Holy moly, just studied a penny and never even knew that was there. By'eck it's little

That is a lot of macro.
I detect a challenge!

ok, I had a go.
first I'd like to say MAN is this a difficult challenge. All in good fun!
I don't have any extension tubes, so instead I have mounted the following
Tamron 90mm SP Macro + 3 2x converters (2x Tamron SP flat field ones and a Tokina RMC) with a Zeiss Flektogon 35mm reversed at the front of it all.
It's a bit dark with all those converters, so I used a desk lamp directed straight at the penny to give me enough light to focus by and then fired a flashgun manually during a 2 second exposure to provide the actual light in hope of reducing noise by keeping the exposure short and the ISO low.
This is the best I have managed

Nice one Mongoose..
A challenge indeed then..
Sadly again, only for those with a late 90s onwards 1 pence piece.. post the greatest magnification of IRB.. it will be taken on trust that no-one blew up a picture to suit.
In the words of Arnie.. I'll be back.. I haven't tried reversing a 300m 5.6 off of the soligor.. and I have another 2x converter to hand..
Without glasses, I wouldn't be able to put my socks on of a morning, so this should be interesting.
Cheers

Not nearly as impressive as some of the other attempts above, but this is my offering. Quite a fun challenge to set it all up - the coin was blutacked to the wall with the camera on a small wheely table that I could move back and forth to focus. couldn't have used a tripod as the whole thing was about 18 inches long

Ist DL2, 65mm worth of extension tubes, 300mm lens, + 135mm + reversed 50mm (+ all held together with sellotape and a bit of luck)
It makes one realise what a really flexible set up an slr system is
liam - your sensor looks pretty grubby
Mongoose the clear winner at the moment...

mr Ist that sounds a pretty mamoth setup! unfortunately the picture isn't showing at the moment neat idea with the focusing, it took me AGES to get mine even as close as it is.
my 35mm zeiss was selotaped to the inside of the tamron's lens hood. Good to get the old ingenuity going from time to time isn't it?
edit: picture has apeared now, nice one

Hi Mr ist,
first.. your photo doesn't display.. although I've followed the link and it's pretty good..
OK, so it does now..
I noticed that about the dirt.. I'll have to give everything a good clean.
I used a tripod, but I hung it pointing down and used the centre column winch handle as a focussing adjuster. As long as it's perpendicular, it works fine.
Cheers

Crazy !
Wouldn't it be easier just to get a microscope?? Say a scanning-electron one

My wife thinks you all need to get out more
BTW Why is nobody using bellows any more, when I get back I might give it a go (she knows I'm sad anyway)

Yeah but, no but..
In the same vein, Captain Webb could've just got the ferry..
Hmmm.. I wonder if you can reverse a 500mm mirror lens..
I'll find out soon enough. DOF in microns.. anyone for doughnuts.

Wait for it....
Ta da!!

Actually using the 70-300 at 300mm. 6 extension tubes are around 140mm. Got another 3 somewhere...
As an exercise in patience, it's been rewarding, but practical uses...? Bearing in mind it's taken me about 30 minutes to focus the thing.

I thought today I would see how macro I can go..
Sadly this can only be checked by the British contingent (unless you have an english penny later than the late 90s).
Dig in your pocket and get a shiny penny out; now have a look underneath the Queen's neck.. just between that and the EL of Elizabeth's name, you can just make out three letters IRB..
..well here they are. This is uncropped, and except for a little clean up, is as it came out of the camera..
I tried measuring it, (what?? with my eyes) and the image represents just a little over 1mm.. call it 1 1/4mm for the ease of maths, and thats 20x magnification..
I'd hate to think what the DOF is at that magnification, and that was as good as I could get the focus, but I'm guessing it'll be measured in microns rather than feet..
Now, as the schools have been closed today, here's your little known fact.. IRB stands for Ian Rank-Broadley, the sculptor who originally designed the portrait for the coin. Here endeth the lesson..
What I used: DL, Soligor 70-210 macro lens (at full macro extension) with two 30mm extension tubes, one 2x converter, and a 50mm 1.7 reversed over the end. I'll see if I can get any closer later in the week.
