Ultra Prime T2.8/8R
With the new ARRI/Zeiss Ultra Prime T2.8/8R,
ARRI introduces a unique extreme wide-angle
lens that further extends the focal range of the
Ultra Primes to a total of 16 lenses from 8 mm to
180 mm. The Ultra Prime 8R is an unusual
specialty lens of stunning optical quality with a
revolutionarily small form factor.
The Ultra Prime 8R is perfect for commercials,
features and music videos because of its rectilinear
design (the ‘R’ in its name stands for ‘rectilinear’).
In contrast to a fisheye lens, a rectilinear lens keeps straight lines straight and creates an
image that covers the entire ANSI Super 35 aperture. Both the Ultra Prime 10 mm and 12
mm are also rectilinear wide-angle lenses. The Ultra Prime 8R is ideal for wide establishing
shots inside buildings or cities, sweeping vistas, the interior of cars, exhilarating high-speed
POV shots, small rooms, unusual angles and many, many more applications where a new and
fresh look is required. Because of its enormous depth of field and straight image geometry, it
is also extremely useful for shooting miniatures.
With the Ultra Prime 8R, Zeiss used the latest technological advances to keep the high optical
and ergonomic standard of the Ultra Primes in an 8 mm design. This was no easy feat since
the wider a lens gets, the more difficult it is to keep image quality at an optimum. This
explains why many lens manufacturers shy away from building extreme wide-angle lenses -
and building such a lens in a rectilinear design is even more difficult.
The front element of the Ultra Prime 8R is a radically shaped aspherical lens element that is
produced using semiconductor technology, resulting in high optical quality while substantially
reducing size and weight. In fact, the Ultra Prime 8R is smaller than the 10 or 12mm Ultra
Primes - a revolutionary size for an 8mm lens - and weighs only 2/3rds of the lOmm’s weight.
A small extreme wide-angle lens not only speeds up work on the set, it can also be employed
in unusual places. It gives the cinematographer ample room to place lights when working
close to the actors and allows the lens to skim past objects that are very close to the optical
axis for shots that were not possible before. As an extra benefit, the Ultra Prime 8R can be
used on the ARRIFFLEX 16 SR3 (when the viewfinder is rotated up for clearance, of course).
Special optical glass with anomalous partial dispersion, a floating element, exotic glass materials
and internal focusing do their part to ensure that the Ultra Prime 8R shares the family traits of
its siblings. Like the other Ultra Primes, the Ultra Prime 8R
• covers the whole ANSI Super 35 image area(24.9mm X 18.7mm/0.980“ x 0.7362“),
• is super color matched to guarantee seamless cuts between scenes and to avoid
time consuming color matching in post,
• has minimized chromatic aberration and almost no geometric distortion,
• shows maximum contrast and resolution consistently over the entire focus range including
unrivaled close focus performance,
• has an even illumination of the whole Super 35 field,
• shares special light absorption techniques and the new Carl Zeiss T'“' XP multi-layer anti-reflex
coating for greatly reduced veiling glare.
