sensitivity and low-noise characteristics, this CCD can handle the wide sensitivity setting range of ISO100 to 3200. Even in high-sensitivity photography, it is possible to obtain natural-looking images with tonal gradations.

Vibration Correction function developed independently by Ricoh, 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, and when shooting nightscapes beyond flash range. In addition, blurring from both camera shake and subject movement can be suppressed using the high-sensitivity shooting capability of up to ISO3200.

1  The picture quality modes which can be set vary depending on the image size.
2  A JPEG file is also recorded (the JPEG file may be a FINE- or NORMAL-quality file with the same dimensions as the RAW file or a VGA file 640 × 480 pixels in size). RAW files use the standard DNG format promoted by Adobe Systems Incorporated.
3  For reference only; actual number of shots varies greatly according to how camera is used. We recommend that you carry spare batteries when in use for extended periods. (Shooting capacity was measured using CIPA-standard parameters. These are only estimates; performance may vary                        depending  on usage conditions.)
