I am comparing IQ at overlapping focal lengths, on a EM1 Mark 2, and am having a lot of trouble seeing a difference, even with pixel peeping to the max.

Are my samples unusual, or do others have similar experiences?

I would expect a zoom lens with a TC14 to lose a considerable amount of resolution, so I would be somewhat surprised if the 100-400 were not somewhat better in the overlapping focal lengths.  How are they between 100-150 without the TC14 on the 40-150?
