42.5mm f/1.7 portrait prime with built-in Power O.I.S.
On Micro Four Thirds, 42.5mm gives you a 85mm equivalent field of view, the classic portrait focal length, here in a package weighing just 130 grams. The f/1.7 maximum aperture gives you genuine subject separation without needing to stop down, and the 7 rounded diaphragm blades keep out-of-focus rendering smooth at wide apertures. At 50mm long and 55mm in diameter, it disappears into a small bag or fits flush on a compact M43 body.
Power O.I.S. is built in, which makes this lens useful on any M43 body, stabilized shooting is available regardless of what's under the hood. The stepper motor AF is quiet enough for video work, and internal focus means the barrel doesn't extend or rotate during focusing. Minimum focus distance is 0.31m, which gets you close enough for tighter headshots or small product work at 0.2x magnification. The 37mm filter thread keeps accessory costs low.
At its price point in the M43 ecosystem, a fast 85mm-equivalent prime with built-in stabilization is a genuinely practical choice, not a compromise.
Who It's For
Portrait photographers shooting on M43 bodies will find the 85mm-equivalent framing and f/1.7 aperture a natural fit for head-and-shoulder work at comfortable working distances. Video shooters benefit from the stepper motor's quiet AF operation and the stabilization that Power O.I.S. provides during handheld recording. Street photographers who want a tighter focal length for compressed framing will appreciate the 130g weight keeping their kit light. Event shooters working in mixed or dim light get a real-world advantage from f/1.7 without carrying a larger lens system.

FAQ
- What's the effective focal length on Micro Four Thirds?
- 42.5mm becomes an 85mm equivalent on M43's 2x crop factor - the standard portrait length, but in a lens that weighs 130 grams.
- Does Power O.I.S. work on all Micro Four Thirds bodies?
- Yes. Power O.I.S. is built into the lens itself, so stabilization is available regardless of which M43 body you mount it on.
- How close can you focus with this lens?
- Minimum focus distance is 0.31m, giving you 0.2x magnification - close enough for tight headshots or small product work.
- Is the autofocus silent for video?
- The stepper motor AF is quiet enough for video work, and internal focus means the barrel stays still during focusing - no extension or rotation.
- What size filters does it take?
- 37mm filter thread. Standard size, widely available and affordable.
- How does the bokeh look wide open?
- Seven rounded diaphragm blades deliver smooth out-of-focus rendering at f/1.7 without the hard edges you get from cheaper designs.
- Does it have an aperture ring?
- No. Aperture control is electronic only, via your camera body.
