So answer is nope. It's a characteristic of the guy driving the digital camera.
I found an old Sigma AF 35-80 and then screwed my 50mm Pentax SMC onto it backward. Got vignetting at 35mm (cameraside) but after 50mm or so it went away (even at f/4). I shot this one is at f/18 (f/2 on the 50mm always) and the depth of focus is still absolutely silly shallow. I was trying to do these shots handheld at twilight in a decent breeze. With proper lighting and a subject that would hold still, it would be a fun way to shoot closeups. I shot this one (and everything else) with the Sigma (camera-side) at 80mm. It's uncropped. That's a sensor full of geranium insides.
