Aperture
The Carl Zeiss Distagon T 3,518 features a maximum aperture of F3.5 and can be stopped down to a minimum aperture of F22.

Given the wider 18mm field of view, the background will naturally stay a bit more in focus, making it ideal for environmental portraits, street photography, or landscapes where context matters. The minimum setting of F22 is excellent for deep depth of field work like macro photography, though you may want to avoid the absolute smallest settings to skip the sharpness loss caused by optical diffraction.
