Olympus Zuiko Digital 14-42mm f/3.5-5.6 ED AF Lens for Four Thirds System (requires mount adapter for use on MFT){58}

Olympus's Four Thirds kit lens with ED glass

The Zuiko Digital 14-42mm f/3.5-5.6 ED covers a 28-84mm equivalent range on the Four Thirds mount, the standard bracket most photographers reach for when they need one lens to handle everything from a room-filling interior to a tight portrait crop. The ED (Extra-low Dispersion) element in the optical formula is there to control chromatic aberration, the kind of color fringing that shows up at high-contrast edges in backlit foliage or window frames.

At f/3.5 on the wide end and f/5.6 at full 42mm zoom, this isn't a low-light specialist, but it's built for the kind of daylight, general-purpose shooting that makes up most of what any photographer actually does: family gatherings, walk-around travel shots, backyard documentation. The zoom range alone makes it a sensible one-lens answer for someone who doesn't want to swap glass mid-shoot.

Mount matters here. This is a Four Thirds lens, not Micro Four Thirds, so if your body is one of the mirrorless MFT cameras, you'll need an adapter to put it to work. On a native Four Thirds DSLR body, it mounts direct and functions as intended.

For anyone building out a Four Thirds system on a budget, or looking to round out a existing kit with a compact standard zoom, this lens does the job without asking much in return.

Who It's For

Photographers running a Four Thirds DSLR body will find this lens fills the standard-zoom role directly, no adapter needed, covering 14-42mm (28-84mm equivalent) for everyday shooting. Travel shooters benefit from having one lens that spans wide interiors through short-telephoto portraits without a lens change. Beginners building a first Four Thirds kit get a straightforward, general-purpose zoom to learn composition and exposure on before investing in specialty glass. Micro Four Thirds mirrorless shooters who already own an adapter can add this as a budget-friendly second lens, since the ED glass helps control chromatic aberration in contrasty scenes like backlit trees or window-lit interiors.

FAQ

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

28-84mm. Four Thirds uses a 2x crop factor, so the 14-42mm native range translates to that wider-to-tighter spread on any Four Thirds DSLR.

Will this mount on a Micro Four Thirds camera?

Not directly. This is Four Thirds, not MFT. You'll need an adapter to use it on a mirrorless MFT body like a Lumix GH5 or OM System OM-1. On native Four Thirds DSLRs like the E-30 or E-5, it mounts straight on.

What does the ED element do?

ED (Extra-low Dispersion) glass reduces chromatic aberration, that color fringing you see at high-contrast edges. It matters most in backlit situations or when you're shooting into windows and bright skies.

Is this lens fast enough for indoor shooting?

No. At f/3.5-5.6, it needs good light. This is a daylight general-purpose zoom, not a low-light lens. It'll struggle indoors without supplemental lighting or high ISO.

What's the zoom range good for?

28-84mm equivalent covers interiors, walk-around travel, family events, and tight portraits without lens swaps. It's a one-lens-does-most-things focal length on Four Thirds.

How does this compare to other Four Thirds kit lenses?

This is the standard Four Thirds kit lens. If you're building a Four Thirds system on a budget, it's the baseline zoom for general shooting.
