Abstract

Our company invented a full-frame macro lens for digital cameras with a specification of 1-5x zoom, which includes the first lens, the second lens, the third lens, the fourth lens, the fifth lens, and the sixth lens in order from the object side. Lens, seventh lens, eighth lens, ninth lens, tenth lens, eleventh lens, twelfth lens. The first lens to the twelfth lens are all glass materials produced by Chengdu Guangming Optoelectronics Co., Ltd. The advantage of this 1‑5x zoom digital camera full-frame macro lens is that the lenses are designed with spherical surfaces to correct various aberrations, and can also avoid spherical aberrations caused by the use of spherical mirrors, simplifying the structure and improving Imaging quality, increase the shooting distance. The lens is all made of glass, which improves the quality of the lens itself and the clarity of the lens, and improves the performance of the lens.

Description

technical field [0001] The invention relates to a digital camera macro lens, specifically a digital camera full-frame macro lens, which is characterized in that it has an ultra-long object distance and creates superior conditions for photography and lighting. Background technique [0002] Among the macro lenses, the vast majority of lenses cause a lot of inconvenience to shooting and lighting due to the short working distance. Many photographers hope to have a macro lens with a long shooting distance and convenient lighting. This macro lens just solves this problem. Problems, and the cost performance is extremely high, which reduces the great economic burden for the majority of ordinary photographers. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a full-frame macro lens for digital cameras that corrects various aberrations, simplifies the structure, improves imaging quality, increases the working distanc...
