What this lens is good for
Professional wildlife and birds
The system’s flagship super-telephoto, a 300-800mm full-frame equivalent at constant f/4.5 with a built-in 1.25x teleconverter that extends it to 1000mm equivalent without any glass change. The bright constant aperture, sealing, and stabilisation make it the top choice for serious birds and wildlife. Full guide →
Extreme reach with teleconverters
On top of the built-in TC, it accepts the MC-14 and MC-20 for extraordinary reach, well beyond 1000mm equivalent, while keeping autofocus and stabilisation. At 3,575g it is a tripod or monopod lens in most situations, a professional tool at a professional price.
Dual IS compatibility
This lens triggers Dual IS on compatible Panasonic bodies, combining lens OIS with body IBIS for improved stabilisation.
