It is ideal for portrait and product photography, travel and video recording when you want to cover a range of focal lengths with a single lens. Discover our other lenses for mirrorless cameras.

Brightness across the entire zoom range

The fixed f/2.8 aperture maintains the same light intensity when zooming and makes it easier to take photographs in low light. The telephoto perspective and large aperture isolate the subject from a soft background, whilst perspective compression gives product shots a calm, controlled look.

Smooth focusing for video too

The HLA linear motor focuses quickly and smoothly in both stills and video. Focus breathing is minimised, so the composition remains unchanged when shifting the focus.

Main features
