Phase One presents the first A-series medium format camera systems. Blending the best of Phase One and ALPA technology through highly-integrated precision components, these cameras are designed to capture outstanding images with greater convenience. The three Phase One A-series models include the A250, A260 and A280. They are based on the ALPA 12TC mirrorless camera body, plus a Phase One medium format IQ2 Aseries digital back — the 50 megapixel CMOS-based IQ250; the long-exposure-capable 60 megapixel, full frame IQ260; or the 80 megapixel full frame IQ280. Each model comes with the 35mm Rodenstock Alpar lens. There are two optional lenses available, including the ultra-wide 23mm, and the all-round 70mm, ALPA HR Alpagon, both offering edge-to-edge sharpness and the ability to resolve full frame medium format sensors.
