The system is based around a new IQ3 digital back, which is available in 50, 60, and 80-megapixel flavors. The 80-megapixel version is actually exclusive to Phase One. But, medium format has always been able to pull of big resolution. One key difference here is the new AF system, which they call the Honeybee Autofocus Platform. According to the press material, it’s built on entirely new electronic architecture and has a white spectrum (not infrared) focus assist beam to help it lock focus faster. For shooting action or really anything outside of a studio setting, that could make a significant improvement in shooting experience.
