What this lens is good for
Wildlife and sports
A 100-400mm full-frame equivalent at constant f/2.8 with built-in stabilisation, this is the longest-reaching f/2.8 zoom in the system. The bright constant aperture and reach suit wildlife, birds, and sports in lower light than slower super-telephotos can handle, with teleconverter support for even more range. Full guide →
Professional telephoto
The combination of f/2.8, 400mm equivalent reach, sealing, and in-lens stabilisation makes it a professional-grade telephoto for those who need brightness and reach in one lens. It is large and expensive, the trade-off for keeping f/2.8 across the range.
Dual IS compatibility
This lens triggers Dual IS on compatible Panasonic bodies, combining lens OIS with body IBIS for improved stabilisation.
