It's Christmas and total boredom sets in so

Needle tip covered in dried Cyanoacrylate (crazy) glue.

 

16 shots,   200mm @ f/16 with a reverse mounted 50mm, and ring flash

Guessing about 7:1 mag ratio on the 7d, gets 4.5:1 on the 5d.

Wow.

How did you attach the reverses 50mm to the camera body ?

Some older pics of the setup, I have now figured out how to add another ring and mount my ring flash to the setup!

The 50 is actually reverse mounted to the 200 with adapter rings I got from B&H :)

You need to figure out the trick to fully open the aperture on the 50, every one of them is different.

The old FD canon I used needed pushing on a lever while poking a needle into a little hole.

 

The adapters
B&H General Brand 52mm Macro Coupler (Male to Male)
B&H General Brand 67mm-52mm Step-Down Ring (Lens to Filter)

No idea why that image is showing up twice.

 

I am working on getting a RMS adapter (Royal Microscopical Society) that lets you mount 25mm or 26mm microscope objective lenses to the tube lens.

 

This place has them, but the site still uses flash I think and it keeps crashing on me so I've been worried about hitting the order/pay buttons.

That is some crazy detail. Puts my simple 2:1 macro to shame; only thing it really needs is some more neutral lighting, feels a little too green

Here's the latest version of the setup where I managed to attach the ring-flash to the frankenlense.

 

The arm is a Manfrotto 131db side arm

The macro rail is a Manfrotto 454 micrometric positioning  plate.

 

The green bit on top of the pill bottle is the glue tube cap with the needle inside it.

Thanks, Peter.

I might be getting the wrong end of the stick here, but did you indicate that you can use, say, a 1.25 inch telescope eye piece to do this kind of photography ?

Not sure about telescope eyepieces,

with the right RMS adapter you can use microscope objectives as the main magnifying lens.

From all the docs I've read they seem to require a 200mm  tube lens to be attached to, which is the same I found with the reversed 50mm. Any shorter and it starts to vignette badly.
