According to DXO:

1. Olympus 75mm 1.8 is top

2. Then equal second is the pan leica 25mm and panasonic 20mm

3. olympus 12mm f2, 60mm macro, sigma 60mm f2.8 and panasonic 35-100 f2.8 zoom

4. olympus 45mm 1.8, oly 12-40 f2.8, pan 12-35 f2.8, pan 7-14 f4

These were all tested on the EM1,

The new pan leica 42.5 f1.2 and 15mm f1.7 have also been tested but not on the EM1. They were tested on the EM5.

The 42.5 1.2 has been but rates as 12mpix on the EM-1 Vs 13mp on the EM-5....same with the 75. they have most lenses as being a shade sharper on the EM-5 than the EM-1.

That's surprising. You'd think the EM1 would give sharper images because it has no AA filter.

The 42.5 is sharper than the olympus 75mm 13mpx over 12mpx.

Depending on the camera....the 75 scores badly on the GX7 (only 7 Mpix)...many think the GX7 results have had something go wrong though.

The 15mm has the same sharpness as the pan leica 25 and panasonic 20mm.

These are just sharpness results.

Edit: sorry just read your title again and you wanted just Oly lenses. Not sure why but I suppose you can filter out the other lenses mentioned.

Sharpness is very much lens AND camera dependant for DXOmark.

I tried to find them all on EM1 to give fair comparisons but couldn't find the pan 15 or 42.5 on the EM1.

For instance the FF A7 kit lens rates 22Mpix on the A7R but only 15Mpix on the APSC cameras tested on.....obviously the larger sensor size plays a big part in the scores.....the A7 kit lens IS a nice lens but no one would argue it is better than the Oly 75 1.8 on any 16mp m4/3 camera.

If you look at a lens, you can see a selector for what cameras a lens has been tested on,    42.5 is tested with lots of cameras, (12MPix on the EM1), 15 is tested on a few cameras too including the EM1 (11MPix).
