Its seesaw-type focus adjustment mechanism assures easy focusing operation by the holding hand, allowing the user to observe a subject with one hand while trekking or hiking, or while carrying a bag with another hand. 2. Bright, clear view All reflective surfaces of the optical elements and prisms are fully multi-coated to prevent excessive reflection. Coupled with phase coating applied to the roof prism, this model boosts transmissivity and delivers outstanding imaging performance with a bright, sharp, high-contrast view of the subject with minimal flare and ghost images. 3.Dedicated accessories that greatly expand the use Using the monocular with the smartphone adapter ""V-SA1""* will allow the user to observe a spectacular, magnified view of the subject on the phone's screen and to save the images directly to the device. Also, by mounting a macro stand ""V-MS1"", it can be used as a microscope with approximately 18 times magnification to observe an enlarged view of microscopic objects. When the object is dark due to the monocular shadow during observation, you can observe it while illuminating it with the built-in LED light. In addition, using it with ""V-SA1"" can significantly expand the range of use of the main unit, including the ability to shoot and save super close-up images. *Depending on your smartphone's size and the position of the camera lens, you may not be able to attach it. 4.
