Abstract

The invention relates to a digital micro-single camera lens, and especially relates to an M-port digital micro-single camera super-large aperture full-width lens with effective focal length f being 50mm and relative aperture F being 0.95. The lens sequentially comprises a first lens (1), a second lens (2), a third lens (3), a fourth lens (4), a fifth lens (5), a sixth lens (6), a seventh lens (7),an eighth lens (8), a ninth lens (9), a tenth lens (10) and an eleventh lens (11) from an object side. The lenses all adopt spherical design to correct various aberrations, spherical aberrations generated by adopting spherical mirrors can also be avoided, the structure is simplified, and the imaging quality is improved. The lenses are all made of glass materials produced by the Chengdu Luminescent Photoelectric Co., Ltd., so that the quality of the lenses and the definition of the lens are improved, the use performance of the lens is improved, and the cost performance of the lens is greatly improved.

Description

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