Abstract

The invention discloses a full-width camera lens of a digital camera. The full-width camera lens of the digital camera comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens sequentially from an object side, wherein the first lens is a spherical positive lens protruding towards the object side, the second lens is a spherical positive lens protruding towards the object side, the third lens is a spherical negative lens sinking towards the object side, the fourth lens is a spherical negative lens sinking towards the object side, the fifth lens is a spherical positive lens protruding towards the object side, the sixth lens is a spherical negative lens sinking towards the object side, and the seventh lens is a spherical positive lens protruding towards the object side. The full-width camera lens of the digital camera has a big field angle, a delicate appearance, and high cost performance.

Description

technical field [0001] The invention relates to a digital camera lens, specifically a digital camera full-frame lens with a specification of 35mm f2.0. Background technique [0002] In digital camera equipment, there is a gap in the production design of domestic lenses. None of them have independent intellectual property rights. However, there are many fans in China and the demand is great. Among the existing lens designs, there are 35mm f2.0 produced by manufacturers such as Nikon and Canon Pentax. The price is high and the cost performance is low, which is a heavy burden for the majority of 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 full-frame digital camera with a specification of 35mmf2. lens. [0004] The technical solution for realizing the present invention is: a digital camera full-frame lens with a specification of 35mmf2.0, which...
