Phase One's Camera Technology

Explore the technology found in Phase One Camera Systems that takes your creative workflow and image quality beyond imagination.


Full Frame Medium Format

Phase One is dedicated to full frame medium format photography.

The sensors in Phase One's IQ range of digital backs are 2.5x larger than that of full frame DSLR cameras, and 1.5x larger than cropped sensor mirrorless medium format. The use of a larger sensor means more light, and therefore more information, is available when converting captured light into a digital file. The availability of more data allows us to honor the quality of that data, and this translates to a more efficient use of information with less interpolation.

With full frame medium format sensors, the quality of your RAW image more closely reflects your creative vision straight out of the camera. Output flexibility also increases exponentially thanks to the quality of detail, extreme resolutions and up to 15 stops of dynamic range.

Open Platform Philosophy

The Open Platform Philosophy is at the core of all we develop, allowing Phase One to deliver solutions which are both modular and future-proof. You gain the flexibility to choose the lenses, resolution, and system that fits your workflow and needs without sacrificing functionality. 

We listen to the needs of our photographers to develop the creative and workflow innovations you need to continually create at the highest standard.

The Infinity Platform

The powerful and flexible Infinity Platform lays a new foundation for image quality advancement, workflow optimization and feature development well into the future. 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. The Infinity Platform is able to dynamically expand and adapt to market demands and technological changes, providing you with a steady stream of new features and innovations aimed at ensuring that your investment allows you to continuously create at the highest professional level for years to come.


We have been inspired by our intimate knowledge of our own digital sensors, as well as 500+ different sensors from cameras supported in the Capture One software, to invest in what we consider one of the cornerstones of image quality - color. With the Trichromatic sensor, we have put decades of knowledge into action and, together with Sony, physically customized the sensor to get pure color without compromise, all straight from the sensor.

In the average sensor, the degree of color separation between the wavelengths of blue, green and red light is where the color compromise begins. The color filter array of the Trichromatic sensor, however, is designed to pick up exactly the right wavelength of light that allows us to get the most color nuances in the most natural way possible. This means that we achieve fully saturated colors, and can get every shade of blue, green and red, resulting in an image that is closer to the color definition of human vision than any other sensor.
