, the Leaf DCB1, nicknamed ‘The Brick’, which had a resolution of 4 million pixels (4 megapixels). As of January 2011, Leaf produces the Aptus line of digital camera backs, ranging from 22 to 80 megapixels. Until 2010, Leaf also produced photography workflow software.

Digital Camera Backs

After Leaf's DCB, the digital backs evolved into two product lines, the Aptus and the (now discontinued) Valeo. The main difference is that the Aptus models have a 3.5" touchscreen

 packs for both the Aptus and the Valeo, otherwise the back must be powered via a Firewire connection to a computer. The Valeo models need a Leaf Digital Magazine as well for untethered use, where the Aptus models have a Compact Flash slot.

Current Models

Aptus II models are very similar to corresponding previous Aptus models, with the notable differences:
  • Live view available with Phase One 645AF and 645DF bodies (+ Mamiya AFD III & DF), no dongle required. Live view is available on Capture One with large format bodies for legacy Aptus 22 and up, Live View dongle is no longer required.
  • Camera controls (aperture, shutter speed and shutter release) on Phase One 645AF and 645DF bodies (+ Mamiya AFD III & DF)
  • Faster shooting speed, shot-to-shot and faster transmission to tethered computer
  • Firewire 800 connection replaces Firewire 400
  • Slightly different color response


The following table shows the models which Leaf still shows on their website as current models.

It is impossible to convert the mount of a digital back for a different medium format body via adapter or conversion plates, because the sensor would then not sit within the film plane
