Phase One IQ250

Phase One's 50-megapixel IQ250 gives pro photographers a CMOS sensor option

Just days after competitor Hasselblad tried to upstage it with similar news, medium-format camera maker Phase One announced a new digital back that, for the first time, employs a CMOS image sensor. Unlike the Hasselblad model, however, Phase One's new 50-megapixel IQ250 is shipping now.

Until now, the medium-format camera market stuck with an earlier sensor technology called CCD (charge-coupled device) for converting photons into data. Now this high-end market segment is following the rest of the digital camera industry to CMOS (complementary metal-oxide semiconductor) technology, the same manufacturing approach used to build conventional microchips.

The IQ250's new Sony-built sensor offers options for medium-format shooters, including high-sensitivity performance up to ISO 6,400; exposures as short at 1/10,000 of a second and as long as one hour; and a dynamic range spanning 14 f-stops for a better ability to capture details in both shadows and highlights. It doesn't take advantage of CMOS sensors' superior ability to shoot video, but that's no surprise or even shortcoming given that Phase One sells machines designed solely to capturing the best still photos possible.
