Rodenstock lenses for large format cameras are available in the different shutter versions. Rodenstock can provide lenses in Copal, Compur, Prontor Professional, Prontor Protronic, Horseman ISS, Noble-Prestor and Copal-Press shutters.

The use of neutral grey, vignetting-free Center Filters is recommended for critical motifs and to make best use of image circle of Grandagon-N and Apo-Grandagon wide-angle lenses.

Using large format lenses on cameras without bellows such as shift or panorama cameras requires the use of a focusing facility. The Focus-Mount can be combined with all Rodenstock lenses in shutter size 0.

Aspheric magnifiers are characterised by very fine resolution and high contrast over the full image field and very suitable for preview slides and negatives.

SHUTTERS

An important part of every photographic lens is its shutter. Just as the camera lens is decisive for the optical image quality, the shutter determines the available time range as well as the accuracy of the time set and the aperture values as requirements for correct exposure.

Because the shutter determines the possible uses of the entire photographic equipment, Rodenstock consequently offers a complete range of different shutter types for its high performance objectives:

CENTER FILTERS

For critical shots (e. g. with uniformly coloured areas towards the corners of the picture) the physically inevitable light fall-off can be eliminated by using the neutral grey and vignetting-free Rodenstock Center Filters available for all Apo-Grandagon and Grandagon-N lenses. A Center Filter should always be used if the image circle of a wide angle lens is used right up to the vicinity of the circumference.

Rodenstock center filters are neutral gray concentric graduated filters whose density decreases from the center up to the translucent rim. The fall in density compensates for practically all the light fall-off to the image edge from a working stop of 16. This also produces a uniform illumination. The exposure must be corrected by 1.5 stop. This corresponds to a correction of the exposure time by a factor of 3.

FOCUS-MOUNT

Using large format lenses on cameras without bellows such as shift or panorama cameras requires the use of a focusing facility. The Focus-Mount can be combined with all Rodenstock lenses in shutter size 0. It is possible to install existing lenses at a later date. The Focus-Mount ensures precise focusing and the straight-line connection means that all operating elements of the shutter remain in the same position. The lenses which can be used together with their focusing ranges can be found in the table. More information on applications and adaption can be obtained from your camera manufacturer or from Rodenstock Photo-Optics.
