NO EFCS in M6 II: a real shame

This is an example of my tests with the 15-45mm. It's mostly the same story with the 55-200 and the 28mm macro.

EF-M 15-45mm at 45mm, f/6.3 , 1/80s. E-shutter on the left. On tripod with delay.

What is this? A photograph of a video screen? A photograph of a screen-printed target? Or what?

I'm pretty sure this is not a valid comparison of two images.

It's oddly blocky. (Not pixelated, but blocky.) And the one on the right has noticeable lateral chromatic aberration. A mechanical shutter does not create chromatic aberration. The photo on the right was not created in the same way as the one on the left, and was apparently not centered in one or another lens that was used to make the photo. We don't even know if it was in focus.

I know the EF-M 15-45 is subject to shutter shock. I have written about it myself. But this is not very good evidence either way.

By the way, there is an easy way to mitigate the shutter shock. I don't routinely bracket exposures any more. Thanks to the live 3-color histogram, that is less necessary than it used to be. And for action photos with a repeating shutter, I would use high shutter speeds anyway, and the shutter shock is not visible at high speeds.

I wish the shock were not there, but it's not the only camera ever to suffer from this problem. Some very expensive flagship cameras have suffered from serious to severe vibrational artifacts in recent years.
