It could be the lens or it could be a phenomenon I and others have
noticed, and that has been commented on in other places, that sometimes
a digital image will have no zone of absolute sharpness, you did
everything right but there isn't anything in the photo that is actually
in sharp focus. Shutter speed is high enough lens is stopped down if
not it's optimum at least not to the point where diffraction begins to
really effect the image, but still noting is sharp.
I don't know of any theory that explains this, but it's been noted. I
probably saved a bookmark to the discussion, but that was a few years
ago, and I've since upgraded everything twice so a lot of things that
didn't seem to be important got lost.

Jay,
When I looked at the photo, "wow!", I was impressed with the colors
and the composition.
But then I realized that something was bothering my eyes.
At first I thought that the photo was oversharpened. But when I looked
closely, I realized that the tree flowers are not sharp.
Actually, I am having hard time finding where the focus is. Either it
is back-focused, or you have a motion blur... (or something is out of
whack with the lens).
There is also a possibility that it is overcompressed with JPEG
processing.

A couple weekends back I made my annual visit to our local historical
camera
collectors swap meet in hopes of finding a K version of the SMC
28/3.5. I
wasn't that lucky (I usually find a gem there), but I did find an M
28/2.8
and a K 50/4 Macro. I shot a few images with the 50 on my Sony A7II
and was
pleasantly surprised at the quality of this 1970's era lens. Here's
one of
the shots taken at Seattle's Washington Park Arboretum.
