Review of the Helios-ED 8×42 binoculars. Courtesy of Birdwatch Magazine. “The 675g of glass, magnesium and rubber – not forgetting the Argon gas filling – combine to form a binocular which I found light, compact and easy to operate….Slick mechanics manifest themselves in the smoothly turning, rubber covered focusing wheel, with just under 1.25 anti-clockwise rotations taking the image from close focus to infinity. It delivers pleasingly precise control with no play or looseness…. the twist-out , rubber eye cups lock loosely in three positions – fully retracted, extended and between the two – offering a maximum eye relief of 17.2mm. I was impressed with the exceptional wide field of view delivering , this puts the model in the premiership in this instance…The image delivered by the ED glass is also very good, especially when you take the price into consideration. Its nice, bright and very sharp across most of the field….The bottom line is I like this binocular, its ease of use and its overall optical performance”
