New 77mm and 88mm Kowa Spotting Scopes
Kowa, a favored brand among Highpower shooters, has started shipping two new lines of spotting scopes, the Kowa Prominar TSN-880 and TSN-770 series. These scopes feature 88mm and 77mm objectives respectively. Multiple interchangeable eyepieces are available including 20x-60x, Zoom; 30x, Wide; and 25x, LER (Long Eye Relief).
The key feature with these new Kowas, compared to previous models, is the quality of the glass and the size of the front objectives. All TSN-series scopes feature C3 fully multi-coated lens systems. The TSN-773/774 models have XD (extra low dispersion) objectives, while the premium TSN-883/884 models feature pure Flourite Glass lenses for reduced chromatic aberration and improved long-range resolution. The Flourite lenses add about $600 to the price of the scopes.
The new Kowas are quite compact compared to most other spotting scopes with similar objective sizes. The highly achromatized objective lens makes the 88mm Kowa as compact as a 60mm class scope, with the light-gathering ability of a much bigger lens. A new internal dual-focusing system also reduces overall length. With large “fast-focus” knob you can focus from 5m to infinity in just two quick revolutions. Kowa also claims the internal focus keeps the image steadier during the focusing process.
Both the TSN-880 and TSN-770 series scopes are offered with either straight or angled bodies. Bodies are magnesium alloy, and the nitrogen-charged housings are fully waterproof–meeting the rigorous standards of JIS Protection Class 7. The new Kowas are sold by Creedmoor Sports, Cabelas.com, and other major retailers. The TSN-771/772s (body only) cost $1,195 at Creedmoor, while the top-of-the-line TSN-883/884s with Flourite glass, run $2000.00.
We hope to test these new Kowas, head to head, against other premium spotting scopes, such as the Zeiss 85mm. Click HERE for a review from a UK birding magazine that concludes the Flourite-glass TSN-883 is nothing sort of outstanding–that it will compete with anything on the market: “With the launch of the TSN-880 series Kowa has clearly thrown down the gauntlet to challenge the Austro-German supremacy that has become widely recognised within the current optics market….This telescope offers almost everything: user friendliness, a large, light-gathering objective combined with a short body…and an image that is apparently second to none.”
