Overview — Phase One IQ4 150MP

The Phase One IQ4 150MP is a medium format digital back built for professional photographers who require exceptional resolution and color fidelity. At the heart of the system is a 150MP medium format sensor paired with Phase One's Infinity Platform image processor, delivering a maximum resolution of 14204x10652 pixels — a staggering output that gives photographers extraordinary latitude for large-format printing, detailed cropping, and archival work. The sensor is rated at a native ISO range spanning ISO 50 to ISO 25600, offering flexibility across a wide range of lighting conditions.

The IQ4 connects to Phase One XF mount lenses, making it part of an established and capable professional ecosystem. For storage, the system accepts both XQD and SD media cards, providing redundancy options in the field. The rear display is a 3.2-inch touchscreen with 1.1 million dots of resolution, giving users a clear and responsive interface for image review and camera control.

Connectivity is a notable strength, with WiFi, USB, and USB-C all supported, enabling tethered shooting and wireless workflows. This is a purpose-built still imaging platform — video specifications are not defined, and burst shooting is not a feature of this system, reflecting its design priorities around maximum image quality over speed.
