My wife and I are taking a trip to London and then on to Dubai at the end of this month. In all the excitement of planning, one thing I haven't decided on is whether or not I should drag along my 500mm f4L IS. I've traveled all over the US with it, but never taken it international. The big thing I'm worried about is that we won't have personal transportation there. We are basically planning on walking or taking public transportation. I don't have a bag for my 500, so typically I just put it in our rental car and travel around with it and it's no big deal.
I'm mainly into wildlife and aviation photography, but I'm not quite sure how much of that I'll actually get to do in either place. The weather in London looks pretty crappy so probably won't use it there. And in Dubai there is a wildlife sanctuary I wanted to visit, but I do have a 400mm f5.6 I could use instead. I love my 500, and I hate leaving home without it, but I feel it may be a bit too much of a burden for this trip.
Anyone ever traveled to either place and and drug big gear around?
