Last trip I went on I took the kitchen sink and came home with very satisfying negatives to print. After much travelling I've sort of decided that taking the lightest camera isn't really for me - because I'll always end up wanting bigger negatives. So now I drag around a 5x4" field camera kit (mostly wider lenses), and on days when I lack the enthusiasm to lug that about, I take a 6x8cm rangefinder with a standard lens - a great street photography camera. I am sure my motivation will ebb as I get older, but right now the reward is getting home with that film...

Somedays, walking up hills, I hallucinate about carbon fibre tripods, and miniature spot meters...

In summation - take the camera you 'want' to take.

Marc!
