Description: On most lenses, the manufacturers provide a focusing mechanism that extends only a few millimetres, partly to keep down costs and partly to restrict the lens to extensions for which its optics are optimised. To provide additional extension, one or more extension tubes can be added between the camera and the lens, to make the lens focus at closer distances and therefore produce higher magnification. Features: 🔎【Product Specifications】: This macro extension tube kit includes 3 extension tubes-9mm, 16mm, and 30mm adapters. The workmanship is excellent, and using this setting will not degrade the optical quality of the lens. 🔎【How to Use It Together】: This macro extension tube is used with a manual lens with an aperture dial. Auto lenses can only be used at their maximum aperture. 🔎【Additional Extensions】: To provide additional extension, one or more extension tubes can be added between the camera and the lens, to make the lens focus at closer distances and therefore produce higher magnification 🔎【About This Item】: Can maintain clarity and saturation, but does not retain the automatic diaphragm. There is no electronic connection between the body and the lens. When this expansion ring is used with DSLR/SLR, you should set the camera to "M" mode. 🔎【Risk-free Products】: We serve you based on the principle of customer first.
