For Phase One P45+, P45 and earlier backs. From the Kapture Group web site:
[blockquote]The OneShot Cable Release PHA-001 for view camera and non-Hasselblad medium format application eliminates the need to pre-release or wake-up the PhaseOne digital back. Without the OneShot you have to fire your shutter once and then re-cock the shutter a second time and fire again to capture an image. With the H and P series the second shot must be perform within 4 seconds. When configured as shown the OneShot cable release operates just like a regular cable release eliminating the need to fire your shutter twice.[/blockquote]
I was using with the P45+ back, but it is not needed for the P65+.
This is listed for $395 on the Clumet site:
