For years bird observation & photography have travelled side by side, now with this superb new modular system the two can combine with an ease never previously thought possible.

As A Spotting Scope

Making effective use of the outstanding optical system of the master lens, the telephoto lens can be used as a spotting scope by connecting it to the optional prism unit and eyepiece. Through the use of a simple and easy to use bayonet mounting system, switching between "photographing" and "observation" with the lens is easily accomplished. When used as a spotting scope, crystal clear images can be enjoyed since there is no focusing screen.

Digiscoping with a compact camera
By connecting a compact digital camera when configured for use as a scope, it is possible to achieve focal lengths of 1000-3000mm & more, allowing for photography of subjects at long distances which would not otherwise be possible. When configured as a scope, digiscoping is possible with a Kowa DA-4 & related accessories which are compatible with the Kowa TSN-880 series scopes.


As A Telephoto Lens

To minimize chromatic aberration (color blur) that occurs in long focal length lenses, the PROMINAR telephoto lens utilizes one pure fluorite crystal lens and two XD (eXtra-low-Dispersion) lenses. Bringing together the advanced optical technology fostered through decades of spotting scope development with the use of a fluorite crystal lens has produced a camera lens with extremely high contrast and sharp images.


Lightweight & compact design with outstanding portability
With the 500mm mount the whole package weighs about 1.9kg. The compact size makes it extremely portable & its lightweight design allows for hand-held shooting. Also, with a length of only 250mm (without mount) the lens can easily be carried in a small backpack.

Long hood with attached sight
A lightweight long hood is included as standard. The hood mounting screw has a special shape that allows it to be used together with the sight attached to the camera, aiding swift aiming when attempting super-telephoto photography.

Dustproof & weatherproof structure
The objective lens & focusing units utilise rubber O-rings to seal the housing of the lens for enhanced dust & weatherproofing.

Easy to use dual focus
The Kowa dual focus system has been adopted for the lens, providing two focusing rings; a quick focusing ring for rapid focus adjustment & a fine one for detailed adjustment.
