APS-C telephoto lens for digital mirrorless camera

Abstract

The invention discloses an APS-C telephoto lens for a digital mirrorless system camera. The APS-C telephoto 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 and a tenth lens from the object space, wherein the first lens is a spherical positive lens projected towards the object space, the second lens is a spherical positive lens projected towards the object space, the third lens is a spherical negative lens recessed towards the object space, the fourth lens is a spherical negative lens recessed towards the object space, the fifth lens is a spherical negative lens recessed towards the object space, the sixth lens is a spherical positive lens projected towards the object space, the seventh lens is a spherical positive lens projected towards the object space, the eighth lens is a spherical negative lens recessed towards the object space, the ninth lens is a spherical positive lens projected towards the object space, and the tenth lens is a spherical negative lens recessed towards the object space. The APS-C telephoto lens has the advantages that the large aperture design is adopted, the shutter speed is accelerated, and in addition, the cost performance is high.

Description

technical field [0001] The invention relates to a digital camera lens, in particular to a 35mm f0.95 APS-C frame lens for a digital micro-single camera with high imaging quality, high cost performance, light weight and high shutter speed. Background technique [0002] With the continuous development of science and technology, digital cameras are constantly developing towards the direction of light, thin, small and multi-functional. cost, and can effectively improve the applicability of the digital camera. However, in the lens of digital cameras, there is a gap in the production and design of domestic lenses, almost all of which are produced abroad. These lenses are expensive, costly, and cost-effective, which is a heavy burden for ordinary photographers. Contents of the invention [0003] In view of the above-mentioned shortcomings in the prior art, the purpose of the present invention is to provide a camera with high imaging quality, high cost performance, independent in...
