A beautiful car, from the decade the pentaprism and its flipping mirror were invented!
Hmmmm I'm a methodical photographer, years and years of commercial photography has done it to me!However, what I don't get is why this is a big deal, or a deal of any size. The Pentax K3III is designed and intended to be primarily an APSC wildlife/action orientated camera. Not many of its intended userbase are going to be doing much static studio work at 1/60 sec at low ISO.
Granted I haven't taken many photos with it yet, but I don't think I've taken many slower than about 1/360 sec. But you never know. I may one day want to take pin sharp photos of a pack of cards and a paint brush. So now I guess I'm armed with the knowledge to avoid 1/60 sec at low ISO.
But from time to time ones need to do 1/60 or less for paning for instance.I have no doubt that DPR found in their test that there was some slight blurring that may or may be caused by shutter shock at 1/60 sec at low ISO. And, I have no issue at all with DPR pointing it out in a test of a static studio scene. Presumably that is a point of doing such tests.

An Edsel, the other day outside a liquor store in nearby Sierra Vista. The owner older like his car, but both of them still running fine. The Edsel had a huge motor just when people started wanting smaller cars. And then, say the psychosexual car design experts, it had a female-shaped grill when people wanted male-shaped extrusions. In any case, not sure if it's a good analogy for the K-3 faux issue? Maybe Teslas, not the self-driving headlines but the repeated small maintenance problems that aren't solvable...
From exif they used the DA* 55 f1.4 at f5.6.
It was tested quite well and it is well established that this is indeed what is happening. ES shot is sharp. Different exposure times are OK too.
This makes no sense. There are sharp photos at ISO 100/200 (switch to the other lighting). The blur has NOTHING to do with ISO, only exposure time.
The lens is NOT the problem. Yes, it is soft at corners but the center should be perfectly sharp.
Plus .. the same lens was OK in other images. It is NOT the lens. Yes, it is somewhat poor in the corners but not bad overall.
At 1/60 of a second, depending what focal length you are using, you're not really guaranteed a sharp image every time. It is my impression that in the old days before image stabilisation, many used 1/100 or even 1/200 at normal focal lengths to be sure their pictures would be sharp.
I have what I believe is shutter shock on a K5-IIs between 1/60 and 1/180, and it also seems intermittent. It happens more often than not, but some shots are perfectly sharp at those same shutter speeds.
Is that on a tripod or hand held?
Mostly hand held, which is why I'm not positive that is the issue, but the blur has a very distinct look and direction to it. It also goes away at 1/45 and lower, and 1/250 and higher shutter speeds. Sometimes it's just images that are a little softer than I'd expect, others there an odd vertical doubling.Is that on a tripod or hand held?
I very rarely use a tripod, but I have never noticed shutter shock with my K5-II. However, it is also possible that I am a kak photographer
Do we have photos taken with that lens at resolutions K3iii delivers?
Why would this lens be OK with one exposure time and not the other? Aperture matters, yes, exposure time, no. That is why the reason for this softness .. the blur .. is not the lens but camera shake.
As a suggestion if you want to pursue this... there isn't much in resolution terms between the KP/K-70 and the K-3 III. There are samples in the lab scene widget, and probably lots elsewhere on the web. EXIF info should tell you whether DPR has used the exact same copy of the lens for the other bodies.
Different ways of processing by the camera due to different settings ...
