Olympus 75-300mm f/4.8-6.7 II ED MSC M.Zuiko Autofocus Lens for MFT (Micro Four Thirds), Black {58}

Olympus 75-300mm II: 600mm equivalent reach in MFT glass

The M.Zuiko Digital ED 75-300mm f/4.8-6.7 II gives Micro Four Thirds shooters a 150-600mm equivalent focal range in a package that won't dominate your bag. The MFT crop factor does the heavy lifting here, 300mm on this mount reaches where most full-frame photographers would need a much larger, pricier optic to follow. ED (Extra-low Dispersion) glass elements keep chromatic aberration controlled at the long end, where lesser telephoto designs tend to fall apart on high-contrast edges like birds against sky or athletes against stadium lights.

MSC autofocus, which stands for Movie and Still Compatible, is engineered for quiet, fast focus transitions. That matters in two situations: video work where lens motor noise bleeds into audio, and wildlife photography where a loud drive mechanism spooks subjects. The 58mm filter thread keeps accessory costs reasonable, and the f/4.8 maximum aperture at 75mm gives you an usable wide end before the lens stops down to f/6.7 at 300mm.

For MFT system users who want serious reach without renting or committing to a much heavier rig, this lens represents a straightforward answer at a price point that makes extended telephoto work accessible.

Who It's For

Bird and wildlife photographers working the MFT system will get immediate use from the 600mm equivalent reach, enough to fill the frame with wading birds or perched raptors without a tripod-mounted super-telephoto. Travel photographers who need focal length range without checked-baggage weight penalties benefit from the compact form factor relative to its reach. Video creators shooting nature or event content will appreciate the MSC drive's quiet operation keeping audio tracks clean. Birding beginners upgrading from a kit zoom and looking for a dedicated long telephoto will find the 58mm filter thread and MFT compatibility an easy entry into the focal length range.

FAQ

What's the 35mm equivalent focal length?

150-600mm. The MFT crop factor doubles the stated 75-300mm range, giving you telephoto reach comparable to much larger full-frame lenses.

Why does the aperture change from f/4.8 to f/6.7?

Variable aperture design. As you zoom from 75mm to 300mm, the maximum aperture narrows-a trade-off that keeps the lens compact and affordable without sacrificing performance at the long end.

How quiet is MSC autofocus for video?

MSC (Movie and Still Compatible) is specifically designed for silent, smooth focus transitions. The motor won't bleed into your audio track, and subject focus shifts remain imperceptible on camera.

Will this lens work on my Micro Four Thirds body?

Yes, if your camera has an MFT mount-Olympus, Panasonic, and Blackmagic all use the same standard. Check your camera's manual to confirm.

What filter size do I need?

58mm. That's a common thread diameter, so ND filters, circular polarizers, and protective glass won't break the bank.

How does ED glass reduce chromatic aberration?

Extra-low Dispersion elements bend different wavelengths of light more uniformly, preventing the color fringing that plagues conventional telephoto designs at high contrast transitions.

Is this lens weather-sealed?

The specs provided don't indicate weather sealing. Check with Olympus directly if environmental protection is a requirement.
