Cách đạt được độ phóng đại 100 lần với tiêu cự 300mm

The silver part of our company’s long-distance lens (rear converter) is removed.



It’s a long-distance lens with a magnification ranging from 4x to 40x when the focal length is 300mm.
※ Magnification is calculated based on a 1/2.5 inch camera, equivalent to a 17-inch monitor.

A 5x rear converter is attached.



However, attaching a 5x rear converter will decrease both brightness and resolution.

Our long-distance lens is equipped with a focusing adjustment function, so you can use it with focal lengths ranging from 200mm to 400mm. When attaching the 5x rear converter, if the focal length is set to 200mm, the magnification will be approximately 150x.
