The Fujinon KF 8x32W binoculars came to my test. 8×32 format binoculars are considered the most versatile in combination of magnification / dimensions / weight parameters, suitable for daytime and astronomical observations. For ground objects at dusk, 8×32, of course, will be noticeably dimmer than 8×42 or 8×56, however, for long-term wear on the neck 8×32 will be more convenient. This is especially true for hunters, animal watchers and tourists.

I was very surprised that the Fujinon KF 8x32W has very few reviews. As it turned out, there are models that are very similar in characteristics and appearance to it – Sightron “Blue Sky” II 8×32, Kenko Ultra View EX OP 8×32 DH II, Vixen New Foresta HR 8×32 WP. Their case looks a little different, and also, most likely, a different coating, but there is a very high probability that optically they MAY BE similar to Fujinon KF 8x32W, and he himself is the “reincarnation” of the above binoculars.

Binoculars with a magnification of 10x, in my opinion, are the ultimate for handheld observation. Magnification over 10x already require an support, tripod or built-in image stabilizer. Binoculars of the 10×42 format are in stable demand, they are noticeably lighter and more compact than binoculars 10×50, but they have a greater magnification than similar ones in weight and dimensions of 8×42. However, making a good roof binocular is not an easy task. My attention was drawn to one of the top Olympus binoculars – 10×42 EXWP I. The binoculars were released a long time ago – the mentions I found go back to 2003. I was unable to find a press release on the release of this binoculars on the Olympus website.

Many of the Olympus models present in stores have been available since 2003 (for example, the Olympus 7×35 DPS I). In 2018, the new Olympus 8×42 Pro and 10×42 Pro binoculars with ED glass, dielectric coating, and improved illumination were presented.

Recently, the Visionking 5×25 wide-angle binoculars came to my test. With a magnification of only 5x, he has a field of view of as much as 15.8 degrees. I looked at this binoculars for a long time, but everything was overcome by doubt. A binocular with such characteristics cannot also be inexpensive – there is always some catch, especially if it is a binocular with roof prisms. Well, it turned out that way, but more on that later. In the meantime, I propose to get acquainted with the miracle of the Chinese optical industry.
