Well, we're off to Vienna for a couple of weeks, and we have a day and a half in London on the way. This will be my trickiest trip yet in terms of how much camera gear I can carry, as we have the baby and pram to contend with. I'll probably just take my Blad in a Lowepro Microtrekker with just the 80mm lens and one spare back and the light meter. It's a business trip for me anyway (not for the other two). I'll take one of those tiny mini tripods too, and a few rolls of film. It's going to be a great trip and any photo opportunities will just be a bonus.
