Do Sony Lenses Have Adjustable Aperture?
Understanding the Basics of Aperture
Aperture, in photography, refers to the size of the opening in the lens that controls the amount of light that enters the camera. It is measured in f-stops, which are standardized to describe the lens’s ability to control light. The f-stop range is from f/1.4 (the smallest opening) to f/16 (the largest opening). A smaller f-stop value means a larger aperture opening, while a larger f-stop value means a smaller aperture opening.
Sony Lenses and Aperture
Sony, a well-known brand in the photography industry, offers a wide range of lenses for various camera models. When it comes to lenses with adjustable aperture, Sony offers a few options. However, the availability and functionality of these lenses can vary depending on the specific model and camera.

Some Sony E-mount lenses, such as the Sony FE 50mm f/1.4 ZA and Sony FE 85mm f/1.4 ZA, have an adjustable aperture. However, the aperture is not fully adjustable, and the lens’s aperture is fixed at f/1.4.
