Laowa 50mm f/2.8 Ultra Macro APO - Micro Four Thirds

The Laowa 50mm f/2.8 2X Ultra Macro APO is a manual-focus prime lens for Micro Four Thirds mount, offering a rare 2:1 maximum magnification ratio, APO-corrected optics to minimise chromatic aberration, an all-metal build, and a 215° focus throw for precise tripod work — all in a compact, lightweight package that focuses continuously from 2x macro all the way to infinity.

What makes the Laowa 50mm f/2.8 Ultra Macro APO special?

The headline feature is the 2:1 magnification ratio. While most macro lenses top out at 1:1 (life size), this Laowa goes twice as far — projecting the subject at double life size on your sensor. For Micro Four Thirds shooters, that's a genuinely big deal: the MFT crop factor already gives you extra effective reach, so a 2:1 lens on MFT delivers an extraordinary level of magnification without needing extension tubes or additional accessories. It was the first lens designed specifically to offer 2:1 magnification optimised for MFT cameras.

Sharpness holds up well even wide open at f/2.8, and image quality is considered on par with the Olympus M.Zuiko 60mm f/2.8 Macro — a lens widely respected in the MFT macro world. The APO (apochromatic) formula keeps colour fringing tightly controlled, which makes a real difference when you're shooting at extreme close distances where chromatic aberration tends to spike on lesser optics.

The 215° focus throw is noticeably wider than on most macro lenses, giving you much finer control when you're inching toward your subject on a focusing rail or tripod. Combined with the continuous focus range from 2x all the way to infinity, this lens doubles as a general-purpose 50mm prime when you step back from macro work — something the ultra-specialist Laowa 25mm f/2.8 2.5-5X Ultra Macro cannot do.

The closest direct comparison most MFT users consider is the Olympus M.Zuiko 60mm f/2.8 Macro. That lens offers autofocus and 1:1 magnification. The Laowa trades AF for a full extra stop of magnification (2:1) and the APO correction. If you need autofocus for moving subjects, the Olympus is the practical choice. If you're working on a tripod, shooting static subjects, or need that extra magnification reach, the Laowa is the more capable optical tool. The OM System 90mm f/3.5 Macro IS PRO is a premium alternative with 2x magnification and in-lens IS, but at a substantially higher price point even second-hand.

Who is the Laowa 50mm f/2.8 Ultra Macro APO for?

This lens suits photographers who are serious about macro work on a mirrorless MFT system and are comfortable with manual focus. That includes:

• Nature and insect photographers working from a tripod or focusing rail, where the 215° throw gives you pixel-precise control over your focus plane.
• Product and still-life photographers who want to reveal fine textures — fabric weaves, watch mechanisms, jewellery details — at double life size.
• Science and technical photographers who need consistent, high-magnification results with minimal colour fringing thanks to the APO correction.
• Street and portrait photographers who also do close-up work and don't want to carry two lenses — the infinity focus capability makes it a usable everyday 50mm on MFT bodies.
• Budget-conscious macro enthusiasts who want 2:1 magnification without spending on the OM System 90mm f/3.5 Macro IS PRO.

It's less suited to wildlife or event photographers who need fast autofocus, or anyone who regularly shoots handheld macro at slow shutter speeds without in-body stabilisation.

Buying a used Laowa 50mm f/2.8 Ultra Macro APO

Buying a pre-owned Laowa 50mm Ultra Macro APO is a smart move for macro photographers watching their budget. The all-metal build means these lenses age well — the barrel doesn't flex or creak, and the aperture ring stays precise. When checking a second-hand copy, focus on a few specific things:

• Focus ring smoothness: Run it through the full 215° throw. It should feel consistently smooth with no tight spots or grinding. Macro lenses get heavy use on rails, so the helicoid can wear unevenly.
• Front element and internal glass: Check for fungus or haze, especially if the lens was stored in humid conditions. Minor dust is normal and doesn't affect image quality.
• Aperture blades: Look for oil on the blades, which can cause uneven exposure or smearing in bokeh.
• Mount contacts: The MFT mount is electronic on some versions, so check that the mount pins (if present) are clean and undamaged. Since this lens is manual-focus and has no autofocus motor, there are fewer mechanical failure points than on AF lenses.

Every used lens sold on Camera-tweedehands.nl is individually photographed and comes with a minimum 12 months warranty, so you can inspect the actual item before buying and have full peace of mind after.
