Here is a photo of the ring flash prototype. As you can see, it's powered by the built in flash (quite powerfull enough for macro photography).

It's a great shot, lovely macro. I still can't understand how you got this wonderful invention to work? The "ring" goes around the lens? How does the built in flash illuminate it?

I use a tin foil to make a 'light guide' from a built in flash to the ring cavity (the small paper reflect/diffuses the light into the ring).
Here is another photo from the back side. As you can see, the macro adapter is also homemade :)

You are a specialist Domjan! This macro is absolutely magnificent. But please tell me how to created your own macro lens... ?! I'm so curious. :)
Congratulation and respects.

Thanks Csaba!
As for building your own, just look at the pictures :) It should be quite easy but every setup (camera, macro lens/adapter) is different.
Just:
1. Build a hollow ring around your lens
2. Glue a tin foil on the inside of the ring to make it more reflective
3. Make a 'light guide' from the flash to the ring (cut a hole in the ring to let the light in).
4. Glue a semi-transparent white paper to the front of the ring (for a better diffusion).
And that's it! :)

Thank you Robin!
As they say... we haven't the money so we've got to think. :)

Yes I know, You are a pure genius handy man dear Domjan!!! I like your great technique, but I'm a poor user not an inventor as You... ;)
I'm looking forward your following pictures...
Kind regards.

How does this attach to your camera? Is it just held in front? So light, focus and exposure are all manual? Seems very cumbersome to use.

Thanks but I really wouldn't call this an invention. It's mostly just paper (from a pizza box I forgot to throw away :) and glue. Took me half an hour to put together. Really anyone can do it.

Hey, Ron!
I attached a cell phone photo (hence the low quality) of the whole setup. My macro lens adapter uses the same mounting technique as the original Canon addons, so it's totally solid (no chance of falling off :) The same goes for ring flash addon. It fits tightly to my macro lens. Nice thing about it is that it's extremely light. The whole macro addon weights about as much as a one AA battery! Also Zeiss lens I am using is very good (sharp to the corner) and gives excelent magnification (this photo is not cropped and is sharp even at the full resolution).
Macro addon lenses can be fixed in position (often are) and you can still use a normal autofocus.
Even though I often use autofocus, sometimes it's simpler to set a fixed manual focus and focus by moving the camera (1" at most). Most of the time I use full manual mode, not because I have to but because I like the extra control I get that way.
Yes, extreme macro photography is cumbersome. DoF is extremely narrow (1mm!), you have to come within 5cm of a often fast and extremely 'alert' bug so there is almost never enough time to setup a tripod and you often find yourself in 'wierd' positions :) Maybe that's why it's so fun :)
Anyway, I would say that my setup is probably far, far less cumbersome than any dSLR macro setup. They are often extremely heavy, have even more narrow DoF (-> higher aperture -> higher ISO -> lost all 'lower noise' adventage) and most importantly don't have LCD live preview (makes focusing and frameing most macro shots next to impossible). Bottom line, me happy with my setup :) Canon G6 with a 50mm f/1.4 prime lens would be even better, but me happy :)
I hope I didn't bore you to death :)

No not at all. That is very informative and the picture says it all. Thank you.
