The sixth pair of binoculars in my life (now 73 years)! From 8 x 20 to 12 × 50 everything was previously doing. Depending Sehanspruch binoculars is always a compromise, but as the Olympus 8 x 40 is the vast majority of cases justice. For 2 hrs. Hike not too heavy, is the focus of her best in men's hands, the optical quality is mild only by 3 x expensive glasses marginally exceeded, especially me has positive about the sharpness at dusk. No luxuries like nitrogen filling, roof prism design, tripod mount, waterproof, impact resistance, etc., increase the price. I as a normal consumer look max. 1 hour / week through this glass and was not disappointed. Even had the good fortune to see on a clear night, the elliptical disc of the Andromeda nebula! I can not judge whether it is better for people wearing glasses since I always pick up my glasses for observation. An 8 x 40 lens has been optimized for as many purposes as 8 x 20 or 8 x 25 only have the small advantage of portability, but no offer visual pleasure due to the lower light intensity. To all who want to spend no 150 euros or more, I recommend this glass for just under 70 euros. Congratulations to Olympus !! Therefore full five stars for this product, which is in your hands quickly thanks to Amazon. J. Simons, 97999 Igersheim
