Achromatic Sensor
The Achromatic 151-megapixel BSI sensor is produced without the Bayer color filter, allowing light to reach the sensor unobstructed. Without the filter, each and every pixel of the sensor captures significantly more light, ensuring absolute detail and luminance.
The Achromatic can capture much more than the naked eye is able to see, as it is designed to capture a broader spectrum of light. With the option to also capture light outside the visible spectrum, creative possibilities for infrared applications are endless, making the Achromatic the most light-sensitive medium format digital system available.

Built on the Infinity Platform
At the core of the IQ4 is the Infinity Platform, which lays a powerful foundation for image quality advancement, workflow transformation and feature evolution.
The Infinity Platform is built to grow, expand and adapt, allowing Phase One engineers to explore new possibilities in digital imaging and approach conventional photographic methods from new perspectives.
With the Phase One Lab program, every IQ4 photographer is invited to help shape the future of their camera, with access to exclusive beta features.

Full frame medium format
The full frame medium format sensors found in IQ4 Digital Backs, 1.5x the size of crop sensor mirrorless medium format and 2.5x that of full frame DSLR, allow you to capture more data, providing more detail and impressive results so that you can achieve your creative vision straight out of the camera.
With the expanded output flexibility provided by the high resolution and up to 15 stops of dynamic range, your workflow options grow exponentially.
Powerful workflow flexibility
Whether you shoot in a studio or in the field, the IQ4 is primed to complement your shooting style with modularity, capture customization, purpose-built automation tools, and features to assist every photographer.
The result of this flexibility is a personalized workflow that transforms the camera into an integral extension of your creative process.
Capture One Inside
The cutting-edge RAW editing core of Capture One has been directly integrated in the Infinity Platform, providing advanced control within preview and image settings, and opening the door for future customization of the RAW file at the time of capture.
Capture One Inside ensures the most efficient and controlled capture workflow, bringing the capture and post-capture workflows closer together than ever before.
Today, Capture One Inside delivers:
- Custom IQ Styles
- 4k JPEG processing in-camera
- Powerful image quality and preview performance
- Enhanced Live View, faster frame rates


Dual storage
With both XQD/CFexpress and SD card support, the IQ4 gives you the flexibility to store captured files in a way that suits your workflow. Save a backup RAW or process a JPEG to a second storage option, or simply expand your total storage so that you can focus on getting every shot.
Improved black calibration
The IQ4 improves the process of capturing the black reference data necessary for providing the absolute best image quality. This improvement streamlines workflow efficiency, especially for long exposures, offering incredible time savings.
Future-proof tethering options
Attuned to the professionals’ workflow, multiple tethering options capable of handling the high bandwidth are included in the IQ4 – Ethernet, USB-C and Wireless. All tethering and local storage options can be combined and customized to address your specific workflow needs.
Wireless
Wireless tethering can be used to transfer RAW files to Capture One in addition to storing them in-camera. This solution can be used as a backup or as part of a custom workflow. In addition, the AdHoc Wifi connection provides a direct connection to any device via Capture One or the upcoming Cascable Mobile App, to extend workflow and capture flexibility.
Ethernet
Ethernet grants the potential for a fully customized, integrated and dynamic workflow, and the flexibility to capture into or through any Ethernet-supported device. In addition, the long cable lengths and power provided via Ethernet eliminates workflow concerns surrounding battery power or cable length.
USB-C
USB-C provides a standard port type for convenient tethering on a wide variety of common devices. USB-C also delivers multiple power integration options, including powering your IQ4 via common USB-C power banks.
Ethernet and USB-C allow data transfer and system integration with no additional accessories necessary – transfer from local storage to any host without removing the card. And with a variety of cable lengths available, both Ethernet and USB-C can be exactly configured to suit your workflow needs.
