With their ED and field-flattening lenses, Regal ED binoculars deliver a large, sharp field of view with very high colour fidelity. They have been specially designed to meet the needs of the most demanding binoculars users: bird watchers.
The ED glass with extremely low dispersion virtually eliminates chromatic aberration: there are no irritating colour fringing. This colour correction also ensures accurate focus and thereby a particularly sharp and bright image.
Compare the two images. The difference is especially noticeable in low light conditions, such as at dusk or dawn.
