Does Longteng 18-300 still need a fixed focus lens?

Longteng 18-300 is a portable zoom lens, which is suitable for shooting various scenes and themes. Due to the complexity of its design and the limitation of its optical structure, its imaging quality is affected to some extent. The fixed-focus lens has a simpler optical structure and can focus on providing higher optical performance and better image quality. The fixed-focus lens has a larger aperture, which can take better photos in low light and produce better background blur effect. Fixed-focus lenses can also provide higher resolution, less distortion and chromatic aberration, better contrast and detail.
