Phase One IQ digital backs are the most advanced digital medium format camera backs available. A wide range of configurations are available to suit medium format and technical cameras including the Phase One XF.

The Specular team can advise which digital back is best suited to your work. At the heart of an IQ digital back is a CMOS or CCD sensor with resolutions from 40 megapixels to 100 megapixels.

What is the difference between CCD and CMOS sensors?

Every back is capable of capturing an extraordinary 16-bits of colour information per channel, with very large dynamic range. For the specialist photographer there are pure monochrome digital backs available: the IQ3 100MP Achromatic and IQ260 Achromatic backs delivering unsurpassed tonal information.

From the outset Phase One backs have been built with tethering to Capture One at the core of their architecture, so studio photographers benefit from fast file transfers and robust connectivity. Unlike DSLRs, the tethering ports on IQ backs are recessed to ensure cables do not move or get damaged in use.

Features of the Phase One IQ range of digital backs include:

  • 40, 50, 60, 80, or 100 megapixel options
  • 16-bit per channel colour
  • 3.2" high resolution touch screen
  • Simple touch menu navigation and four physical buttons
  • Zoom (up to 400%), pan, and browse full resolution images
  • USB 3.0 and FireWire 800 connectivity
  • CF Card slot
  • IIQ L (lossless) and IIQ S (lossy) RAW file compression options
  • Freedom to use on technical or 5x4 cameras
  • Basic Live View (40, 60, and 80 megapixel)
  • Video-like Live View (50 and 100 megapixel)
  • White balance tool
  • Focus mask tool
  • Bullseye level / virtual horizon

IQ3 Digital Back Range

With IQ3 digital backs offered in 50, 60, 80, and three 100 megapixel configurations, photographers get more advanced integrations and tools while including all the great features of IQ2 like WiFi connectivity.

The unique features of IQ3 are focussed on supporting faster integrated workflows including deep support for the Phase One XF Camera, and also adding convenient tools for users of technical cameras.

XF Camera Integration

On IQ3 it is possible to manage all you XF Camera setting on the digital back and through Capture One to enable easy shooting operation even when your camera is hard to reach.

XF Camera Power Sharing & USB Charging

The ability to provide consistent power for the back and camera body allows for maximum usage without the necessity to change batteries.

Advanced image preview tools

View your full resolution images with the Exposure Zone Tool to determine the accuracy of your exposure, and the Focus Mask Preview to confirm critical sharpness.

Features for technical cameras

The IQ3 series adds an internal exposure calculator, live sensor-temperature graph for managing heat buildup and noise, and electronic shutter capability (IQ3 100MP models only).

IQ2 Digital Back Range

IQ2 digital backs come in a 50, 60, and 80 megapixel configurations including the vaunted 60 megapixel Achromatic version. The addition of long exposure ability (IQ260 only), increases in dynamic range for the CCD sensors, and the built-in WiFi antenna distinguish IQ2 from IQ1 series backs.

Built-in WiFi Antennas

With IQ2 Phase One added WiFi. Connect to the digital back and preview your shots from the convenience of your mobile device.

GPS Data Recording

Using a paired iOS device running the Capture Pilot app it is possible to have detailed geolocation data attached to your images.

Long Exposure Mode (IQ260)

Phase One's advanced sensor design on the IQ260 unlocked the possibility of long exposures on a CCD chip.

IQ1 Digital Back Range

In order to support photographers who may not need advanced features and integrations available with IQ3, Phase One offer their most popular sensors in the IQ1 range.

We often recommend an IQ1 digital back to photographers who own cameras other than the Phase One XF, or who use technical cameras and have traditional imaging workflows.
