Zeiss Digiprimes
High Precision Focus
DigiPrime lenses are designed to achieve and hold the most critical focus. The focus drive mechanism has been scrupulously engineered to eliminate backlash and play.
When focusing, the image remains pertectly centered. There is no tilt, rotation, or shift. Each DigiPrime lens is designed to be virtually free of breathing, so focusing does not influence image size. Changes in aperture have no effect on focus.
Absolutely Precise Back-Focus
Precision back-focus is critical to properly calibrated focus scales & perfectly focused images. Which is why DigiPrime lenses were designed with a highly refined back-focus mechanism that ensures accurately maintained focus scale calibration across the entire focusing range. Back-focus scales are clearly engraved for exact repeatability. Once desired back-focus is achieved, the dependable locking feature fastens the mechanism securely in place.
Innovative Iris
The Carl Zeiss team collaborated on a revolutionary new iris design exclusively for DigiPrime lenses. The result is the best diaphragm system ever created for video or motion picture lenses. Free from lag, slop or backlash, the new iris utilizes nine blades to deliver circular diaphragm openings. This results in pleasing and natural-looking highlights, and detail in soft-focus areas of the image.
Optimum Wide Open
In minimal light situations, DigiPrime lenses provide maximum creative control over depth of field. Like no other cinematography lens, the new Carl Zeiss design allows for shooting with the aperture fully open. It provides for unsurpassed contrast by minimizing flare, veiling glare and internal reflec-tions, well below any other lens. DigiPrime lenses deliver a crisp image with accurate contrast under the most demanding front lit conditions.
Floating Element Design
While engineering their famous Ultra Prime® lenses for 35mm filmmaking, Carl Zeiss perfected the floating element design, whereby lens groups move precisely in relation to each other during focusing, to correct image area curvature & related optical aberrations. The DigiPrime lens design effectively makes use of floating element groups to eliminate field and edge distortion, yielding sharp, high-resolution images across the field of view – even down to the closest focus.
