The following test shows clearly that the Levenhuk Sherman Pro binoculars are in the same category as the Nikons Action EX device, one of the most often recommended low cost binoculars with a price tag below 200 Euros. It seems that the Levenhuk are actually closer to the performance of the Nikons one decade ago, when their price was two times higher and they came with all air-to-glass surfaces covered by antireflection coatings. The transmission graph below shows those coatings are exactly the main difference between the Shermans Pro and contemporary Action EX devices.
Levenhuk used simple multilayer coatings which provide characteristic green reflections from the elements and a distinct transmission decrease in the centre of the visible spectrum. Still they covered all air-to-glass surfaces, reaching as a result a very sensible transmission level: for the red colour, it is able to get to 90% and for blue it is high enough to offer a very good colour rendition. If you remind yourself of the transmission of the Nikona Action EX 8x40 CF in the middle of the visible spectrum, which amounted to barely 80%, and a very noticeable decrease for blue, the advantage of the Levenhuk becomes evident.
The tested binoculars didn’t avoid slip-ups because at this price point it would be very difficult to do so. One of them is rather funny. The producer stinted on glue so much that the rubber amour of the objective tubes doesn’t simply stick up. It is completely removable. I suppose the real price of the binoculars should be augmented by the cost of a tube of glue.
There’s another advantage of the Levenhuk binoculars. There are not many Porro devices with a good price/quality ratio in the 32 mm class of objective lenses. It should be emphasized, however, that the Sherman Pro series is a bit more expensive than the Nikon Action EX. On the one hand it is perfectly understandable as the binoculars are also a tad better. On the other hand, though, the Nikon brand name binoculars are far more recognizable on the market; overall a slight lowering of the price would be very good for the Levenhuk and might increase the interest among potential customers. However, even with the current price tag, the tested pair of binoculars is so good that I would recommend it to beginners without scruple.
