I was befuddled as well until I saw that.

They tested the G9 with the Nocticron 42.5mm f/1.2, and the Oly EM 1.2 was tested with the Oly 45mm 1.8.
A sharper lens produces more detail.

The E-M1ii is also slightly misfocused as it was done before DPReview implemented their new focusing procedure. I spoke with Rishi about it when they wrote the article related to the early soft A9 results but I guess they've been too busy to go back and redo the E-M1ii.

At the apertures DPreview uses for test shots typically F/5.6 { a good argument to use a more optimum aperture there
} the difference in resolution between these two lenses is insignificant 
I suspect more mundane factors like even small focus differences or AA filter strength would be far more relevant

As I mentioned above at the aperture used there is negligible difference between these lenses

Of course they look the same on a E-PL1....far cry from a 20MP sensor with no low pass filter.As I mentioned above at the aperture used there is negligible difference between these lenses

The point is the aperture choice of F/5.6 is below peak performance for both lenses and will achieve very similar results no matter what sensor you put it on . Now were they both set at their optimal aperture on a 20mp sensor one would indeed expect a larger divergence of results. Why they use F/5.6 is of course the real questionOf course they look the same on a E-PL1....far cry from a 20MP sensor with no low pass filter.As I mentioned above at the aperture used there is negligible difference between these lenses

And I do think that issues like focus accuracy etc will have more impact than any differences in resolution at F/5.6 , the 45mm F/1.8 is no slouch Imaging resource have test images for both cameras using the excellent FT 50mm macro

While I wish what you say is true, as it would result in lighter lenses and more money in my bag, I think it is not true for average to good lenses, particularly in the edges......where the best lenses get more resolution out of high resolution sensors.The point is the aperture choice of F/5.6 is below peak performance for both lenses and will achieve very similar results no matter what sensor you put it on .

Look, the output, both JPEG and RAW, of the G9 looks much better than the GH5, Pen F, and E-M1 Mark ii......the only difference is the lens. Its gotta be lens or technique, and I can believe poor technique was used on all three of the other cameras as well.

That and the focusing procedure that DPReview updated after the soft A9 test.

What was the different procedure? Could explain things......

Interesting. It makes comparison of earlier with current evaluations more complicated. However, if one reads the whole explanation, trying to determine small differences in performance is not possible given the error of measurement.

Yeah, I wouldn't use the tool the measure sharpness, it's simply not setup for that purpose. I remember having this exact conversation with someone who was popping into almost every single thread claiming that the GH5 was 10% sharper than the E-M1ii without taking the nature of the test into account.

Not much to do with the lens. If you want to see a good comparison look at the Pen F vs the G9
Thanks everyone. My main concern is that my EM1.2 is not really that much worse than the G9. Like others have said, the 45 1.8 is a pretty good lens and shouldn't look that much inferior to the 42.5. Something not up to snuff here.

It is simply technique. The G9 raw is almost indistinguishable from the PEN F.

Unless there is some new mFTs sensor, the G9 is almost certainly using either the MX269 (GH5) or MX270 (E-M1.2), so why would one really expect much difference other than that caused by the lens, camera settings, or measurement error.

Maybe because they used a lens on the G9 that is $1000 more expensive than the one shot on the EM1.2
