Founded in 1919, the Japanese brand Olympus has made great achievements in the field of optics and imaging, starting with the production of microscopes, and taking the lead in developing medical endoscopes in the 50s of the last century. In addition, its first half-frame rangefinder camera PEN has been sought after by many photography enthusiasts due to its lightness and portability, and the brand share of mirrorless cameras surpassed that of Canon and Sony in 2016. With the rise of smartphones and the cooling of the digital camera market, Olympus is gradually returning its business focus to the field of medical imaging.
 
In recent years, Olympus has applied its advanced experience in optical technology to the research and development of telescope equipment, and officially introduced the Pro series of telescopes to the Chinese market in October 2018. In the test of spectral transmittance, although the Pro series uses full-coverage multi-coating technology to improve the light intake surface of the prism and lens, control the loss of light energy, and ensure that the transmittance reaches 94% in the wavelength range (450 to 650nm) that can be felt by the human eye, there is still a gap compared with the high transmittance of 99.5% of Swarovski, the "pinnacle of the industry", and the color reproduction is not extreme enough.
 
In terms of other optical performance and handling, the Pro series also excels. First of all, the series has chosen the pleasing aperture specification of 42mm, which can achieve a good balance between the amount of light and the weight of the body compared to other calibers, and is suitable for a variety of environments, including low light. Second, it has a minimum focusing distance of 1.5 meters, which is half that of previous models, making it more effective for observing close objects such as insects and flowers. In addition, the simple design of the adjustable eye mask and the flip-down lens cover also improves the viewing experience for users.
 
Not only that, Olympus also launched several 100-yuan entry-level models in the early years, including the small-bore, lightweight Trip light RC II and DPC I, PCI., and the standard models DPS I AND EXPS I, with 8 models to choose from, with prices ranging from 280 to 950 yuan. Among them, the 10×25 PC I is more worth buying, ranking second with a score of 67 on the well-known review website Which, and winning the Best Buy title with Nikon Travelite EX.
 
It should be noted that the Olympus binoculars sold on domestic e-commerce platforms have a limited series of models, mainly Pro series and DPS I Paul mirrors. If you want to buy small models such as Trip light RC II, DPC I, PCI., etc., you need to buy them through the official website or overseas shopping.
