Phase One has released the IQ180, IQ160 and IQ140 medium format digital camera backs with 80, 60.5 and 40 megapixel CCD sensors respectively. All three backs feature 3.2" multi-touch rear screen the company describes as having 1.15 megapixel resolution (though it sounds più like what would usually be called 1.15 million dots). The IQ180 also features a USB 3.0 port for quicker image transfer and a FireWire 800 connection for faster tethered shooting. All three will be available from April 2011 at suggested retail prices starting from €16,990 /$21,990.
