The Canon binoculars I use now for over a year and I still enjoy it when peace comes to picture when I press the button for the image stabilizer. However, the image will not completely silent. The high-frequency tremor goes away. Some movement is still present. A bit like when you're drunk. But you have not cramped trying to keep the glass and watch quietly relaxed. The eye has the ability to detect details and study characteristics. Even birds can be discovered which are betrayed by your movements. That goes with a normal appearance hardly because the entire image is always wagging. Also observations over a longer period are possible thanks to stabilizer. To track a bird of prey in the sky or searching the banks of a lake is not a problem. Make up flabby arms. The glass is no lightweight at 1.2 Kg. When wearing glasses, I can well see through the glass. The fold-out eyecups I do not use.
On the performance of a spotting scope, however, the Canon 15x50 IS AW does not come close. The half I also bought myself a good spotting scope. The I use when I know in advance that birds are far away. Or I specifically ansteuere an observation Punk and the spotting scope does not have to carry a lot. Otherwise, the Canon is my favorite companion and säßt Also then inserting when it is hardly possible with a spotting scope: for example, on a vibrating ship or in strong winds.
Negatives: there are only supplied protective caps for the eyepiece and when the protective case a sticker has been peeled off after a short time on the inside is to protect the glass from a metal rivet. The binoculars were then smeared with glue and the metal rivets for the Canon logo may now housing scratch. There's a star deduction.
Then still for sale: I have failed a year ago to find a shop where I could try out Canon binoculars with image stabilizer. Photo stores had it not in stock and want to try to not order. Shops with good optical range (eg for hunters) have Canon not in the program. So to test no chance before buying. I then ordered it online. Since you have the option to return it within 2 weeks and it's cheaper than a shop.
