KOWA
LENSES
Drawing on our optical heritage
Kowa began from KALLOFLEX Auto-Mat in 1954 and continued to make the original
and unique camera KOWA SUPER 66 for around 25 years.
This optical ideology and technology, inherited from over half a century is revitalized
today with our new micro four third lenses – adorning the Kowa legendary PROMINAR
name associated with only the finest optics.

The super wide angle manual lens “KOWA PROMINAR 8.5mm F2.8”
has a diameter of 106 degrees. This greatly reduces TV distortion to a
value of just 0.12% producing high-definition pictures and movies.
Chromatic aberration is limited at the highest level due to XD lenses.

XD Lenses
Dual Link Iris
Kowa’s XD Lenses (extra-low dispersion
glass), when combined with a concave
lens possessing special dispersion
properties, reduces a very high
percentage of chromatic aberration.
A Dual Link Iris system make it possible
to choose silent or click aperture
adjustment.
Aperture settings can be changed in an
instant to suit the photographic subject.
Aluminium Alloy Body
Circular Aperture
The construction of the aperture blades
with 9 elements makes it possible that
the diaphragm shows a circle at all fstops, creating a more natural
impression.
All internal parts are protected by a
solid and rigid aluminium housing. The
body feels reassuringly well made with
good balance and weightiness in the
hand and when attached to a camera
body.
