May I suggest overexposure, possibly implicating diffraction?

i try dialing down exposure in strong daylight. The photos I get with positive exposure compensation seem similar and indeed it may be difficult to find where u focused.

I was wondering about whether my practice of ETTR was making it worse.

I don't understand the relationship between overexposure and diffraction though. Can you explain further?

Cheers

PS I have some more test shots to share later. I'm sure now that it is not simply diffraction (though that plays a small part). I am reasonably sure now that shutter speed is the single biggest factor here.

went back and seeing your aperture it shouldn't be defraction.

by the way, another possible problem will be say shooting in broad daylight with aperture wide open but again that's not your problem.

exposing ETTR is an issue as OLY cameras tend to overexpose in daylight and underexposed indoors. What I do, for my needs, is in outdoor environs I underexpose, and  overexpose indoors.

I do feel using ETTR maybe causing the problem.

i don't find the focusing issue, and this is with ep-3, ep-5, em-5, em1 and epl-2...but then that's just my perspective.

i do hope you find a fix
