Description — Olympus 100-400mm f/5-6.3 IS
The Olympus M.Zuiko Digital ED 100-400mm f/5-6.3 IS is a super-telephoto zoom lens designed for Micro Four Thirds mirrorless camera systems. With a focal length range spanning 100mm to 400mm and a maximum aperture of f/5, it provides substantial reach for subjects that demand distance — from wildlife in the field to athletes on the track. The lens features optical image stabilization, working to steady the image during handheld shooting, which is especially valuable at the longer end of the zoom range.
Both auto and manual focus modes are supported, giving photographers control over their focusing approach regardless of subject behavior. The 72mm filter thread accommodates standard circular filter accessories with ease. Weighing 1,120 grams, this is a serious telephoto tool that reflects the optical demands of its range.
Mounted via the Micro Four Thirds lens mount, it integrates directly with compatible MFT mirrorless bodies for a seamless shooting experience across the full focal length range.
