Discover the Kowa TSN‑99A Prominar spotting scope with 45° angled view and TE-11WZ 2 eyepiece
Introducing this high-end spotting scope from Kowa: exceptional performance, distinctive design, and optimal comfort in the field.
Pure fluorite optics and XD lens
The optical core features a pure fluorite crystal lens combined with a concave XD lens, virtually eliminating chromatic aberration even at high magnification. The color brilliance is simply stunning.
Advanced optical coating and light transmission
The optical surfaces benefit from a multi-layer apochromatic coating, specially optimized with proprietary Kowa KR technology, to repel dust and water and deliver outstanding image clarity even in challenging conditions.
Dual focus knob: Fast and precise
The dual-action system allows you to acquire your target quickly, then refine the focus with extreme precision, operable with or without gloves. Ideal for digiscoping or observing fast-moving subjects.
Ergonomic design and premium materials
A magnesium alloy housing manufactured by thixotropic molding ensures the perfect balance between robustness and lightness. It features a unique, fluid, and elegant style, designed for intensive field use.
Comfortable 45° angled viewing
The angled view enables natural, fatigue-free observation whether you are seated, standing, or in a hide. Ergonomics designed for prolonged observation.
TE‑11WZ II zoom eyepiece 30–70×
The supplied eyepiece offers variable magnification from 30× to 70×, with a constant eye relief of 17 mm and a field of view 20% wider than the previous model, ensuring a sharp image up to 70× without chromatic aberration.
Field of view at 1000 m and exit pupil
With the TE‑11WZ II on the TSN‑99A, the field of view ranges from 35 m (at 30×) to 20 m (at 70×) and the exit pupil from 3.3 mm to 1.4 mm depending on the zoom level.
Minimum focusing distance 6 m
Focusing is possible from approximately 6 m, which is remarkable for a spotting scope of this size and perfect for close-range digiscoping.
Weather resistance
Certified waterproof and nitrogen-purged, this spotting scope resists humidity, internal fogging, and water splashes, ensuring reliable use even in drizzle.
Optimized portability and weight
Despite its 99 mm objective lens, it weighs only ≈ 1,810 g (body + eyepiece), thanks to the ultra-light magnesium housing. A solid and portable companion for birdwatching or digiscoping.
Digiscoping adaptation and accessories
Compatible with the Kowa digiscoping adapter range (TSN‑PA7A, TSN‑DA10, TSN‑EX16), it can be converted into a super telephoto lens for DSLR, mirrorless, or smartphone.
Rotating tripod collar
The mounting collar allows for indexed rotation of the tube, so you can position the eyepiece without shifting the viewing axis—very practical on a tripod.
Retractable sunshade
The integrated sunshade protects the objective lens and enhances contrast in strong side light or humid conditions.
Striking visual design
The spotting scope features an elegant and minimalist silhouette, with carefully designed curves that set the kowa tsn-99a apart as an exceptional piece, both aesthetically and functionally.
High performance in low light
The 99 mm objective combined with fluorite and kr coating delivers remarkable performance at dawn and dusk, with a high twilight factor (> 50) for a bright image even in low light :contentReference[oaicite:7]{index=7}.
Outstanding user experience
User feedback highlights the incredible sharpness, brightness, and a wider field of view than competing references, especially for long-distance observation.
Versatility of use
Ideal for birdwatching, wildlife observation, digiscoping, distant landscapes, or astro-nature tourism thanks to its zoom power, stability, and visual clarity.
