This Trinovid 7×35 was made in the late 1960s. Leitz (today Leica) made several Trinovid models with Uppendahl prisms in the 1960s and 1970s, of which the 7×35 was possibly the best optically. At 7x magnification, the lack of phase coating did not have the strong negative effect on image contrast as in the 10×40 (see separate post Leica “Leitz” Trinovid 10×40, https://binocular.ch/leica-leitz-trinovid-10x40b/). The 7×35 was particularly compact and light for its wide viewing angle; the image had a warm tone due to the reflective prism coating made of aluminium. The Trinovid featured an internal focusing mechanism, but wasn’t fully waterproof. The simple but elegant shape of its body made it a design icon. In 2019, Leica brought out a new “Retro”-Trinovid line of binos with an almost identical design as the 1960s models, but modern optics (see separate post “Leica Trinovid 7×35 2019 (“Retrovid”), https://binocular.ch/leica-trinovid-7×35-2019-retrovid/)”.
