[1:12.5] This is the best Spotting scope I have owned! It is replacing one that cost almost double last year. The Kowa is crystal clear to the edge and is great in low light conditions. I went with a straight 30x eye piece and couldn't be happier. I use the spotting scope on back country hunts because it is light weight and an unbelievable piece of glass. I will be adding more Kowa to my list of fine optics. 5

[8.5mm] High quality optics in a lightweight portable package. I am very impressed with the quality of this product. Construction is first rate and very solid with good ergonomic features. The optics are amazing with no color fringing or distortion. I use the scope with a KOWA TSE-Z9B 20-60x eyepiece, another quality item. I am amazed every time I use this scope at the distances I can see, with such detail! I can spend hours looking through the scope enjoying all the detail that has been hiding in plain sight. You can even get photos using and iPhone held up the eyepiece The image is surrounded by a black circle but the detail is amazing. I would recommend the CNW-10 Kowa Cordura Carrying Case. The case is great and is very fast to open and offers protection from bumps and scrapes. You will also need a solid tripod and head as any vibration is easily seen at the high magnification this scope is capable of. 5

[8.5mm] We are very pleased with the quality of this item. Our experience with B&H was very positive. 5

[9] The size and weight make this spotting scope easy to pack and it gives up little to nothing in performance to much larger units. This one will not get left behind. Since the unit is so light, a heavy tripod is not necessary also saving weight in your pack. Bought the anniversary version which came with a cover and even with the cover it only weighs about 2 lbs. 5

[9] This stope is very sharp, small and light weight. We will use it to view wolves and bears in Yellowstone as well as the birds near our home. It is easy to use and the cover protects it nicely. Highly recommended. 5

[MFT] I have been looking for a compact travel scope for a while. The alternatives (such as Nikon ED50 or Vortex Razor HD) always felt too much like a compromise. This one is a real jewel and on a par with some of the best spotting scopes of the 65mm class. Pros: - Small and light - Smooth and reliable focus - Bright image for a 55mm scope - High resolution, even at 45x magnification - Useful magnification range - Comfortable eye relief for wearer of glasses Cons: - Relatively small field of view (normal for a zoom eyepiece) 5

[1:12.5] This is a superb, high-quality spotting scope. Very clear optics and performance. It is light-weight but powerful. I upgraded to the Kowa from a large, bulky scope that I never liked and very happy I did so. 5
