4.0 Introduction to the IQ1 Series Digital Back

System Overview

The Phase One IQ1 Series Digital Back is designed to t on the Phase One

645DF+ as well as several other brands or models of medium format cameras.

The Phase One IQ1 Series include four dierent models; the IQ180, IQ160, IQ150

and the IQ140 that feature maximum resolutions of 80, 60.5, 50 and 40 high

quality megapixels respectively. (The IQ150 and IQ140 have a slightly smaller

sensor than the other two models that produces a lens multiplication factor

of 1.3).

All of the CCD-based backs have a dynamic range of 12.5 f-stops, while the

CMOS sensor used in the IQ150 has a dynamic range of 14 f-stops. The IQ1

backs are the rst product of their kind to feature a USB 3.0 connection,

facilitating faster image transfers in the future. The backs also feature a

FireWire 800 connection, ensuring the fastest tethered capture speeds

possible today.

All four models also incorporate a newly-designed 3.2 inch touch display

that features 1.15 megapixel resolution. The wide format display allows for

a full 4:3 aspect ratio VGA resolution image next to histogram, highlight

warning, focus mask, File Info, and touch controls. This touch screen display is

complemented by Phase One’s intuitive 4-button navigation.

Phase One’s patent-pending Sensor+ technology, built into the Phase One IQ1

CCD Series models, supports a variety of shooting conditions. Images can

be captured at full resolution or, using Sensor+ mode, switch instantly to

capture images with 20 megapixels* resolution at 4 times higher sensitivity,

up to ISO 3200.
