What this lens is good for
Travel portraits
An 85mm full-frame equivalent at f/1.7 in a tiny 130g body, with OIS, makes this an easy portrait lens to carry. It is the affordable, lightweight alternative to the Nocticron, keeping the same flattering focal length and adding stabilisation for handheld shooting. Full guide →
Everyday subject separation
The fast aperture and short telephoto reach are useful for everyday subjects, from people to pets to details, where you want a blurred background. The built-in OIS helps in low light and coordinates with Panasonic Dual IS bodies for extra steadiness.
Dual IS compatibility
This lens triggers Dual IS on compatible Panasonic bodies, combining lens OIS with body IBIS for improved stabilisation.
