A fixed focus lens is a lens with a fixed focal length, usually with a larger aperture and higher optical quality. So, how should you choose a fixed focus lens? What factors should you consider when choosing a fixed focus lens?
When choosing a fixed focus lens, the following factors need to be considered comprehensively:
Focal length
Focal length is one of the first considerations when choosing a fixed focus lens. Focal length determines the field of view of the lens, and fixed focus lenses of different focal lengths are suitable for shooting different scenes and themes. Common focal lengths include 50mm, 85mm, 35mm, etc.
Generally speaking, 50mm is the focal length closest to the human eye’s perspective, suitable for shooting portraits and daily life scenes; focal lengths of 85mm and above are suitable for telephoto portraits and portraits; focal lengths below 35mm are suitable for shooting wide-angle landscapes and environmental photos.

Aperture
The size of the aperture affects the amount of light entering the lens and its ability to control the depth of field.
Generally speaking, a fixed-focus lens with a larger aperture (such as F1.4, F1.8) can take clearer photos in low-light environments and produce a better background blur effect, which is suitable for portraits and close-up shots; a lens with a smaller aperture (such as F2.8, F4) is more stable in depth of field control and backlighting performance, and is suitable for shooting landscapes and buildings with a deep depth of field.
Lens quality
In addition to focusing on focal length and aperture, you also need to consider the quality of the lens when choosing a fixed-focus lens. The quality of the lens includes aspects such as lens glass quality, lens coating, and focus motor.
High-quality glass lenses and lens design can provide higher image quality and color reproduction, while suppressing the occurrence of optical phenomena such as lens dispersion.

Weight and volume
Fixed focus lenses are usually lighter than zoom lenses, but they also have a certain weight and volume. The weight of the lens will directly affect the user experience.
High-quality materials and moderate weight can improve the durability and portability of the lens. This can be determined based on your own usage habits and shooting needs.
Price
The price range of fixed-focus lenses is wide, from entry-level to professional level. The prices of lenses of different brands, models and specifications vary greatly, normally ranging from a few hundred to several thousand yuan. You need to choose the one that suits you according to your budget.
