These were perfect for the price, The autofocus feature makes them great for picking up and looking at something in a hurry, like a moving aircraft. The autofocus also makes it easier to keep moving objects in focus.
The only problems are that sometimes it is hard to focus on an object if there is something in the foreground of your field of veiw. (i.e. I live alongside an airport and there are a lot of trees in my yard so if i try to look at something at the airport and get a branch or something in part of the view your eye seems to naturally want to focus the branch and not the distant object) that is a pretty minor con i might add, it just takes a second to get your eyes to focus in the background. The other con is that the eyepieces aren't as comfortable as I would have liked.
Overall, these are great binocs very cheap, very effective, worth every penny and then some. I definitely recommend them to anyone.
