The beetle is Agapanthus villosoviridescens the Golden-bloomed Grey Longhorn Beetle.

The lens was on the A7r3 and at 1/40 sec f11 ISO 400, cloudy daylight, hand held.

Images have been cropped slightly.

The stereo is crosseye.

OK, the view from above is not what I would normally want but it was all that was offered.

Fantastic, I would love one of those printing nikkors. I've just got a Zeiss Luminar to play with tough, and that might fulfil my macro needs.

Sadly I can't see the stereo, I found out last year that I am slightly crosseyed so I can't perceive any 3D imagery.

For these, you just need to be a bit more crosseyed! Follow your finger outwards from vertical to your nose and relax your focus.

I can sort of see something. The optician told me last year I have a slight turn in one eye, he said it is probably due to a blow to the head at some point. Had a few of those over the years, sadly.

Regardless, lovely picture, and inspired me to go insect hunting. How far from the insect was the Nikkor?

Here is my calibration:

Extension mm Working Distance (No hood) mm FOV mm Mag
145 390 36 0.5
225 210 17 1
340 155 10 1.7
385 150 8 2

The columns are present in editing view but lost on upload.

The body of the beetle is supposed to be 22mm long and the sensor 36mm but I have cropped maybe a third off.
