Panasonic/Leica's MFT super-telephoto covering 200-800mm equivalent with dual OIS — a wildlife favourite.
The Leica DG Vario-Elmar 100-400mm f/4-6.3 ASPH. Power O.I.S. II is the second-generation Panasonic/Leica DG super-telephoto zoom for Micro Four Thirds, providing a 200-800mm full-frame equivalent range. The 'Leica DG' designation indicates Panasonic-engineered optics with Leica quality certification. At 985g and 72mm filter thread it is the standard professional MFT super-telephoto zoom. Compatible with Dual IS on select Panasonic bodies for enhanced combined stabilisation.
The optical design uses 20 elements in 13 groups. Nine aperture blades. The 72mm filter thread is standard. At 985g the lens is moderate for an 800mm-equivalent zoom. Minimum focus distance of 1.3m. Power O.I.S. provides handheld stability. Variable aperture from f/4 at 100mm to f/6.3 at 400mm. Weather sealing. Compatible with Dual IS on select Panasonic bodies.
The 200-800mm equivalent on MFT covers wildlife, aviation, and sports at long distances rarely accessible without dedicated primes. At f/6.3 at 400mm, adequate ambient light is required — Power O.I.S. extends handheld range. The Leica DG certification indicates Panasonic's premium optical quality tier. The II version provides updated weather sealing and optical corrections over the original 100-400mm.
On the used market the Leica DG 100-400mm II is available at mid-range MFT super-telephoto pricing. Condition checks: Power O.I.S. engagement, zoom ring smoothness, and 72mm front element for marks. Confirm this is the II version with weather sealing. Dual IS coordination available with compatible Panasonic bodies.
