I had a pair of binoculars looking for, with which you can very well see the stars, the major planets and galactic nebulae one hand, on the other hand as well (without a tripod) as birds or simply beautiful landscapes. The glass should be, if possible, not too big and heavy and have a very good optical performance. After hours of research, also in countless forums, I was actually of the opinion that both can not. Either night sky or nature. If you look at the whole thing very special, this is also not completely wrong. But after purchasing the Canon 18 x 50 IS ALL WEATHER, I think: It really works! Except for the not really optimal eyecups (too hard and not ergonomic) I am delighted with the performance of the glass. I am a photographer and, of course knows exactly what optics can afford today. I can do without endless comparisons having to determine whether a lens or binoculars provides a sharp image or not. I still have a Leitz binoculars and a 10 x 50 China-product of Aldi. (Very lucky, is the thing adjusted well :)) By this glass I had just fun to get "star look". So now the Canon: I can not fault what sometimes is discussed in forums empathize with the exception of the already mentioned eyecups; let alone confirm. The optical quality is the price and is very good. Certainly could be even more effort still very low and almost non-interfering chromatic aberration even further decrease, then you would probably quickly but 20 x 60 glass move in the regions (perhaps comparable) Zeiss - ie at nearly 6,000 euros. The optical image stabilizer is just awesome. Without this even I could not keep quiet so that it would really bring joy this 18x glass. The focus wheel is running ultra-smooth and can be moved comfortably light. Due to the low depth of field focusing is a breeze, and like nothing I had ever in my hand. The brightness of the image is much better than a 50 mm opening suggests. Biliggläser need 80mm and longer for it. Stars should not be better observed with a 18x glass from his hand .; certainly not with stabilization; for the IS system is not designed. Mounted on a sturdy tripod is the glass (especially when contemplating the moon) all his sharpness. The smaller craters appear so realistic as if you were already on the way to the moon. The four large moons of Jupiter can be seen knackscharf. Open star clusters and galactic nebulae inspire. Back to Nature: Good 1200g want to be worn only once. On the supplied "belt" which is not recommended. Better with the bag in the backpack. To protect the lenses (without bundled caps!) I have two 58mm Walimex UV filter in front screwed. Can you close the whole with Canon 58 mm lens caps. Then the all-round quality rubberized, splash-proof device is well secured. The handle convenient location on / off switch for image stabilization is just awesome. With the funds or index finger, he is easy to use. In particular, the very short focusing distance slightest enjoy. From just over 5 meters, the lens can be focused. That is as if you are staying less than 30 cm away from the object. That the device has a pleasant internal focusing should also be mentioned. The viewing distance is easily adjusted by simultaneously moving the eyepieces. Commercially available batteries (AAA) suitable for IS-operation; But of course, the glass can also be used without batteries; but then without IS. To a certain extent, the Canon 18 x 50 IS is thus but a panacea, a glass in case that makes a lot of joy. Alternatively, there's also still the 15 x 50 ... If I had to forgive ten points, the 18 x 50 would get nine.
