Panasonic Lumix G Vario 100-300mm f/4-5.6 Mega O.I.S. - Micro Four Thirds Mount

The Panasonic Lumix G Vario 100-300mm f/4-5.6 Mega O.I.S. is a long-reach telephoto zoom offering a 200-600mm equivalent focal length in a relatively portable form factor. It is a popular choice for budget-conscious wildlife and sports photographers using the Micro Four Thirds system. The lens incorporates Mega O.I.S. to assist with handheld shooting at long focal lengths and one extra-low dispersion element to reduce chromatic aberrations. The autofocus is driven by a linear motor for responsive tracking of moving subjects. On the used market, 'zoom creep' can occur on well-used units, so the tension of the zoom ring should be assessed. SDS checks for optical alignment, ensuring the lens is sharp at the 300mm end where performance can sometimes tail off if the lens has suffered a knock. The O.I.S. switch and focus limiter should operate firmly. We also inspect the deep lens hood and filter thread for signs of impact, and ensure the glass is free from fungal growth or heavy internal dust.
