Ricoh interchangeable lens module S10 GXR — 5.1–15.3 mm focal, F2.5–4.4, 11 elements/7 groups, 161 g

Ricoh interchangeable lens module S10 GXR offers a 5.1–15.3 mm focal range with an aperture range of F2.5–4.4 and an optical construction of 11 elements in 7 groups. Designed for use with Ricoh GXR camera bodies, the compact module weighs 161 g and measures approximately 68.7 × 57.9 × 38.6 mm. The lens covers wide-angle to short-tele perspectives, making it suitable for landscape, travel and everyday photography where portability and versatile framing are required.

Advantages

The module combines a broad focal length coverage and a relatively fast aperture range for a small, lightweight optical unit. Its optical design with multiple lens elements aims to reduce distortion and chromatic aberration across the focal range, while the compact dimensions and low weight support handheld use and easy transport. The module’s construction allows close-focusing at short distances and integration with Ricoh GXR bodies for reliable mechanical and optical alignment.

Suitable for

• Landscape and wide-angle scenes
• Travel and street photography
• Everyday snapshots and environmental portraits
• Close-up compositions at short subject distances

How to use

Attach the module to a compatible Ricoh GXR body using the system’s mounting interface until it locks into place. Set the camera to the desired shooting mode and adjust focal length by rotating the zoom control to frame the subject. Use the available aperture range to control depth of field and exposure; when shooting in low light, select a wider aperture and increase ISO as needed within the camera’s limits. For close-up shots, move the camera close to the subject while confirming focus through the viewfinder or live view.

Usage recommendations

For optimal sharpness across the frame, ensure the lens module is properly seated on the GXR body and perform periodic alignment checks if you notice edge softness. Use a steady hand or camera support for longer exposures, and pair the module with compatible accessories (such as protective caps or conversion attachments specifically designed for the GXR system) to expand wide-angle or telephoto capability where supported.
