It would be interesting to note how heavy you are lugging your equipments around during photo-shoot.
As for me, I carry a body, 3 lens (combined range from 18 - 500mm inclusive of 1 macro lens), 1 flash, a laptop, a MP3 player, spare batteries and a tripod that weigh around 8 ~ 9 kg (weight inclusive of the camera bag) each time I go for photo-shoot. Rationale of this setup is to have the commonest equipments to cover a wide range of photographic opportunities (by this I mean the range of focal lengths). Though my setup is heavy, I think the weight is compensated by the wider opportunities of not letting a potential to slip by. This applies to both local and overseas trips.
I would like to find out what other clubsnappers are carrying and also include your rationale/philosophy for your owe particular setup. I hope I can trim my setup weight down further and I would like to know your philosophy better.
