Product description

Our expert comment:

These opera glasses follow the Galileo system. They have the advantage of extreme compactness, without the need for prisms. However, the exit pupil lies inside the instrument leading to the edge of the field of view being rather ill defined. This feature is typical of Galileo systems.

If sharpness right out to the edge of the field of view is wanted then the, not quite as elegant, classic design of binoculars is needed. For use at the opera or theatre, these opera glasses are fully sufficient.

(Marcus Schenk)
