Product description

KOWA TSN-500 series
The small scope with the big heritage. Introducing the new 50mm ultra compact, light weight spotting scope from Kowa.

Based on the success of our SV range of binoculars, where great value meets good quality optics with strong specification, the Kowa TSN-500 compact spotting scope sits at a new lower price point than previous scope models and opens up a potential new set of customers.

Marketing will be aimed at those wishing to aspire to own a Kowa optic and will serve as an introduction to a premium brand, a position that will strengthen as our brand continues to grow. The scope size, weight and specification will of course appeal to the travel, nature and hunting markets as well as appealing to both young and the more elderly consumer where portability is a key feature.

This new model enhances our overall product line-up of spotting scopes with a Kowa option to suit most budgets.

Customer reviews

First I'd like to say that the AstroShop staff was very quick, competent and helpful when ordering, so I can openly recommend them.

The scope itself does live up to the name. It's the best non-ED scope I have look through. In good light the image is clear and bright even at x40 (in very cloudy weather, dawn or dusk the physics of 50mm objective will limit you of course) . Focusing is very smooth and the overall built is polished and solid.

I have tested some other 60mm and 80mm non-ED scopes and here the combination of weight and image quality is better. You do not get the 60x zoom, but in non-premium scopes the 40-60x range rarely gives more details.

Also in the field the fact that you'll carry 400gr vs 2kg does make a big difference. Finally, this scope can also use a lighter tripod which will again weigh probably half as much as a full-sized one.

All in all, unless you can afford a premium ED, flourite scope, so far this is the best I have found.
