Selling this back as I rarely need big multishot files anymore, and have upgraded to a eMotion 75LV.
This back shoots tethered only and can shoot in 1, 4, or 16 shot mode. In 16 shot mode with an electronically controlled vibration free shutter like the Rollei or Schneider view camera shutters it can produce 88 megapixel files, 489MB in size (16 bit) These files are over 10,000 pixels wide on the long edge. In 4 shot mode the files are the same physical size as one shot mode (22mpx, 122MB 16-bit) but there is no color interpolation, hence 'true' color, and no chance of moiré. The software is Eyelike Capture pro and works with the latest version of OS X, 10.5.6. I have used it on both Intel and older Macs. The RAW files can then be opened in Sinar eXposure software and converted to DNGs if need be. Has a 10 metre firewire cable and adapters, foil stack spacers, winder cables and trigger cables for both a Contax 645 and a Hasselblad V (a common 'generic' mount for sliding backs on view cameras).
