Principle of laser sky lens

The principle of laser lens is realized by a dry plate, which is a Quan Huafu lens.

Quan Huafu is a photographic term, which means that the photosensitive area is 36×24? Mm size specification, used to describe the imaging circle index of the lens and the size of the photosensitive element.

Quan Huafu lens refers to the lens that can be installed on Quan Huafu SLR camera and APS-C SLR camera, while APS-C lens can only be installed on APS-C SLR camera. Generally, Quan Huafu lens is not marked, and APS-C lens is marked on the model.

In addition, with Quan Huafu's strong market share, Sony released the FE? 24-240mm？ F3.5-6.3？ OSS is not only the first zoom lens in Quan Huafu, but also the first lens with a zoom ratio of 10 and a wide angle of 24 mm Although the image quality of this lens can only be described as sparse and ordinary, it has made a great breakthrough in specifications. After that, Canon and Nikon followed Sony's footsteps and launched RF? 24-240mm and z? 24-200mm can also show that it is quite wise to raise the wide-angle end to 24 mm
