Constant f/1.8 aperture

The lens’s standout feature is its constant maximum aperture of f/1.8 across the entire zoom range. This ensures comfortable shooting even in low light without excessively boosting ISO, and also allows you to create expressive bokeh. A 11‑blade aperture is responsible for soft, beautiful background blur.

Wide compatibility

The lens is offered for popular mirrorless systems: Sony E, Fujifilm X, Leica SL, and Canon RF-S. All versions except the Canon one come with an aperture ring featuring a click switch. On the Canon version, this ring can be reassigned via the camera menu.

Internal zoom and focusing

Autofocus is driven by a fast HLA linear motor. The lens design provides internal focusing and internal zoom, with noticeable focus breathing minimized. Despite its impressive specs, the model remains relatively light — it weighs just over 500 grams.
