Kowa TSN-55A Zoom Kit

The Kowa TSN-55A Zoom Kit features high-quality optics that produce vivid, sharp, and lifelike images, while still being built in a durable and compact way that meets the requirements of adventurous birders. This kit comes with a fixed 17-40x wide zoom eyepiece attached. 

Also available as a Kowa TSN-55S Zoom Kit.

Quality optics

The 55mm pure fluorite crystal objective lens and ED optics deliver exceptional clarity and brightness. This ensures high transmission throughout all visible light wavelengths for true colour representation free of chromatic aberration and negative optical distractions. The TSN-55A also features unique optical coatings that control refraction and reflection within the lens. 

Compact and lightweight

Prioritises portability without sacrificing image quality for the ideal travel companion. Flourishing in outdoor adventures, birding, and exploring new landscapes, the TSN-55A PROMINAR weighs only 965g and measures 255mm in length, fitting in the palm of your hand or easily in a travel bag. 

Rapid focusing

The spotting scope’s dual focus system is integrated for rapid and fine-focusing adjustments, to quickly adapt to changing scenarios and easily capture intricate details. 

Fixed 17-40x zoom

The fixed eyepiece offers a 17-40x magnification range and the Prominar wide-angle zoom eyepiece technology brings up to 52% expanded field of view and complementary compact nature to the scope, compared to previous models. 

Ergonomic features

User-focused ergonomics such as the filter thread for adding protective filters, the twist-operated sun shade, and the secure tripod mount allowing for a stable connection to any tripod or monopod, provide this kit with ultimate versatility. 

Built for adventure

The body is completely sealed and nitrogen-filled, making it fully waterproof and able to withstand challenging environmental conditions. The objective lens is safeguarded by Kowa's innovative KR coating, which repels dust, dirt, and moisture, ensuring clear, unobstructed viewing during any expedition.
