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 new 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.

Phase One Digital Lenses & Accessories, part of a complete solution

Phase One Digital Lenses

The Phase One Digital lenses are designed for maximum image quality and freedom of choice – using digital back or film, using full frame 645 sensor like Phase One P65+ or less than full frame digital sensors.

The Phase One 645DF camera is the only 645 medium format camera 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.

When used with the Phase One P+ digital backs, the image quality is further enhanced through advanced digital optimization in Capture One – the professional raw processing software supplied from Phase One.

Not only have all lenses been measured and profiled for automated enhancement in Capture One, also data regarding the specific position of the lens elements are captured and used for image optimization. This leads to absolute leading image quality with unique replication of the true colors, details and lightning of the captured moment.

Phase One Digital lenses uses eco‐glass, which contains no lead or arsenic, securing both better image quality and a nature‐friendly policy.

All Phase One lenses are supplied with a 3 year warranty. All Schneider lenses come with a 1 year warranty

Phase One AF 28mm f4.5 Aspherical D lens

This full‐frame ultra wide angle lens is the world's first medium format 28mm lens that can be used for film and digital backs. The use of aspheric lens elements produces outstanding optical performance.
The 28mm f4.5 D is a full‐frame, ultrawide lens that utilizes the latest aspheric lens technology to produce high resolution and large image circle coverage for film and digital backs. Since wide angle lenses can cause color shift problems with digital backs (due to the extreme angle at which light rays hit the sensor), the 28mm f4.5 D has been designed to direct light rays so that they are parallel when they hit the sensor – producing maximum sharpness, color accuracy and contrast.
Unlike conventionally designed digital lenses, the 28mm f4.5 Sekor D Aspherical was designed with the requirement that it works with digital and film systems. It is the world's first 28mm medium format lens with this capability. The Phase One AF 28mm f4.5 D is ideal for a wide range of applications, including commercial, architectural and outdoor photography.

Phase One MF 120mm f4 Macro D lens

Pinpoint sharpness with manual focus is confirmed from infinity to 1:1 magnification, without additional adapters, by a green diode in the finder. This lens provides a flattering perspective suitable for tight portraits, and permits good working distances in or out of the studio. It can be used for anything from extreme detailed close‐ups to full‐length portraits. The lens is manually focused (MF) and utilizes the digital focus confirmation in the Phase One 645 AF body plus auto‐diaphragm operation.

Anomalous dispersion optical glass is employed to reduce chromatic aberrations, which results in APO‐quality lens performance when focused from infinity to 1:2 magnification, and significantly reduces chromatic aberration from 1:2 to 1:1 magnification. The optical engineering and multi‐coatings of this lens achieve excellent color balance, high contrast and high resolution over the entire focusing range, which is an extraordinary accomplishment for a Macro lens. The barrel design reduces flare significantly.
