Panasonic's professional MFT telephoto zoom — 70-200mm equivalent at constant f/2.8 with Power OIS.
The Panasonic Lumix G X Vario 35-100mm f/2.8 Power O.I.S. was released approximately 2012 as a constant f/2.8 telephoto zoom for Micro Four Thirds, providing a 70-200mm full-frame equivalent range. Power O.I.S. motorised zoom is available. At 360g and 58mm filter thread it is lightweight for a constant f/2.8 telephoto zoom on MFT. Seven rounded aperture blades. 0.85m MFD.
The optical design uses 18 elements in 13 groups including 1 UED and 2 ED elements. Seven rounded aperture blades. The 58mm filter thread. At 360g the lens is lightweight. Minimum focus distance of 0.85m. Power O.I.S. optical stabilisation. Constant f/2.8 aperture. 70-200mm full-frame equivalent.
The 360g weight for a 70-200mm f/2.8 equivalent is the MFT system advantage: a 70-200mm f/2.8 equivalent on full-frame weighs 1,400-1,700g. The Power O.I.S. motorised zoom enables consistent zoom speed for video without physical hand contact with the barrel. On MFT bodies with Dual I.S.2, the lens OIS and body IBIS operate cooperatively for enhanced combined stabilisation.
On the used market the Panasonic G X Vario 35-100mm f/2.8 is affordable as a constant f/2.8 MFT telephoto zoom. Condition checks: Power OIS engagement, motorised zoom function, 58mm front element for marks, and zoom ring smoothness. Compatible with all Micro Four Thirds bodies from Panasonic, Olympus, and OM System.
