Olympus M.Zuiko Digital ED 100-400mm f/5-6.3 IS - Micro Four Thirds Mount

The Olympus M.Zuiko 100-400mm f/5-6.3 IS is a high-performance telephoto zoom lens providing a 200-800mm equivalent focal range. It features built-in optical image stabilisation that works alongside the camera's internal stabilisation, though it does not support Sync IS. The lens is weather-sealed and compatible with the MC-14 and MC-20 teleconverters, extending the reach up to 1600mm equivalent. It is a popular choice for wildlife and bird photography due to its relatively lightweight design for such a long reach. Examine the lens for any signs of heavy impact, particularly around the filter thread and tripod collar. The zoom ring should operate smoothly without sticking. SDS checks the internal optical stabilisation for quiet operation and ensures the autofocus motor is responsive throughout the zoom range. We also inspect the weather seals and the rear mount for signs of excessive wear from teleconverter use.
