This is the second binocular telescope brought to the market by Oberwerk in 2018, and it follows in the footsteps of its big sibling, the Oberwerk BT 100 (see remarks in separate post “Oberwerk BT-100XL-ED”,; Oberwerk has since also introduced a slightly smaller 70mm model). The 82XL competes head-on with the same size APM 82mm ED APO (see separate post, and delivers a comparable performance. BTs like this one with an affordable price tag, which satisfy both optically and mechanically and are beautifully finished, demonstrate the progress made by Chinese optics manufacturers in the last few years.
