How can the image quality out of the EM1 be too grainy at ISO200?

It's only possible if OP underexposes. It can be grainy if you shoot high contrast scene and boost shadows a lot, but it's not what many people do, so it's probably not the case here.

Especially when OP says that E-M1 is noisier at base ISO than E-5, a camera with 6 year old sensor. This tells that mastering exposure and camera settings properly should be the first item in to-do list.

As for comparison test - close-up pair shows that 100-300 is sharper. But, at least some telezooms can show good quality at closeups and then degrade at longer focusing distances. So, 1st pair should be more relevant comparison. I also wonder if 0s anti-shock was enabled during the test.

And regarding the first image pair - I have a weird feeling that 50-200 shot was focused farther than what crop shows, above cropped area. I could be wrong, of course. OP, would you be able to show full image?
Also, was there any reason to choose non-flat, inclined surface for lens resolution comparison?
