Vixen Geoma III ED Series Geoma III ED65 Fieldscope, ZOOM, 18108-7

High-performance field scope with ED lens. Includes smartphone adapter. ED (extra-low dispersion glass) lens provides a field of view with excellent contrast and minimal color fringing. The dual focus ring makes fine focusing easy. Includes a smartphone camera adapter. Enjoy easy photography with your smartphone. [High contrast and clear vision thanks to PFM5 Coating] The entire optical surface of the lens is coated with a five-layer anti-reflective multi-layer coating called PFM5 Coating (Perfect Fully Multi-Five Coating). This coating has less light loss than PFM Coating, which has three layers of multi-coating applied to the entire optical surface of the lens, resulting in a brighter field of view and superior contrast. [16-48x Zoom Lens (Parfocal)] This zoom lens allows for stepless magnification change from 16x to 48x. Its parfocal design means that the focal point remains almost constant even when the magnification is changed. Once you have focused, there is almost no need to refocus even when the magnification is changed, allowing you to concentrate on your observation. [Eyepieces designed for ease of viewing] The high eyepoint design (eye relief 20-18mm) allows you to see the entire field of view without having to press the eyepieces hard against your eyes. Furthermore, the large 24mm diameter eyepieces and twist-up eyepieces, which adjust the height by turning them with your fingers, are designed to reduce eye fatigue even during extended observations. You can see a wide field of view with your bare eyes, or even while wearing glasses. [Dual Focus Ring] The dual focus ring allows you to adjust the focus at two speeds: coarse and fine (reduction ratio 1:9). After quickly focusing with the coarse focus ring, you can precisely adjust the focus position with the fine focus ring. This makes precise focusing extremely smooth when observing details such as bird feathers or when taking photographs.
