spotting scope of the highest quality.
Always at the forefront of optical
excellence, the Kowa super telephoto
lens/scope draws upon decades of
advanced technology and development.
The Prism unit is built to accept Kowa’s range
of exceptional eyepieces* and when combined
with the pure fluorite crystal master lens,
they deliver an image of outstanding detail
and contrast.

challenges associated with telephoto photography.

scope system that does not compromise on optical quality.

focus on even the most challenging of subjects.
Unsurpassed
flexibility
One lens - three focal lengths.
The Kowa telephoto lens is designed to meet
the demanding needs of the telephoto
photographer, featuring a unique,
interchangeable focal length adapter system.
* When using eyepieces TE-9Z/14WD/9WD/17HD, the optional TSN EC3

Compact &
portable
For the photographer on the move, the Kowa telephoto lens offers an
outstanding level of portability. By removing the lens hood and focal
length adapter, the lens measures a mere 250mm (9.8”) in length.
The design of the Kowa telephoto lens/scope system delivers
unrivalled levels of transportability. Three telephoto lenses
ranging from 350mm, 500mm to 850mm and a spotting scope
can be carried in one small backpack. It’s the perfect travel
companion and first choice for telephoto expeditions.
Travel by air, land or sea - wherever your destination.
Out in the field, the Kowa telephoto lens weighs in at just 1.9KG*.
It’s a fraction of the size and weight of other high-end lenses with
similar focal lengths and optical quality.
Along with the standard 500mm f5.6, you may
choose the bright 350mm f4 or for even greater
telephoto work, the 850mm f9.6 adapter.
Featuring XD lenses, these adapters deliver a
level of sharpness worthy of the master lens.
Each adapter is available with a Nikon, Canon, Pentax, Sony/Minolta and Micro four-third mount.
