4.0 Introduction to the IQ Series Digital Back
System Overview
The Phase One IQ 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 IQ Series include three dierent models; the IQ180, IQ160 and
the IQ140 that feature maximum resolutions of 80, 60.5 and 40 high quality
megapixels respectively. (The IQ140 has a slightly smaller sensor than the
other two models that produces a lens multiplication factor of 1.3). All of the
backs have a dynamic range of 12.5 f-stops. The IQ backs are the rst product
of their kind to feature a USB3 connection, facilitating faster image transfers
in the future. The backs also features a FireWire 800 connection, ensuring
the fastest tethered capture speeds possible today. All three 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
IQ 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.
