Re: OOPS! You are right.

Some of these results are at the finest resolutions of their tests, i.e. what they call a single 'blur unit'. For all we know the prime could be 0.1 of a blur unit and the zoom might be closer to 1.5, and this might actually be observable in photos.

Look at the F5.6 and F8 rows of the comparison image. Note that the inexpensive Oly 40-150mm has an area of bright pink both at F5.6 and F8. The Oly 45mm does not. The bright pink is an area of greater resolution than the darker pink shown for the Oly 45mm. So the test equipment had sufficient sensitivity to measure any greater sharpness of the Oly 45mm, had there been any.

If you look at the 40-150mm at 70mm and F5.6 you will see half the image area is the bright pink color.
