Abstract

The invention discloses a compact 35mm F0.95 digital camera APS picture lens. The picture lens sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens, a tenth lens and an eleventh lens from an object side, wherein the first lens, the second lens, the sixth lens, the seventh lens, the ninth lens and the tenth lens are spherical surface positive lenses convex in the object side, the third lens is a spherical surface negative lens convex in the object side, the fourth lens and the eleventh lens are spherical surface negative lenses recessed in the object side, the fifth lens is a spherical surface positive lens parallel with the object side, the eighth lens is a spherical surface negative lens parallel with the object side, and a diaphragm is arranged between the third lens and the fourth lens. The compact 35mm F0.95 digital camera APS picture lens is advantaged in that the picture lens is a standard lens, an aperture is super large, exquisite appearance is realized, and cost performance is quite high.

Description

technical field [0001] The invention relates to a digital mirrorless camera lens, in particular to a digital mirrorless camera super large aperture APS frame lens with a specification of 35mm F0.95. Background technique [0002] There are many domestic photographers, and there is a huge demand for lenses. However, there is a gap in the production and design of domestic lenses, and foreign matching lenses are high in price and low in cost performance, causing a heavy economic burden on the majority of ordinary photographers. [0003] Therefore, developing a lens with high imaging quality and high cost performance has become an urgent problem to be solved. Contents of the invention [0004] In view of this, the object of the present invention is to provide a compact 35mmF0.95 digital camera APS format lens to solve the problems of low cost performance of existing lenses. [0005] The technical solution provided by the present invention is: a compact 35mmF0.95 digital camera...
