Pentax 645Z Firmware v1.10 Released

By PF Staff in Firmware Updates on Sep 25, 2014

Ricoh Imaging has just released the first firmware update for the Pentax 645Z: version 1.10.  This update adds support for the upcoming Image Transmitter 2 tethering software.  It also includes the usual minor bug fixes and stability improvements.

The Image Transmitter 2 software will enable USB tethering for the 645Z and will work similarly to the original Image Transmitter for the 645D.  We expect the software to become available for purchase before the end of the year.  It will be an alternative to the existing FLUCard wireless solution.
