Responsive dual manual focus puts you in control

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. 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. All three quickly and securely attach to the main lens unit and your camera body in seconds.
Supported mounts: Nikon mount, Canon mount, Pentax mount, Micro Four Thirds mount, Sony “A” mount*
Two products in one
No more agonising choices of what gear to leave behind - by attaching the optional bayonet fit TP-88EC1 prism unit, you can quickly transform the telephoto lens in to a spotting scope of the highest quality. 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.
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 scopecan 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.
