PHASE ONE IQ180 & H4X KIT
The H4X camera body is build upon a H4D camera unit with a DRIVE button instead of the ISO/WB button, which requires tight integration with the digital back.
The firmware is tailored for the H1/H2/H2F, and it offers the following new functionality:
• support for all H System lenses, including the HCD 28mm, HCD 35-90mm with the limitation of a slight performance decrease at edges when used with a 60Mpix or 80Mpix sensor
• support for TrueFocus
