Fixed focus lens generally has the advantages of light weight, small volume, high optical imaging quality and low cost.
Compared with zoom lens, fixed-focus lens has only one focal length, so there are fewer lens groups in the lens, which greatly improves the chromatic aberration of fixed-focus lens.
Some special lenses can only be made into fixed-focus lenses because of design or cost reasons.
Super telescope or super wide-angle lens, shift lens, reflection lens, super aperture lens or macro lens can only be made with fixed focus lens.
The focal lengths of fixed-focus lenses manufactured by most lens manufacturers are as follows: 20mm, 24mm, 28mm, 35mm, 50mm, 85mm, 105mm, 135mm, 200mm, 300mm, 400mm and 600mm. Manufacturers will also design more than one lens with focal length ranging from 24 mm to 200 mm, and the maximum aperture value is different to meet the needs of different photographers.
Sony Quan Huafu's cheapest standard fixed-focus lens includes 1 aspheric lens, which can effectively suppress various forms of aberration. With circular aperture blades, the maximum aperture is F 1.8.

After a period of writing, I have accumulated some knowledge, but there are still many shortcomings. I am also trying to solve some feedback problems from readers, such as the problem that the name and classification of shots are not clear, which will lead to misleading, and the problem that the data is too theoretical for women to read.
In this article, I have considered the readers' great suggestions and optimized the number of words and language of the article on the premise of ensuring the quality. I wonder if you are satisfied?
