Overview — Phase One 645AF

The Phase One 645AF is a professional medium format camera body built around the Phase One 645 lens mount. At its core is an 80MP medium format sensor capable of producing images at a maximum resolution of 10328x7760 pixels, delivering an extraordinary level of detail that makes it a compelling choice for studio photographers, commercial shooters, and fine art practitioners who demand the highest possible image fidelity from their capture system. The camera uses a phase detection autofocus system, bringing reliable and responsive focusing performance to a medium format platform.

The optical viewfinder provides a direct, clear view of the scene — a characteristic that many professional photographers continue to prefer for precise composition and accurate color rendering in the field. The camera accepts Phase One 645 mount lenses, giving shooters access to a dedicated ecosystem of medium format glass designed to match the resolving power of the sensor. While the specifications data available is limited in scope, what is confirmed points clearly to a system built for one primary purpose: maximum resolution capture.

For photographers whose work demands files with exceptional pixel counts and medium format image characteristics, the Phase One 645AF represents a serious professional tool.
