Just let me add that nothing six-legged was permanently harmed for this photo.
I regret to inform you that the apple did not survive my experiment.

Atrocity alert! (But not on a Cotty scale).
I thought I should check that the advice below was sound, so I attached an M42 Schneider 50mm lens to Pentax K tubes 2+3 by way of a M42-PK adapter, then used a PK-LM adapter to attach the tubes to my Leica M10 monochrom, since it’s the only full-frame digital camera I have, and took this picture of the top of an apple.
This is the full 35mm-sized frame, the apple is medium-sized, so the stalk thing at the top* is about 1cm diameter.

I've been able to come up with something presentable using a Pentax M 4/20 mm lens at f16 and a 12 mm extension ring. Due to the shallow DOF it needed a fair amount of AI sharpening in ON1 but, given the subject, it could well do with a bit of additional drama.
As explained in another message in this thread, it took me a good while to find out that the enamel at the back of the extension ring kept the camera from recognising that anything was attached and it refused to step the lens down. Some courageous treatment with a dremel solved this problem.
I'll let you all be the judge of the picture and the idea once the new gallery will be online. Just let me add that nothing six-legged was permanently harmed for this photo.
Thanks for all help and suggestions.
