You can improve the close focus distance with a diopter filter. I handhold a +5 B+W in front of my RX100. They're $25.
Improve 'close focus" distance by how much? A couple inches? IMHO still too short for other than static subjects.
... I don't understand your response. A "couple inches" is a lot in close up photography.
Plus the OP noted "Quality Macro capability required"; diopter filter not:-| going to help with a lens soft corners, may make worst.
I never claimed it was equal to a macro lens. You pointed out close focus as a deficiency of 1" sensor cameras, and I'm offering a workaround to improve it...
Sorry IMO not much of a workaround ... as I clearly noted for use "for other than STATIC subjects". I first played around with various close-up filters over 30 years ago.
... Nothing more. And I don't see any problem with the corners....
Really?
None of your images have any details in corners to be able see any corner softness issues compared to image center sharpness.
Apparently you did not thoroughly read the OP's first post. Unless insects are stationary/ docile be difficult to get pics of insects (or other small living creatures) with lens only inches from subject; i.e., not casting shadow on subject depending ambient upon light source, and generally too close to use built-in flash.
With the penny images there's not any worthwhile corner detail i.e., needs to be pic of paper currency or anything with fine details that FILLS the entire frame. Also to do any center-to-edge sharpness evaluations, the camera's sensor needs to be parallel/ level with the surface the item being photographed on.
The corners of the flower pics are OOF due to lack of DOF. Actually due to the f/1.8 there's really not much of the center flower that's in sharp focus.
Actually your flowers to make a point that in the real 3-D world close-up pics, soft corners should not be that critical due to OOF caused by shallow DOF.
Closest focus with no filter.
With +5 close-up filter.
No filter.
With +5 close-up filter.
