Fluorite optics and accurate colour reproduction

The TSN-66 utilises optical solutions developed by Kowa for its larger TSN-88 and TSN-99 models. The fluorite crystal lens and improved optical coating transmit light efficiently across the entire visible spectrum, ensuring that no chromatic aberration is visible in the image. The KR coating on the front lens repels dirt, moisture and dust.

Dual focus for quick and precise adjustment

With quick focus, the subject comes into focus in just a few turns, and fine-tuning ensures perfect sharpness at the touch of a fingertip. This allows you to quickly bring a moving bird or game into sharp focus.

Weather-resistant magnesium frame

The body is made from a magnesium alloy, and the fully sealed construction is both waterproof and nitrogen-filled. The twist-up sunshade features a sighting point to help locate the target more quickly.
