Leaf Capture 11.5.2 has been released which includes updates for all Mamiya DM backs to the new Leaf GUI. This new Graphical User Interface allows LCC-in-the-field, hastens boot times, shows 100% views faster, and has an improved interface for use outdoors.
You can download Leaf Capture 11.5.2. Or you can wait for a few weeks for the next release of Capture One which will very likely provide this firmware. If you normally use Capture One 6.3 (or later) but would like to start using this firmware you can download+install Leaf Capture 11.5.2 for free, connect the back to update the firmware, and then resume using Capture One 6.3 (or later); Capture One will not overwrite/revert the new firmware.
