Phase One’s IQ3 series of digital backs are the top of the line. These backs produce unmatched image quality and represent the future of image making with features like wireless camera control, live view, capture, rating, and review through the Capture Pilot app. IQ3 series backs also feature advanced image review options, XF camera menu on rear LCD, power sharing with the XF body, and 5 year warranties. Four models make up the Phase One IQ3 series of digital backs, including two CMOS sensor digital backs and two CCD sensor digital backs.
The new kid in medium format photography, CMOS sensors provide greater speed, ISO performance, and more fluid live view than their CCD counterparts. These backs can be found in both the 1.3 crop factor 44x33mm sized 50 megapixel sensor and the full frame 53.7×40.4 sensor of the 100 megapixel. Both these backs feature impressive dynamic range, up to 60 minute exposure times, and responsive live view.
The flagship of the Phase One IQ3 series lineup, the 100 megapixel digital back is a workhorse capable of unmatchable image quality. Boasting the greatest dynamic range of any other Phase One digital back at 15 stops, as well as a mini-HDMi output to take advantage of its fluid video like live view, the IQ3 100 is on another level. The 53.7×40.4mm full frame sensor housed in the IQ3 100’s aircraft grade aluminum chassis is capable of 16 bit color and a top ISO speed of 12,800. And with this back’s excellent noise performance, you won’t have to stop shooting after sunset.
The IQ350 is built for speed. At 1.8 frames per second using a focal plane shutter, this back can keep up with whatever you throw at it. While its 44×33 sensor is smaller than full frame, its file size is more than manageable and still is significantly larger than 35mm sensors. The IQ350 produces a quick, responsive live view feed that makes manually focusing a breeze even in low light. The IQ350 is also capable of 14 stops of dynamic range, and like all IQ3 series digital backs, can wirelessly connect to capture pilot for camera control, live view, and image review from a distance.
While slower than their CMOS counterparts, CCD sensor digital backs boast incredible clarity at low ISO. The original sensor of choice for medium format photography, the 80 and 60 megapixel digital backs in the IQ3 series boast phenomenal image quality. Whether they’re on a technical camera or a DSLR, CCD backs are a force. Both CCD backs in the IQ3 series lineup feature Sensor+ technology which effectively reduces resolution in exchange for increased ISO performance and speed while still using the entire sensor. This technology allows CCD backs to adapt to failing light and dynamic shooting scenarios.
The IQ380 digital back is the second highest resolution model in the IQ lineup. It’s full frame 53.7×40.4 sensor produces incredible sharpness at low ISO, and its capture speed can be sped up to 1.1 frames per second when using Sensor+. With features like long exposures up to 60 minutes, XF power sharing, wireless camera control, Sensor+, and advanced image review tools, the IQ380 is ready for whatever you throw at it.
The Phase One IQ360 hits a bit of a sweet spot in the IQ3 lineup. While still full frame, the IQ360’s 60 megapixels of resolution makes for a smaller file size than the larger 80 and 100 megapixel backs. This allows photographers to capture more images and be more versatile. Like the IQ380, the IQ360 is capable of hour long exposures and outstanding image quality at low ISO. Sensor+ allows the IQ360 to adapt to dynamic lighting conditions by improving ISO performance, speed, and reducing resolution while still using the full 53.9x40x4 sensor.
