The GR LENS A12 50 mm uses a 23.6 mm × 15.7 mm CMOS sensor and 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.

RICOH LENS S10 24-72 mm can do 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.

A 1/1.7-inch high-sensitivity image sensor is used 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.

Digiscoping with the S10
Currently, the S10 is the most useful lens unit for digiscoping, depending on your scope model, with the lens at it's widest angle, vignetting will be apparent, but after applying some optical zoom (approx 2.5 with the Olivon T-84) vignetting can be completely eliminated.

The lens unit also gives you the option of adding a clip on filter thread adapter allowing for stepping rings and filters to be attached at the end of the lens. This gives the you option of attaching the camera to DSLR digiscoping camera brackets for a more solid connection.
