Panasonic Leica DG 100400mm f/4-6.3

Telephoto super-powers for MFT

Like the Fujifilm 100-400mm lens, this is designed for crop-sensor cameras, but this time of the Micro Four Thirds variety. As such, the size of the image sensor enables a more lightweight construction, and a 2x focal length multiplier that boosts the effective zoom range to 200-800mm.

The Panasonic Leica DG Vario-Elmar 100-400mm f/4-6.3 Asph. Power O.I.S, to give this its full title, boasts Leica backing, aspherical elements and optical image stabilisation, which can work with the in-body stabilisers of various MFTs. The optical path includes two ED elements, one aspherical ED element and one Ultra ED element. A locking ring lets you lock the zoom ring at any position.

Performance

Autofocus is fast and accurate and image stabilisation works well, although it lacks a switchable panning mode. Optical performance is highly impressive all-round.
