[Note Guidelines] Photographer's Note
Taking this type of subject needs to be quiet and very slow, so not to create movement. The best way is to use handheld. But it may cause vibrations. The best way is to use light lens, like this kit lens and extension tube. sometimes it work and sometimes its not so sharp.
My experience its quite workable.

The compound eyes of insects, mantis shrimp and millipedes[1] are composed of units called ommatidia (singular: ommatidium). An ommatidium contains a cluster of photoreceptor cells surrounded by support cells and pigment cells. The outer part of the ommatidium is overlaid with a transparent cornea. Each ommatidium is innervated by one axon and thus provides the brain with one picture element. The brain forms an image from these independent picture elements. The number of ommatidia in the eye depends upon the type of insect and ranges from just a handful in the primitive Archaeognatha and Thysanura to around 30 thousand in larger Anisoptera dragonflies and in some Sphingidae among moths.[2]
Ommatidia are typically hexagonal in cross section, and approximately ten times longer than wide. The diameter is largest at the surface, tapering toward the inner end. At the outer surface there is a cornea, below which is a pseudocone which acts to further focus the light. The cornea and pseudocone form the outer 10% of the length of the ommatidium.
The inner 90% of the ommatidium contains 6 to 9 in the case of some butterflies[3] (depending on the species) long and thin photoreceptor cells often abbreviated "R cells" in literature and often numbered, e.g. R1 through R9.[3] These "R cells" tightly pack the ommatidium. The portion of the R cells at the central axis of the ommatidium collectively form a light guide, a transparent tube, called the rhabdom.
In certain flies, the rhabdom has separated into seven independent rhabdomeres. This has required the rewiring of the eye such that each ommatidium now has seven axons leading from it. The advantage to this arrangement is that it increases the number of picture elements by a factor of seven, without increasing the number of ommatidia.

Hello Foozi,
It's an incredible picture! Great control of the DOF (the main difficulty I guess), perfect POV for an impressive portrait of its face, perfect sharpness.
A great shot!

Hello Foozi,
Your macro images are incredible, as is evident by your last three posts. This particular shot has awesome DOF and super sharp detail.
I have a set of Kenco extension tubes, but must admit have rarely used them. After seeing what can be accomplished with them I will make it a point to try them more often this summer. Great work!!
Ron

Ciao Foozi. Impressive MF! Professional macro indeed. Fantastic light.

Roberto

The muted mesh compound eyes are just breathtaking Hj Foozi.
Lovely work with brilliant editing. Well done!!

Hi Foozi,
Beautiful shot, fantastic details on the fly's face. And the title's more than perfect - he's like wearing trendy sunglasses. :-) Masterful job, bravo!
Best regards, László
