Most of the binoculars on Minox’s offer are roof prism instruments. Among them you can find, though, two porroprismatic exceptions: a BD 8x44 BP and a BD 10x44 BP. The producer ensures that only a Porro construction can provide two important features. Firstly, the transmission of such a device is supposed to reach as much as 94.5% and secondly, when objective lenses are further apart the image is supposed to be 3-D in an exceptional way.

The Fomei Leader 8x56 DCF is one of the newest binoculars made by a Czech company which orders its products in Chinese and Japanese factories. The 8x56 DCF model is a cheap pair of binoculars produced in China. It sports Schmidt-Pechan roof prisms made of BaK-4 glass and it comes with a three-year-long guarantee.

The Swift Optics 828 HHS Audubon 8.5x44 binoculars is one of the most prominent products of the Swift company. The “HHS” acronym is a proof of it as it means nothing else than the initials of Humphrey H. Swift, the late managing director of Swift Instruments; the 8.5x44 model was also his last original design.

Bushnell Infinity is a relatively new series of binoculars, launched in 2007. These are roof system instruments, with the Schmidt-Pechan prisms, made of BaK-4 glass, phase correction coated with PC-3 and reflection SHR coatings.

The Japanese Tamron company’s optics specialists were specifically commissioned by the Swift company to design the first Swift Audubon binoculars. The design was based on the ornithological market research.

The Analytik Jena company, the manufacturer of Docter binoculars, is one of the most enigmatic companies on the binoculars market. When the news about the roof-prism Docter 8x58 B/CF was released at first it was difficult to find the device on the producer’s site.

The Victory T* FL series is the highest series of the Zeiss binoculars. It consists of roof prism models with the objective lenses’ diameters from 20 to 56 mm. The smallest devices have the Schmidt-Pechan prisms inside, the bigger – the Abbe- Koenig prisms.

The binoculars from the Meostar B1 series are the newest product in the Czech Meopta company’s line-up, launched at the beginning of 2005. This series consists of nine roof-prismatic models with the following parameters: 8x32, 10x32, 7x42, 8x42, 10x42, 7x50, 10x50, 12x50 and 8x56.

At the beginning of 2006 William Optics, a Taiwanese company, launched a 7x50 ED set of binoculars, equipped with one low-dispersion glass element objective lenses. The binoculars look like Fujinon FMTR-SX products, renowned for their excellent optical and mechanical quality. William Optics also announced expanding its offer by a 10x50 model and they did it in fact, immediately.

The Carl Zeiss Jena 10x50 binoculars had different names depending on the type of its focusing system. The Dekaris 10x50 model featured an individual focusing system and the Dekarem 10x50 – a central focusing system.

All binoculars from the Nobilem series are big and heavy, equipped with huge prisms. They consist of a two-element objective lens and a four-element eyepiece (you can conclude as much from a schematic drawing in its advertising leaflet). All air-to-glass surfaces are covered by high quality antireflection multilayer coatings.

All Fujinon FMTR-SX binoculars are equipped with huge Porro system prisms. Among others they meet military (US Army) requirements (Mil Spec) of endurance– they are shock-proof, according to the M24 specification, and sea waterproof.

As Ecotone aims its products mainly at ornithologists, small wonder the SR-4 model was produced with classic “birding” parameters of 10x42. We are also not surprised by the fact that the prisms are put in the roof system. Here the typicality of the Ecotone stops, though.

The legendary Carl Zeiss company doesn’t have to be introduced I suppose. Every amateur of good optics has heard about them and about their high-end binoculars series – Victory T* FL – which consists of roof prism models in a variety of configurations, including: 8x32, 10x32, 7x42, 8x42, 10x42, 8x56, 10x56 and 12x56.

In 2006 the 8x40 and 10x40 binoculars were added to the bunch od Carl Zeiss Conqests and about one year later – the 8x50 and 10x50 models. The Conquest line-up became even bigger when in 2009 next two instruments, with the parameters of 8x56 and 10x56, were launched as well.
