The Phase One IQ250 Set includes everything you need to get started: XF camera body, digital back, batteries, charger and connection cable. The IQ250 is a digital CMOS back with 50 MP resolution. Due to the CMOS sensor it is much more flexible in the ISO settings compared to the older backs and it also offers live-view. The sensor has a crop factor of 1.5 and the image size is 8,280x6,208 pixels. 14 f-stops exposure range. Up to 1.4 images per second are possible. The system stores the image data on CF card or wired with the CaptureOne software directly on a computer. The sensor measures 44x33 mm and is thus significantly larger than a sensor in a so-called full format DSLR, which measures 35.8x23.9 mm. We recommend the IQ250 especially for fashion shots, as it offers a relatively fast image sequence at high resolution. Our set contains all you need apart from the lenses. Add the lens and you're ready to go!
