200-800mm equivalent super-telephoto zoom built for MFT mirrorless
The OM System M.Zuiko 100-400mm f/5-6.3 IS II delivers a 200-800mm full-frame equivalent range in a package that fits in a serious hiking pack than a rolling luggage cart. On Micro Four Thirds bodies, that 2x crop factor turns this into genuine big-glass territory without the weight penalty of a full-frame super-telephoto setup. The IS II generation brings upgraded stabilization over its predecessor, which matters at 400mm where even a slight tremor shows up in the frame. Weather sealing keeps the lens functional in rain and dust, which is exactly the kind of condition wildlife and outdoor sports shooters regularly work in.
The MSC (Movie and Still Compatible) autofocus system is tuned for both fast-moving subjects and video pulls, running quiet and tracking with the responsiveness MFT shooters expect from a native-mount lens. A 72mm filter thread gives you a workable front element for polarizers and ND filters. At the long end, this lens reaches focal lengths that most photographers never touch with a single-lens kit, making it a serious tool for subject-to-camera distances that would otherwise require fixed super-telephoto primes costing several times as much.
Who It's For
Wildlife photographers working from blinds or on foot will find the 200-800mm equivalent range covers everything from mid-distance bird perches to tight animal portraits without swapping glass. Sports shooters at outdoor events get a lens that holds up in wet conditions thanks to the weather sealing, while the MSC AF tracks athletes at speed. Travel photographers who prioritize reach over maximum aperture can cover safari-style distances without checking a second bag. Video shooters on MFT bodies benefit from the quiet AF drive and image stabilization when pulling focus during handheld wildlife sequences.

FAQ
- What's the real-world focal length on MFT bodies like the OM-1 or E-M1 Mark III?
- 200-800mm equivalent due to the 2x crop factor, which puts you in serious telephoto territory without carrying a full-frame super-telephoto prime.
- How does the IS II stabilization compare to the original M.Zuiko 100-400mm?
- The IS II generation brings upgraded stabilization specifically designed to handle the shake that appears at 400mm, making handheld shooting more practical at the long end.
- Is this lens weather sealed for outdoor use?
- Yes. It has enhanced weather sealing that keeps it functional in rain and dust, which matters when you're shooting wildlife or sports in unpredictable conditions.
- What autofocus system does this lens use?
- MSC (Movie and Still Compatible) autofocus, which runs quiet and tracks responsive subjects for both stills and video work.
- What filter size does the 100-400mm use?
- 72mm thread, which is workable for polarizers and ND filters without needing step-up rings.
- How does the aperture perform across the zoom range?
- Starts at f/5 at 100mm and falls to f/6.3 by 400mm, which is standard for this class of super-telephoto zoom and reflects the optical trade-offs required for the reach.
- Is this lens compact enough for travel?
- For a 200-800mm equivalent super-telephoto, yes. The MFT mount and native lens design keep it substantially lighter and smaller than equivalent full-frame super-telephoto setups.
