The Carl Zeiss Planar® lens is the most successful
camera lens design ever created. This nearly
symmetrical layout provides the lens designer with
numerous means to correct aberrations extraordinarily
well, even for wide open apertures. The ideal basis for
high-performance lenses with great color correction,
high speed, flat image plane (this is where the name
comes from) and low distortion. The Planar® design is
the basis for nearly all professional ’workhorse’ lenses
on earth and in space today.
At f/2 the Planar® T* 2/80 lens is the fastest optic in
the Contax® 645 system. There is no faster Planar®
lens in medium format photography anywhere. Even at
full aperture the performance of the Planar® T* 2/80
lens is so high that professional quality images are
reached.

Especially so since the Contax® 645
autofocus provides for quick and accurate focusing,
where manual focusing
where manual focusing
would have been too slow or not accurate enough for
f/2. So the Planar® T* 2/80 lens is the ideal tool for
handheld photography with decent shutter speeds at
low light levels, like in people photography indoors,
celebrity portraits, wedding coverage and similar
demanding tasks.
With its focal length of 80 mm the Planar® T* 2/80
lens records an image with a perspective (size
relationship between foreground and background) that
is pretty much the way we see the scene with our eyes,
like a fast 50 mm lens on a 35 mm SLR. So it is suited
for almost any task in general photography, which
makes it a powerful and versatile standard lens in the
Contax® 645 system.
Preferred use: all-purpose, travel, editorial, people,
celebrities, candid weddings
