Reading Time: < 1 minute

Just three days after Hasselblad announced it would launch the first CMOS-based, medium format camera, Phase One now claims its own 50-megapixel IQ250 CMOS medium format digital camera back is available from today.

A CMOS-based, medium format camera is said to offer increased ISO sensitivity and exposure time. The IQ250, which sports a 44x33mm sensor – 68 percent larger than traditional full-frame digital SLR sensors – has a dynamic range of 14 f-stops, an ISO range of 100 to 6400, and exposure times of 1/10,000s to one hour. The digital back also offers a live view option.

“We are very proud to introduce the Phase One IQ250, which carries on the tradition of Phase One high-quality, medium format gear,” says Henrik O. Håkonsson, CEO and president of Phase One. “The wider ISO range in this new CMOS-based system, for example, illustrates our desire to continue pushing the envelope for our customers, to help them succeed in all their unique imaging challenges.”

The new system is available now, retailing at €24,990 or $34,990. For more details, visit

On Tuesday, Hasselblad said it would wait until March to unveil new details about its H5D-50c, which will provide “a faster capture rate, longer shutter speed capability and much greater ISO performance”, according to the Scandinavian manufacturer.
