Panasonic's first-generation MFT telephoto zoom with Mega O.I.S. stabilisation.
The Panasonic Lumix G Vario 45-200mm f/4-5.6 Mega O.I.S. is a telephoto zoom for Micro Four Thirds, launched in 2007 as one of the earliest MFT lenses. Covering a 90-400mm equivalent range, it provides impressive reach in a compact package. It was one of the lenses that demonstrated the MFT system's telephoto potential.
Optical quality is reasonable for a consumer telephoto with decent centre sharpness at shorter focal lengths but noticeable softness at 200mm. Mega O.I.S. provides built-in stabilisation which is useful on Panasonic bodies that lack IBIS. On Olympus bodies with IBIS the lens stabilisation can be used in combination for improved results.
Micro Four Thirds mount only, 52mm filter thread. A Mark II version was released with improved optics and Power O.I.S. instead of Mega O.I.S. The original is identified by the silver Mega O.I.S. label on the barrel. The Olympus 40-150mm f/4-5.6 R is a cheaper alternative without built-in stabilisation.
Very affordable used. Check the O.I.S. switch and verify stabilisation engages when activated. Test autofocus at both ends of the zoom range. Dust inside the lens is common on older copies but rarely affects image quality. The Mark II version is worth the small premium for improved optics.
