Blue Ring Lenses: Compatibility with Phase One XT and Cambo WRS/WRC

 In Cambo, News, Phase One, Tech Camera

Cambo has now released a standard version of the Phase One Blue Ring Lens Adapter for the Cambo WRS/WRC and Phase One XT Cameras.

This combination will work with digital backs that have a built-in shutter (sensor activated electronic shutter), which work as shutterless digital back, such as the PhaseOne IQ3-100 and the IQ-4 series.

The aperture of the older Mamiya lenses can be set manually, the shutter (if applicable) needs to stay open.

The practical use of lenses may be limited to those that have enough image circle coverage for the used digital back when using shifts.

The use of the later lenses of the DF and XF system is mechanically possible, but there is no communication between the lens and the camera body. This means that electronically set apertures can NOT be controlled and must be set on a Phase One DF/DF+/XF camera body.

In addition to the Blue Ring lenses, below you can find the listing of most Cambo lens panels that are suitable to work on the Phase One XT:

WRA-2035 with Rodenstock 35HR in Aperture Only mount.
WRA-2040 with Rodenstock 40HR in Aperture Only mount.
WRA-2050 with Rodenstock 50HR in Aperture Only mount.
WRA-5105 with Rodenstock 105HR-Macro in Aperture Only mount.
WRA-2138 with Rodenstock 138HR-Float in Aperture Only mount.
 
WTSA-832 with Rodenstock 32HR in Aperture Only mount in Tilt/Swing panel version.
WTSA-835 with Rodenstock 35HR in Aperture Only mount in Tilt/Swing panel version.
WTSA-840 with Rodenstock 40HR in Aperture Only mount in Tilt/Swing panel version.
WTSA-850 with Rodenstock 50HR in Aperture Only mount in Tilt/Swing panel version.
WTSA-870 with Rodenstock 70HR in Aperture Only mount in Tilt/Swing panel version.
WTSA-892X with Rodenstock 90HR in Aperture Only mount in Tilt/Swing panel version.
 
WRE-CA for use with Canon lenses such as T/S lenses with larger image circle.
WRS-HV for use with Hasselblad-V lenses.
WRS-M645 for use with Mamiya-645 lenses.
 

All above lenses have no electronic connection to the XT body and have no transfer of data for aperture setting or exif-data. These lens panel also have no shutters and should be used with the sensor based electronic [rolling] shutter of the IQ3 100/IQ4 100/150 models.

Expected to begin shipping by the end of January 2020, the Cambo M645 Adapter sells for $675 and can be ordered immediately.
