I agree with 2 things,
@markjwyatt :
1) it's not a macro lens and therefore won't produce Macro result, therefore
2) your pic doesn't match the criteria set.
I use Zuiko 50mm 1.4 lens daily and it too can focus at 45cm
I also have Zuiko 24mm 2.8 and it can make focus at mere 25cm away from subject.
BUT
They don't project tiny objects 1:1 or even 1:4, making them useless for macro, mounted the correct way. But you can fix it - I'd urge you to hold reversed in front of camera and making true macro submission
Here's an easy how-to:
- have a strong light source and a tiny subject, meter the scene and note the value;
- remove lens, set and fix the aperture to your liking and hold the lens reversed in front of camera;
- rate 1 step slower than metered and give shutter priority in your mind - shouldn't be lower than lens focal length +1 stop. Meaning that with a 50mm lens you don't want to be slower than 1/125 to have a chance to capture sharp handheld macro;
- adjust focus by moving/leaning physically against something
- bracket
- WIN!
