Abstract

The invention relates to a lens for a digital mirrorless camera, specifically a full-frame lens with an M-mount digital mirrorless camera with an effective focal length of f=50mm and a relative aperture of F=0.95. The first lens (1 ), second lens (2), third lens (3), fourth lens (4), fifth lens (5), sixth lens (6), seventh lens (7), eighth lens (8) , the ninth lens (9), the tenth lens (10) and the eleventh lens (11), the lenses are all designed with a spherical surface to correct various aberrations, and can also avoid spherical aberrations caused by the use of spherical mirrors , simplify the structure and improve the imaging quality. The lenses are all made of glass produced by Chengdu Guangming Optoelectronics Co., Ltd., which improves the quality of the lens itself, the clarity of the lens, improves the performance of the lens, and greatly improves the cost performance of the lens.

Description

technical field [0001] The invention relates to a digital micro-single camera lens, in particular to an M-mount digital micro-single camera lens with an effective focal length of f=50mm and a relative aperture of F=0.95. Background technique [0002] In digital camera equipment, the production design of domestic lenses is insufficient. However, there are many photography enthusiasts in China and the demand is great. In the existing lens design, the 50mmF0.95M lens produced by the original Leica factory is expensive, causing a heavy economic burden to the majority of photography enthusiasts. Therefore, camera enthusiasts urgently need a lens with high imaging quality, cost-effective and simple structure to meet the needs of photography. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned shortcomings in the prior art, the purpose of the present invention is to provide an effective specification that corrects various aberrations, simplifies the structure, impr...
