As of 2012, Leaf produces the Credo line of digital camera backs, ranging from 40 to 80 megapixels.

After Leaf's DCB, the digital backs evolved into two product lines, the Aptus and the (now discontinued) Valeo.

For untethered usage, you will need battery packs for both the Aptus and the Valeo, otherwise the back must be powered via a FireWire connection to a computer.

[2][3][4] (f-stops) The Aptus-II models are equipped with a specific mount to fit one of the following camera systems: 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 (since the sensor needs to sit the same distance from the lens that the film would).

Such conversion may be possible by sending the back to Leaf to be physically reconfigured, depending on the specific model.

The AFI backs (in the Discontinued Models) are specifically designed to work with Sinar and Rollei systems.

Note: From v11.2.9 on only supports Aptus models [6] Used together, allows browsing of your "Shots" folder on wireless devices (iPad, iPod Touch and iPhone).
