Fluorite optics based on larger models

The TSN-66 utilises optical solutions originally developed by Kowa for the TSN-88 and TSN-99 models with large objectives. The fluorite crystal lens and improved optical coating allow light to pass through efficiently across the entire visible spectrum and produce an image free from chromatic aberration. The KR coating on the front lens repels dirt, moisture and dust.

Dual focus for quick and precise adjustment

With the quick-focus mechanism, the subject can be brought into focus in just a few turns, whilst the fine-focus mechanism allows for fingertip adjustment to fine-tune the focus. The rotating sunshade features a viewfinder that helps you find your subject more quickly.

Compatible with Kowa System accessories

The accessory collar and bayonet mount are compatible with the entire Kowa System range of accessories. This model is also available as the TSN-66S version.
