I bought this item to go nature viewing and must say that it really is a great binocular for the price. The items viewed have a really nice 3-dimensional look to them and the diopter comes in handy even for someone with very bad vision like myself. The focus for this model (16 x 50 Wide Angle) is a flat tab between the barrels that makes it VERY convenient to use without having to look or stretch your fingers. It gives a very nice field of vision and has roll down eye cups, which is good just in case you want to wear your glasses or shades. The binoculars do shake a little b/c of the power of the magnification. And it can be a chore to hold for long periods of time b/c of its weight. It weighs about as much as one of Michener's hardback novels.
