Wired has reviewed the Phase One IQ180 a medium format camera with a 80 Million Pixel sensor.
“Quite simply, it’s one of the sickest camera systems you can buy for any money — and we’re talking about some serious coin here. For $47,990, you get the back, the body, and a Schneider Kreuznach 80 mm LS f/2.8 lens.
The images produced by the 80-megapixel digital back are massive — upwards of 500MB each. If you were to pull a file straight out of the camera and print it out at full print resolution, your image would be about 34 inches wide. That amount of depth adds a level of clarity and definition to your images that’s truly stunning.”
