Vortex Skyline ED 20-60x80 Angled Spotting Scope

I had been wanting a scope for some years, and finally made this purchase when I saw this good looking, well made product in a high quality optics store. It was highly recommended by the owner of the store as a product as good as a Swarovski with a much lower price. It has a terrific warranty. However, while a good scope, I do not find it to be a great scope. It has three big drawbacks. First, it has a very limited depth of field in focus, so that if a swimming duck is viewed at distance at higher magnification, the head of the duck may be in focus while the rest of the body is not. Second, the focusing knob is very small, and requires an endless number of full turns to go from near to far focus. Third, the field is very, very dark anything much above the 45 magnification. Would I buy this scope again? Yes, marginally, as I do find it useful. However, don't buy it thinking you will get a scope that is quick to focus, or of the highest optical quality.
