Is this lens performing normally?

I had reason to use my 20mm f1.7 wide open yesterday, and was surprised at how soft the corners were.  I took a few quick test shots today and would be grateful for your opinion.  Is it normal?  I don't have another copy to compare.

Camera was OM-D EM-1, exif in the photos

I still like the results stopped down a bit, but what about the f1.7 shots?

Of course, there are really no  corners to compare in these shots

All shots RAW, with default lightroom sharpening at 25, no other adjustments.  Of course I can make them look better with some PP, but want to show them as they come

thanks

tom
