Conventional view camera lenses are not very well suited for use with the new area CCD capture backs. The focal lengths of view camera lenses you already have become too long for studio use. What would be a normal lens on a 4x5 becomes the equivalent of over 500mm when used on a 3x3 cm CCD.
The Sinaron-Digital lenses have been designed for use with area CCD backs on Sinar view cameras. They have shorter focal lengths which are appropriate to the smaller size of the CCD chips relative to 4x5 film.
Digital Lenses also feature increased resolution to get the most out of the high pixel density of area CCDs. The MTF curves below help illustrate the resolving power of digital lenses compared to their 4x5 equivalents.
The lenses are mounted behind the front standard, which moves the lens and CCD as close together as possible while still maintaining a comfortable separation between the standards. This permits greater swings and tilts than traditional view camera lenses.
Digital lenses are supplied in special DB mounts. They can only be used with the Sinarcam or Expolux shutter system.
