Product description
Uses an objective lens with a diameter of 66 mm, which has a focusing power of 120% or more compared to a diameter of 60 mm. Furthermore, by adopting a special low-dispersion XD lens, it demonstrates exceptionally high optical performance with chromatic aberration suppressed to the utmost limit. In addition, it has a compact design with a total length of only about 10 mm compared to the 60 mm class, and weighs about 1 kg, making it an easy-to-use and highly mobile scope. It is a high standard standard model that supports a wide range of users from those who enjoy nature observation in earnest to those who are new to bird watching.
Compact body is comparable to a milk carton
Among the TSN-660M series, which features a compact body, the direct-view type TSN-664M has a slimmer design and is extremely portable. The total length is 312 mm and the mass is 1020 g, which is close to the size of a 1 L milk carton. The style with no noticeable protrusions fits neatly into your usual backpack or bag, making you want to carry it anywhere. It is easy to use not only for bird watching, but also for casual outings such as driving in the fresh green and autumn leaves season, lakes in the summer, and swan observation in the winter. Also, if you use a wide variety of adapters for each model, you can shoot with a smartphone or compact digital camera, so you can easily enjoy shooting and sharing.
Direct-view type if ease of use is important
The feature of the direct-view type is that it is easy to use. Since the main body and the lens are in parallel, you can capture the object as you imagined. It is possible to move the scope with the same feeling as the movement of chasing with the eyes while keeping one's body constant for moving objects such as flying birds. Also, the fact that you can set it according to your height and shooting posture is a nice place for beginners and users who are not accustomed to handling scopes. The small, direct-view scope is the easiest type to use. Of course, as one of the basics for veteran users, it can always be carried and used to determine observation points. Since the outside of the lens is coated with excellent water and oil repellency, it can also be used for hunting.
