Uniform Size & Shape
Every DigiPrime lens features the same barrel diameter and length.
Each has a similar balance and center of gravity. Focus and iris
gears are uniformly positioned. Therefore switching lenses does
not require realignment of accessories such as matteboxes, lens
motors, or even fluid head counterbalance. In addition, all lenses
have a convenient 95mm front diameter. A perfect fit for film
lens accessories. And even when it comes to lens caps, one size
fits all.
Accurate & Visible Markings
DigiPrimes' lens barrel diameter provides ample space for oversized
scales and precise, easy-to-read engravings. The etched markings
are filled with long-life bright yellow or white enamel for high
visibility, regardless of ambient lighting. Like the finest cine
lenses, focus scales are viewable via a windowing system available
on both sides of the lens. Iris scales are also clearly visible
from either side. Zeiss has improved on conventional focus scales,
equipping DigiPrimes with around 300° of barrel rotation.
The expanded scales are individually calibrated for each lens
to facilitate pinpoint accuracy. As a convenience, the standard
focus ring, engraved in feet & inches, can be quickly changed
to meters. The equally advanced iris scale is marked in 1/3- stop
increments for ultra-accurate exposure.
Fixed Iris & Focus Gears
DigiPrimes' geared rings are positioned uniformly across the set.
Focus & iris scales are arranged in the ergonomically correct
order: focus in front & iris behind, next to the camera. Solid
construction under rigid tolerances is responsible for keeping
the focus and iris gear positions absolutely fixed even while
focusing. There is no axial travel and no play. Positioning external
lens motors & encoders is simplified, so there's less wear
and tear. Lens changes are simple, speedy and safe.
High-precision Focus
DigiPrimes 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 DigiPrime lenses,
the image remains perfectly centered. There is no tilt, rotation,
or shift. Each DigiPrime is designed to be
virtually free of breathing, so focusing does not influence image
size. Changes in aperture have no effect on focus.
Innovative Iris
The Zeiss team collaborated on a revolutionary new iris design
exclusively for DigiPrimes. The result is clearly the best diaphragm
system ever created for video or motion picture lenses. Free from
lag, slop or backlash, the new iris utilizes up to eleven 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 situations with minimal light, DigiPrimes provide maximum creative
control over depth of field. Like no other cinematography lens,
the new Zeiss design allows for shooting with the aperture fully
open. It provides for unsurpassed contrast by minimizing flare,
veiling glare & internal reflections, well below any other
lens. The toughest lighting conditions are now readily achievable.
Absolutely Precise Back-Focus
Precision back-focus is critical to properly calibrated focus
scales and perfectly focused images. That is why DigiPrimes 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.
Floating Element Design
While engineering their famous primes 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 and related optical aberrations. The DigiPrime
design effectively makes use of floating element groups to eliminate
field and edge distortion, and to yield sharp, high-resolution
images across the field of view even down to the closest
focus.from Zeiss DigiPrimes brochure
