Panasonic's Mark II 100-300mm for MFT — 200-600mm equivalent with improved weather sealing and coatings.
The Panasonic 100-300mm f/4-5.6 II Power O.I.S. (2017) is the updated version of Panasonic's budget super-telephoto for MFT, delivering 200-600mm equivalent. The Mark II improved weather sealing, coatings, and dust resistance over the original.
600mm equivalent reach at modest weight. Power O.I.S. stabilisation. Soft at 300mm wide open — stop to f/8. Good for daylight wildlife and birding on MFT. 520g — MFT weight advantage at play.
Micro Four Thirds mount, 67mm filter thread. Dust/splash proof — Mark II improvement. Power O.I.S. 520g. 150cm minimum focus. Compatible with DMW-TC14 1.4x TC for 840mm equivalent.
Good used availability. Check O.I.S. mechanism. The Leica DG 100-400mm is sharper but costs more. For budget MFT telephoto reach, this Mark II remains a practical choice.
