Olympus 40-150mm f/4-5.6 ED MSC M.Zuiko Autofocus Lens for MFT (Micro Four Thirds), Black {58}

40-150mm MFT telephoto zoom with MSC autofocus and ED glass

The Olympus M.Zuiko Digital ED 40-150mm f/4-5.6 covers an 80-300mm equivalent focal range on Micro Four Thirds bodies, giving you genuine reach without the bulk that comes with full-frame telephoto glass. The ED (Extra-low Dispersion) glass element controls chromatic aberration across the zoom range, keeping fringing in check at the longer end where it typically becomes most visible. The 58mm filter thread is a practical size, compatible with a wide range of ND and polarizing filters.

The MSC (Movie and Still Compatible) autofocus mechanism is the standout feature here. MSC was built to minimize focus motor noise during video recording while maintaining the speed needed for still shooting. That means you get a single lens that handles both disciplines without the buzzing, grinding AF sounds that older screw-drive systems produce on camera. For a Micro Four Thirds kit, this lens fills the telephoto slot efficiently and travels light.

Who It's For

Travel photographers who want genuine telephoto reach without adding significant weight to their kit will find the 80-300mm equivalent range covers wildlife encounters, compressed street scenes, and distant landmarks. Video shooters using MFT bodies benefit directly from the MSC mechanism, which keeps autofocus tracking quiet enough for on-camera audio. Bird and nature photographers working closer subjects get the reach of 150mm with the inherent depth-of-field characteristics of the MFT format. Anyone building a compact two-lens MFT kit will find this pairs naturally with a standard zoom to cover most shooting situations.

FAQ

What's the actual focal length equivalent on my Micro Four Thirds body?

The 40-150mm focal length translates to an 80-300mm equivalent on MFT's 2x crop factor, giving you solid telephoto reach without carrying a full-frame lens.

How does MSC autofocus differ from older Olympus AF systems?

MSC (Movie & Still Compatible) minimizes motor noise during video recording while maintaining fast focus for stills, eliminating the grinding sounds from older screw-drive mechanisms.

Will this lens work with variable ND and polarizing filters?

Yes. The 58mm filter thread accepts standard filters across both categories, so you can adapt your rig as needed without additional adapter rings.

Does the ED glass element really reduce chromatic aberration?

ED (Extra-low Dispersion) glass is designed to control color fringing across the zoom range, particularly noticeable at longer focal lengths where aberration compounds.

Is this lens compact for a telephoto zoom?

Relative to full-frame telephoto options, the MFT mount and shorter flange distance keep this lens physically manageable, making it a practical telephoto choice for Micro Four Thirds systems.

Can I use this lens for both photo and video work?

Yes. The MSC autofocus system is specifically engineered for dual-duty stills and video work without the autofocus noise issues you'd encounter with older focus designs.
