Eikin, just thought you can do with a little lesson about Japan before you come here... http://www.youtube.com/?v=E8c2fMDatoU
thanks nicZnap, zaren, madmacs, pop, Chris and mojito 
madmacs: yup that's one of the key differences, and i found some interesting information from the following website: http://www.ucmp.berkeley.edu/arthropoda/uniramia/odonatoida.html
While both dragonflies and damselflies belong to the Odonata and share many common features, then are a number of noticeable differences as well. Even before hatching from the egg, differences in morphology of the egg distinguish dragonflies (Anisoptera) from damselflies (Zygoptera). Dragonfly eggs are round and about 0.5 mm long, whereas damselfly eggs are cylindrical and longer, about 1 mm long. Similarly, the nymphs (larvae) of the two groups differ. A larval damselfly abdomen is longer and narrower with three fin-like gills projecting from the end. Dragonfly nymphs are shorter and bulkier, and the gills are located inside the abdomen. The dragonfly nymph expands and contracts its abdomen to move water over its gills, and can squeeze the water out rapidly for a short burst of underwater jet propulsion.
In dragonflies, the rear wings have a broader base and are larger than the front pair. Damselflies, by contrast, have front and hind wings similar in shape, and as a result they fly slower than dragonflies do. Also, dragonflies do not have hinges enabling them to fold their wings together when resting, though damselflies do. This feature of the wings is the key morphological feature distinguishing adult dragonflies from damselflies.
Chris: i use to work with the reversed 50mm setup quite sometime ago, currently using the sigma 180 macro lens
and thanks erthling for the video link, that's really good :thumbsup:
