Product Description

The Cambo ACTAR-138 Lensplate with Rodenstock HR Digaron-SW Float 138mm f/6.5 Lens is one of the highest-performing lenses available for the Cambo ACTUS View Camera System. Featuring the acclaimed Rodenstock HR Digaron-SW Float 138mm f/6.5, this premium lens is permanently mounted in a dedicated ACTUS lensplate, providing an integrated solution for photographers who demand uncompromising optical performance and precise camera movements.

The HR Digaron-SW Float 138mm incorporates an advanced floating element mechanism that automatically optimizes optical correction throughout the focusing range. Designed for subjects from infinity down to a 1:5 reproduction ratio, the floating optical group minimizes aberrations at every focusing distance while maintaining exceptionally high resolving power close to the diffraction limit. The lens delivers outstanding sharpness across even the largest medium format sensors and extends this performance to the edge of its generous 110mm image circle, allowing extensive shift and tilt movements without compromising image quality.

Engineered specifically for digital capture, the lens effectively suppresses chromatic aberration and keeps geometric distortion below 1%, making it an outstanding choice for architectural photography, artwork reproduction, landscape photography, cultural heritage documentation, and high-end commercial imaging. The recommended working aperture of f/6.5 to f/11 provides peak optical performance, while the manual aperture ring allows adjustment down to f/32 for increased depth of field.

The ACTAR-138 is supplied in a dedicated Cambo ACTUS lensplate, ensuring seamless compatibility with all ACTUS camera models. For photographers using Phase One IQ4 digital backs, Cambo also offers a version equipped with the Phase One X-Shutter, providing fully electronic shutter and aperture control.
