Abstract

The invention provides an optical lens for long-distance shooting. The optical lens sequentially comprises a first lens with positive focal power, a second lens with negative focal power, a third lens with positive focal power, a fourth lens with positive focal power and a fifth lens with positive focal power from an object side to an image side. The optical lens for long-distance shooting can be applied to long-distance shooting equipment such as a telephoto lens and a telephoto lens, is large in view field angle, and effectively corrects various aberrations, so that good imaging quality can still be ensured at a relatively long shooting distance.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to an optical lens for long-distance shooting. Background technique [0002] With the development of science and technology, long-distance shooting devices have gradually emerged. The optical system photosensitive elements of long-distance shooting equipment are nothing more than photosensitive coupling elements or complementary metal oxide semiconductor elements. With the improvement of semiconductor process technology, the photosensitive elements Pixel size shrinks, and optical systems tend to have higher pixels and higher image quality. The optical lenses of the prior art generally have defects such as poor imaging quality and small field of view. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention provides an optical lens for long-distance shooting, which can be applied to long-distance shooting equipment such as telephoto lenses and ...
