Basically binoculars are made up of the objective lenses for long focal points, and the eyepiece lens, for short focal points.

    . It is very hard to determine the image quality with just a spec sheet. The easiest and surest way is to actually look through the binoculars. Please keep the following points in mind when purchasing binoculars. 1) Do you see only one image or two? Binoculars use two lenses parallel to each other

    . To greatly decrease the curvature of the field, Canon uses a field-flattener lens and an aspherical lens. With Canon binoculars, you will have beautiful image quality all round. 5) Is the image distorted? When looking through the binoculars, there are times when the perpendicular lines of windows
