If you’re an Olympus OM-D E-M1 user, we’d suggest you hold off on updating to the latest firmware. Version 4.2, which added some focus stacking capabilities, seems to be leading to corrupt images and locking up cameras.
We’ve reached out to Olympus for comment and will update this post when we hear back. Until then—or, rather, until they issue a fix, since this seems like a legitimate issue—we suggest not updating, or staying away from the aforementioned features if you already have.
