I got them this morning. To say that I am impressed would be an understatement. Optically even without the IS turned on, they are quite good. I was able to do my reading "test" on a sign across the street that has large, medium, small, and really small print on it. I could read the large, medium and small. But the really small print is something that I can only read with binoculars on a tripod. I pushed the button, and wow, I could read the really small print. With EASE. Sharp. No hint of any electronics doing their work that I can see.
They eyecups are perfect for my eye sockets. I can almost completely block out side light. I expected a bit of tunnel vision, with the FOV not being very big, but I don't feel that at all. They are brighter than I though they would be, but they definitely aren't for darker scenarios. I was able to track a squirrel very easily as he scampered around my back yard looking for food to stash. Easy to follow him, and the focus wheel seems fast, and has just the right amount of resistance that is very smooth. When he would stop and stay still, I was pretty much looking at a still photo of him. Impressive indeed. I was following him with the sun to his back, and I got NO flares or glare at all.
I really like the size of these, and the weight. I have fairly large hands, and they cradle very well. I like the indents where my thumbs rest. The magic button is easily operated my my middle finger, by pulling it back a bit so the fingertip can feel the button. At first I tried my forefinger, but that required changing my grip on the binocular. My forefingers rest naturally on the focus wheel. Perfect position.
I put a quick release wrist strap on them. I suppose when I go hiking I may put the neck strap on it. The case they came with is laughable. Canon? Seriously? I guess it protects them a little, but when you open it, the LOUD rip sound from the velcro would certain scare off any birds within a couple hundred yards. And the fabric could definitely be thicker. I know I will be getting a decent hard case for them.
My first foray into IS binoculars. I am definitely surprised at the optical quality. Whatever glass they used, is good glass with good coatings. And the ability to turn hand held views into temporary "photos" is pretty special.
I will be spending a lot of time with these.
