The H4D-200MS is not actually packing a single 200-megapixel sensor. Instead, the camera uses Hasselblad's multi-shot technology to combine six consecutive shots taken on the camera's 50-megapixel sensor into one higher-resolution final file. The sensor is moved in 1 or 1/5 pixel increments before each photograph in order to collect the maximum amount of information for a scene.
In addition to the six-shot mode, the camera can also shoot four-shot and single-shot photographs. The multi-shot technology is for still-life and studio shooting, as it requires and absolutely still scene and camera for up to thirty seconds. However, the single-shot mode can be used to capture live subjects outside of the studio.
Hasselblad is offering upgrades for H4D-50MS owners for about $9,800 (7,000 Euros). The camera will need to be shipped to the Hasselblad factory in Copenhagen, Denmark where its firmware and hardware will be updated to transform the camera into a H4D-200MS.
