Material : aluminum alloy MaxFocalLength : 10 millimeters MinFocalLength : 10 millimeters ModelNumber : S101715 PartNumber : 101715 ProductDescription : SWEBO 4th generation lens scope converter makes the camera lens instantly become a high-end telescope. Can be combined into a telescope or a microscope The focal length of the converter is 10 mm. The multiple after combinationis equal to lens focal length divided by 10. For example, the magnificationof combined telescope of 70-200mm lens will be 7-20 continuous zoom. Non-loss optical path design resultsin a compact volume. For example, the Canon port isonly 55x65 mm. It can replace the lens cover without affecting your camera bag configuration.It is installed at separated lens and able to conductremote observation at any time. Prism system for forming erect images first adopt total reflection optical design. Compared with the previous roofprism structure, it canpresent the good picture quality ofcamera lens by 100%. The eyepiece can be focused precisely,and the focusing is tight and smooth with comfortable hand feeling. It can notonly conduct precise focusing together with the lens focusing ring, but alsoexpand the scope of co-focusing, compatible with morelenses, and capable of the microscopic observation. All of the optical structuresare made of high-grade optical glass, with full-face MC wide band multilayer ARcoating. It can be manually focused only after the AF/MF switch is placed at MF for somelens. It is strictly prohibited to directly watch the sun Focallength: 10mm Lens:7 pieces (3 groups) Fieldof view:about 55 degrees Mechanicalstructure: all-metal precision machining Opticalstructure: high-grade optical glass Volume: 55x65 mm Weight:145g ProductSiteLaunchDate : 2020-02-03T03:31:06.460Z Size : Size 1 SkillLevel : Professional VideoCaptureResolution : 1080p WirelessCommunicationTechnology : Wi-Fi ZoomType : Fixed
