 Bausch and Lomb Opticals is in Rochester New York, a firm started by old Germans and is still in business. They make Nice binoculars,microscopes and eyeglasses,too. Bausch and Lomb and Zeiss Tessars are of equal quality. F6.3 Tessars are superior to F4.5, sharper and cover a wider angle. This is true even when the F4.5 lens is stopped to F8. |
