The WRX-90 Lenspanel is dedicated to the use with IQ4 Digital Backs and has a Rodenstock 5.6/90 HR Digaron-SW lens with Phase One X-Shutter mounted in a helical focussing mount.
This version has a split back focal length, existing of a shorter lensplate and a rear extension unit.
This combination allows for optimised shift without vignetting from the lensbarrel.

The WRX-90 fits to all Cambo Wide cameras with SLW-adapters. The new WRC-490 and 491 require spacers WRC-480 and 481 respectively.
In case the WRX-90 is being used on a XT body, the rear spacer can be replaced with the front spacer WRS-1049.
