We bought the binoculars, because a longer sailing trip is pending. The world market supply of stabilized lenses is very clear. After studying the buyer reviews and specifications, we decided for this type. The feel is very good, the material touches his pleasant and the glass is well in hand. It can also be easily adjusted to the diopter they need. The main characteristic of this glass, namely, the image stabilization works in two possible ways: on the one hand, one can a handily (for right-handers) placed tast for stabilizing press, as long as you need this feature, or the key you just type a short, then the function switched on for about 5 minutes. For operation you need 2 widespread batteries (or batteries) AA, which are well sealed in a rubberized cap at the bottom to achieve. A 15-fold magnification is a lot of wood. Without stabilizing the binoculars wobbles back and forth, in addition to the pulse make then also the physical effort while running and the Gewackel z. B. the ship so noticeable that you get very little useful results. The first attempt took place at night on the terrace enclosed (no wind!) Instead of in a starry sky. The Jupiter was visited and targeted through the binoculars with stabilizer. His 4 inner moons were clearly visible. If switch the image stabilization danced a little, at this magnification no wonder. Around looked in daylight in the area, completely new perspectives: what cooking there Mrs. Muller in the kitchen of 200 meters, about Dumplings? As Canon lenses used consisting of UD glass, that is, at Nikon and Pentax ED. These are optical glasses having a high refractive index and low dispersion. Applied to Photo focal lengths, we would have a small SLR with 750mm focal length. Each photo enthusiasts know what it would cost a lens. Without UD or ED glasses would emigrate secondary spectrum, resulting in color fringing and blurring. This is nothing to see here. High praise. Less well the following points have fallen, who have helped make "only" 4 stars were awarded: It is delivered in a relatively soft and narrow plastic textile bag. A hard-shell case I could find practical, especially when hunting and on a sailboat. Then there is no lens cover! The front lens smile to a completely unprotected. The rear Okularabdeckungen are hard to fix, they fall from just pulling out of the glass and tumble in the landscape around. The mounting strap is rather thin and could easily be replaced by a copy of à la camera strap. Given the price are already improvable points.
