The aperture of the lens can be♣ divided into continuous aperture and discontin☆uous aperture. The continuous iris can be adjαusted steplessly, and it can be adjusted at any ©position between the two stop iris. The discontinuous aperture can be adj≈usted according to the first, o♠ne-half, or one-third of the aperture, and there is a clear positi oning feel when adjusting. Some brands of autofocus→ lenses do not have an aperture adjustment r•ing, and are adjusted by the camera's aperture adjustment mechanism, s♦uch as Canon's ef series ♣lenses and Nikon's af g series lenses.

When adjusting the iris, the iris is always at the maximum ©aperture. Only when the shutter button is pres×sed to release the shutter, the aperture automatically shr inks to the set f-factor, and the apertu€re returns to the ma♠ximum aperture after the exposure is completed.
