check re what Paul said, but as to the sharpness but all the guys
looking at ths photo on a little smart phone screen or small Ipad
probably think it is razor sharp... The blossoms don't look sharp to me
on my large screen desktop, but it doesn't matter... I'm thinkin j that
"the answer friend , are [blossoms] blowin in the wind"

We’re looking at a low-res image here folks. It’s not really possible to
determine sharpness based on such feeble evidence.

The twigs on the tree & the shrubs are all look sharp.

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.
