Cambo Wide-RS 19mm Nikon Lenspanel / Electronic Aperture ( WRE-2019 )
We made the optical parts from Nikon's PC-19 available for use on Cambo WRS and Phase One XT technical cameras. The lens has been rehoused and fitted with a controller for the electronical aperture. The image circle is large enough to cover the sensor of an IQ3/IQ4 back and still permits about 4mm of shift. Edge-to-edge sharpness is excellent.
Since the lens has no leaf shutter, one has to rely on the On-Sensor shutter as used in digital backs like Phase One IQ3/IQ4 and the Hasselblad CFV-II 50c.
