Excellent scope, which still provides one of the best views on the market. I've owned Kowa TSN3/823, Swaro ATS65HD/AT80HD and Leica APO77, all of which are of a similar vintage, but none of which surpass this scope optically. It can be purchased used for as little as 500, which can only be described as a bargain. Such a shame that Nikon never developed a WA zoom for the scope. The 30x DS provides one of the best views available, and for a little more power, the 50X offers an excellent higher power alternative to the zoom.
