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

Olympus 40-150mm f/4-5.6 R: MFT's compact telephoto workhorse

On a Micro Four Thirds body, the 40-150mm focal range translates to a 80-300mm equivalent, which puts wildlife at distance, isolates subjects at a portrait session, or pulls in architectural details without changing position. The MSC autofocus mechanism, Movie & Still Compatible, runs quietly and tracks quickly enough that it won't interrupt video audio or miss a subject moving across the frame. At 58mm filter thread, it accepts widely available polarizers and ND filters without specialty glass.

The ED (Extra-low Dispersion) glass element keeps chromatic aberration controlled at the long end of the zoom, where lesser lenses show color fringing along high-contrast edges like branches against bright sky. For travel photographers, the physical size matters as much as the optics: the retractable design keeps this lens compact in a bag and extends to shooting length in a single twist of the zoom ring. At 150mm on MFT, you have genuine reach without the weight of a full-frame telephoto system, making it a practical choice when you're shooting all day on foot.

Who It's For

Travel photographers who need telephoto reach without bulk will find the 80-300mm equivalent range covers a wide range of shooting distances in a single lens that fits comfortably in any camera bag. Wildlife and nature shooters working in quiet environments benefit from the MSC mechanism's low-noise autofocus, which won't spook subjects. Video creators shooting on MFT bodies get smooth, quiet AF tracking that doesn't bleed into on-camera audio. Portrait photographers at events can work the 150mm end to compress backgrounds and maintain comfortable working distance from subjects.

FAQ

What's the effective focal length on a Micro Four Thirds body?

80-300mm equivalent. The 2x crop factor of MFT doubles your reach, turning this into a serious telephoto zoom for wildlife and sports without the bulk of full-frame glass.

Does the autofocus work during video recording?

Yes. The MSC (Movie & Still Compatible) mechanism is designed to focus quietly and smoothly during video, so you won't get focus hunting noise in your audio track.

How much does the lens extend when you zoom?

It retracts to a compact size for travel and storage, then extends to shooting length with a twist of the zoom ring. This makes it practical for all-day carry on a walk.

What filter size does this lens take?

58mm. That's a standard size with plenty of options for polarizers, ND filters, and UV protection without hunting for specialty glass.

Does the ED glass really reduce chromatic aberration?

ED (Extra-low Dispersion) elements cut color fringing at the long end of the zoom, especially noticeable on high-contrast edges like tree branches against sky. You'll see cleaner edges compared to non-ED telephoto zooms at similar price points.

Is this lens weather-sealed?

The specifications provided don't include weather-sealing details, so treat it as an unsealed lens for the purposes of planning your gear protection in wet conditions.
