Phase One 645DF+

The Phase One 645DF+ builds on the success of previous generations of the camera and has undergone a complete overhaul of all moving parts to produce a camera with the highest uptime in the market of high-end photography.

The Phase One 645DF+ Camera System is designed to be a seamless extension of your creativity. Extraordinary capture becomes natural. Photographer, subject, hardware and software blend into one. The intuitive control of workflow delivers unlimited creative freedom.

The 645DF+ and 645DF cameras are the only 645 medium format cameras which supports both focal plane and leaf shutters, expanding photographers’ innovative possibilities by leveraging the two shutter technologies seamlessly for world class photography, whether this involves ultra-fast flash sync speeds or extremely flexible exposure times.

The 645DF+ camera introduces many performance improvements over its predecessor. An enhanced auto-focus delivers accurately focused images fast, even when shooting in low light or low contrast. The 645DF+ also offers a breakthrough workflow improvement — custom-shooting modes. For the first time in a medium-format camera, photographers can “dial up” a pre-defined mode, where the camera is instantly set up for a given shooting scenario, e.g. product, portrait or landscape photography.

Also implemented is an all-new custom adjustment feature photographers can fine-tune the alignment of digital backs to the camera. With this photographers can easily match their focus preference.

The Phase One 645DF+ Camera System easily matches integrated camera system while still being completely modular. It is highly responsive and features almost instant captures. It includes fast autofocus mode, particularly useful for instant captures at higher apertures. The camera will continue the same capture rate until the storage media (CF card or hard drive) is full or unable to keep up.

Shutter speed from 1/4000s to 60 minutes, B and X modes can match the extreme long exposure capability of the P+ digital backs or stop action with fast shutter speed or flash.
The mirror and viewfinder of the Phase One 645DF+ camera are almost three times larger than those of 35mm cameras, providing much greater control of focus and composition.
While hosting a complete list of features and custom functions, the Phase One 645DF+ camera is extremely easy to use. All settings important to the exposure are easily controlled by manual dials and soft buttons.

Freedom to choose the best back for you.

Lenses compatible with the 645DF+ / 645DF

One of the unique features of the 645DF+ camera is that is can take a wide range of lenses in either focal plane shutter or leaf shutter configurations.

Focal plane shutter lenses don’t have a shutter in them, they use the blind in the camera body to facilitate shutter speed. This means that we can get shutter speeds to to 1/4000 sec. Because there is no shutter in the lens, the cost of each lens is less than that of a leaf shutter lens.

Leaf shutter lenses have the shutter in the lens. This allows for faster flash sync (up to 1/1600 sec) when using flash lighting.

The 645DF+ camera can automatically switch between focal plane mode and leaf shutter mode.
