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.

The 6.5×32 format itself is very rare, there are very few binoculars with such a formula. The reason for the rarity is that the close and more popular 7×35 format comes on the heels of these binoculars. A small magnification provides good image stability, and a large exit pupil provides a brighter image at dusk and at night than comparable 8×32 binoculars. I also briefly tested Levenhuk Karma 6.5×32 binoculars (in roof prism) – which in almost all parameters are worse than Levenhuk Sherman PRO 6.5×32 (except weight and dimensions). Of the similar binoculars, there are also БПЦШ 6×30, Kowa YF30-6 6×30, Kowa BDII32-6.5XD and Vixen SG 6.5×32, but I can’t say how they are in terms of picture quality.

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 plastic plug under which the thread under the tripod is hidden. The plug is bad – after one twisting and twisting, the plastic thread began to wear off. The focusing drum is ribbed, spinning tight, the full focusing range is about 300 degrees. Rotating it with one finger is uncomfortable, you also have to pull your finger. For those who need quick and responsive refocusing, binoculars are unlikely to work. The simultaneous use of the index and middle fingers can help a little, and on both hands – that is, the fingers on one hand “pull” the drum, and on the other hand they “push” it.

By the way, the binoculars are unstable on the lenses, and at the minimum values of the interpupillary distance they generally fall on the drum. This is not really a drawback, but you should be aware of it.

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 metall.

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.

Summary:
+ full coating
+ excellent distortion correction
+ good image quality in most of the field of view
+ bright image
+ good color rendering
+ wide field of view
+ long eye relief
+ BaK-4 prism
+ excellent collimation
+ comfortable shape
+ metal bridge

– strong glare from internal surfaces
– blurred edge of the field of view
– “rolling ball” effect. Personally, it does not bother me, but there are people who are intolerant to this effect.
– tight focus and uncomfortable drum
– slight yellowness
– small diopter adjustment range for people with myopia (maximum up to +2.5)
–plastic thread plug.

Despite some disadvantages, I liked the Levenhuk Sherman Pro 6.5×32 binoculars – in terms of price / quality ratio it is very good, especially in the rare 6.5×32 format. 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.
P.S. Two years after writing the review, I still bought myself such a pair of binoculars.
