What this lens is good for
Bird and wildlife photography
A 200-800mm full-frame equivalent zoom with stabilisation and weather sealing, this is the accessible route to extreme reach for birds and distant wildlife. It is handholdable and far cheaper than the PRO super-telephotos, making it the practical choice for hobbyist wildlife shooters. Full guide →
Distant subjects and the Moon
The 800mm equivalent reach pulls in subjects far beyond what shorter lenses can capture, from perched birds to the Moon. The slow f/5-6.3 aperture means it works best in good light, and at 1,120g it is a substantial but manageable lens to carry.
Dual IS compatibility
This lens triggers Dual IS on compatible Panasonic bodies, combining lens OIS with body IBIS for improved stabilisation.
