Hello,
I´ve done some work on light conditions for macros.
Ring flashes were too expensive and my camera has no external flash connector.
My first try was to use 50 LEDs, but the pictures were "flat" and showed hard reflections.
The FZ5 like some other cameras offers a good opportunity to fix "bouncers" on top of the flash to dispense the light. You may have seen the fuji film-container solution elsewhere.

But this bouncer does not reach the region used in our macros.
It has to be bigger!
I have shown this bouncer in the panasonic forum before but it did not leave much impression (2 answers):

Here are two comparisons with:
left: direct flash middle: available light (still best, but....) right: bubbled bouncer
The transparent aspect gets lost, but the reflections are much smoother now!
... and it´s up to you to choose the size of the balloon.

Same procedure with the larva of a dragonfly

Here is the real life:
A green metallic bug sitting in a dim area.
Direct flash killed the green colours and the available light was not sufficient.
The ballon bouncer had to substitute the sun.
The only problem left is the transport of bubble bouncers in different sizes.
It needs some time to get this ballon on top of a shortened fuji film container.
Longer than a bug waits for you....

The fimcontainer needs a valve in the transparent part!
Fix a flexible piece of plastic with selfadhesive tape above a small drilled hole.
Apply a little bit of vaseline (grease) around the hole.
The balloon can stay on the container from now on.
It is inflated through the container. And deflated by a pin pressed against the "valve".
From now on the size is variable and the "setup" is fast.
The air will not stay forever, but long enough for a good series of shots!
Don´t forget to place spare balloons inside the container.

Please feel free to answer and to attach your own pictures.
I am really interested in your opinion!

in case you need a low budget eye-piece for macros:

Thank you Seemolf

that seems really an articulated solution, but the results look great.

Congratulations for your inventiveness

Thanks narmer,
this one looks more impressive.
I swear the bouncer produces better pictures.
But I need the LED light for focussing, as soon as my evf and lcd turn dark.
