“The image is crisp, the colours are real and the definition is fantastic. The high light transmission factor (90%) makes these light-weight 10X40 binoculars as luminous as any good pair of 10x42, except of course the Zeiss Victory HT 10x42, with their amasing 95% of light transmission. The focus mechanism is smooth and requires little turning. This, together with its low weight means that I can use them with one hand when walking my dog. Very highly recommended.”
