Levenhuk provided me with interesting binoculars for testing – Levenhuk Sherman Pro 6.5×32. Due to its small magnification and wide field of view (almost 10 degrees), such binoculars can be useful for studying the constellations, for observing landscapes, and also where a stable picture is required with minimal shaking (e.g. sporting events). Declared wide-angle five-lens eyepieces with corrected distortion, fully coating of optical elements, Bak4 prisms, long eye relief and much more.

Levenhuk Sherman Pro 6.5×32 binoculars come in a colorful cardboard box, including binoculars, a bag with a shoulder strap, a neck strap with a neoprene insert, lens caps and eyepieces, a cloth for wiping optics. Made binoculars in China.
The binoculars are quite heavy, the measured weight with covers was 780 grams. The approximate dimensions are 12.5 x 17 x 6.5 cm. The case is externally covered with rough rubber. Holding binoculars is quite convenient and pleasant. In the front there is a plug under which the thread under the tripod is hidden. The focusing drum is ribbed, spinning tight, the full focusing range is about 300 degrees.
The diameter of the lens is exactly 32 mm. Lenses have blue and green coating. It is noticeable that at the very edge of the lens a lilac reflection. The prisms have a green coating. A close inspection with a flashlight showed that all optical surfaces are coated. The edges of the lenses without blackening.
Eye lenses are large, diameter 25 mm, with green and blue coating. The eye relief is about 20 mm, can be observed with glasses. The measured field of view of the eyepieces is 60 degrees. There is a diopter correction lever on the right eyepiece. The eyepiece bridge is plastic, it bends a little when pressed – I do not recommend strongly pressing your eyes to the eyecups.
The eyecups are huge, made of hard rubber. The eyecups have 4 positions with fixation.
Inspection of the gap showed that the binoculars add a yellowness to the image.
The exit pupils are round. When viewed from the eyepiece, glare surfaces are visible.

Despite some disadvantages, I liked the Levenhuk Sherman Pro 6.5×32 binoculars – in terms of price / quality ratio it is very good. I plan to take myself such binoculars for the collection. I recommend to buy if you need binoculars with a small magnification, a bright picture and a large field of view.
