They're so small: the only good thing is that they rarely/very slowly movemove...

Reversed 24mm is a challenge to use at 12x without blocking devices...

Francesco,

I guess you used this reversed 24mm lens for your aphids.
50mm is not enough to get such a resolution.
My shots were taken with a 10* microscopic lens . The results with this lens were better than those taken with my 28mm reversed lens.

Ofcourse only parts of these eyes are in focus.

Nice shots again Sven. Great examples.

The 24mm seems to give off quite a bit of diffractions. Notice the antenna in these and the light. Natural lighting, 24mm Canon @ F/5.6 and the FZ10 @ F/8







DOF is what we would expect and that combination of F/stops might well cause the diffractions. The 100mm is still the favourite with the 50mm second. 35mm could be a good compromise.........maybe :-)

All the best and that dimple has always fascinated me Sven. Very interesting thread thanks.

Danny.

thanks for the excellent addition Danny!

There is diffraction of course. Mounting a microscopic lens close to the FZ5 is not state of the art. The distance should be around 160-170mm for my lenses

I was using cheap LED torches. This is cold affordable light.

I am dreaming of a full size shot of these eyes now.

My microscope is ready to take over (and helicon focus).

It is a pity that I did not buy any aphids embedded in amber. I will search for one! Eyes are well preserved in amber:

My lenses are optimized for embedded material.......
But you can see that this "second eye" has four lenses pointing to different directions. But I don' t think it is spinning around ;-)



These were the drops I was searching for.
A little gift from the "cow" to the shepard:



After seeing these pictures a friend gave me a macrorail!
Thanks Axel!
My new equipment is much better now:
(the small part in the middle is the camera!)



- cheap tripod (weight)
- pneumatic release as a compensation
- I can use my lcd again !!!!!!
- macrorail (old east german production)
- flash diffusor (if needed)

Many thanks for all the nice answers!

Sven
