For sale is an absolutely beautiful specimen of the Leaf Aptus line of digital backs. This back is mamiya mount and has been barely used, with a shutter count of 1754. It comes with one OEM battery, two 3rd party kastar batteries and a battery charger. The sensor is absolutely spotless with no marks whatsoever. Includes stylus, front body cap and plastic screen protector. 

If you know, you know. You will probably not see another leaf back again in this condition. I never got around to using this so I'm passing it on.
