ZEISS has added a zoom to their line of lenses with interchangeable
mounts. With the Carl Zeiss Lightweight Zoom LWZ.2 15.5-45,
they are reintroducing a design originally available only in PL.
The new-generation Lightweight Zoom comes with interchangeable
mounts that allow the lenses to be used with a wide range of
cameras, from traditional cine to HDSLR systems. Three different
mounts are available: PL, EF and F mount. The LWZ.2 covers the
ANSI Super 35 image area (24.9 x 18.7mm / 0.980" x 0.7362").
Weighing around two kilograms, the LWZ.2 is comfortable
handheld, on Steadicams, with cine cameras, and also HDSLRs.
The LWZ.2 uses radically shaped spherical glass surfaces with a
very strong curvature, which guarantee high optical performance.
Large-diameter aspherical lens elements keep the lens lightweight
while reducing spherical aberrations and keeping the image free
of distortions. Straight lines stay straight, from infinity to closeup
and over the entire zoom range. The T* XP multi-layer coating
reduces flare and internal reflections, resulting in pleasing and
gentle colors, high contrast and deep blacks. (zeiss.com/cine)
