Panasonic/Leica's MFT super-telephoto — 200-800mm equiv Mark I with Power OIS. See ID 515 for Mark II.
The Leica DG Vario-Elmar 100-400mm f/4-6.3 ASPH. Power O.I.S. is the Mark I version of the super-telephoto zoom for Micro Four Thirds. Covering 200-800mm equivalent, it provides extraordinary reach in a relatively compact package thanks to the MFT 2x crop factor.
Optically good for the range — sharp in the centre with the Power O.I.S. providing essential stabilisation at these extreme focal lengths. The variable f/4-6.3 aperture requires good light at 400mm. Autofocus is adequate but can slow at maximum telephoto.
Micro Four Thirds mount with 72mm filter thread. Approximately 985g. Weather-sealed construction. 1.4x teleconverter compatible for 280-560mm (560-1120mm equiv). Minimum focus distance 130cm. Focus limiter switch.
Available used at mid-range to professional prices. The Mark II updated stabilisation and coatings — see ID 515. The MFT 2x crop makes this an exceptional reach-to-weight ratio. Check for dust ingress despite weather sealing. Outstanding for wildlife and bird photography on MFT.
