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?

TC doesn't always drop resolution a much.

There is a drop in resolution and it was measured by photozone. Scroll down towards the bottom of this page to see the numbers with the TC
