I'm struggling to find a 1 pence coin in my house at the moment, loads of old change from holidays and pre decimal coins.




Off to the shops for some change 😆

Still looking for a penny, but found a hundred year old farthing instead🤭

Trying out the new rings, just an experiment...

F50mm f1.7 @ f11 reversed on DA*300mm. Straight out of camera, not cropped, no post processing.




This is fun!

It may well be fun, Steve but this is also b****y GOOD!

Roger.
The more I look, the more there is to see!

And now with the 1.4 TC inserted between lenses and camera... Again, straight from camera, not cropped, no post processing.




Too late to do any more this evening. More experimenting to come another day...

High praise from someone who specialises in the details of a fly's eye! Thank you, appreciated.

Depends on progress with domestic duties...

I'm going to have another go in a few days time, trying to focus as accurately as possible and with a less well rubbed penny! These were done using the camera screen but will try the flucard to get a bigger image on the tablet. 1/8 mm steps on the focus rack (Novoflex) should be possible in principle, perhaps a bit better if I'm really careful.

At the back of my mind is creeping up to reversing a 24mm on 300mm + 1.4 TC and attaching a Q via the Q/K adapter. That means approx 17x magnification and extracting the centre of the magnified image with lots of closely packed pixels. And there's always the possibility of reversing the Q 01 8mm prime on the 30mm. But the aberrations, vibrations, depth of field, diffraction ...

Oops, last but one sentence should have been '... on the 300mm'.

Found a One Pence coin so don't need to use the old coins

So this is my setup using my K3 with Pentax Bellows, Vivitar Extension tubes and a 20mm F4 reversed set up as below, penny stuck to door with Blue Tac:



This was a RAW image adjusted in Affinity to correct lighting issues:



Against the JPEG straight out of the camera:

Bloody cheat

The hundred year old farthing or sixpence pictures were taken with a 105mm Sigma DG Macro, I was not trying to pass them off as "Penny Macro", just showing what I may have to use if I couldn't find a One Pence coin for an image of the "IRB" letters, the farthing doesn't have any letters under King George's head, it is B.M.


Taken with an MX-1 in Macro Mode.

Another way around the focusing is mount the target on a separate focus slider on a tripod, line it up carefully with the camera-lens ensemble and then use the focus slider's screw to move the target. It's a lot lighter than the camera and stuff (which could move disastrously with the slightest nudge) and can be accurately positioned much more easily.



To focus the camera, 200mm lens and a 28mm reversed onto it, swaying about on a tripod would have been near impossible. Putting the plant pot on a slider made things far easier. For the sake of scale, that is money spider silk you are looking at.
Both the *istDS and the K5 are incurably addicted to old glass
