I'm going to be heading to China next summer where I'll spend at least a week in Shanghai for the World Expo and at least another traveling the country side (Great Wall, etc...). I have a 7D coming in the next few weeks, but I'm looking for some recommendations as far as lenses go. I have a 50mm 1.4, but what else would you bring? I'll be doing a lot of hiking, so weight is an issue, but I'm also concerned with quality (of lenses, and images). I intend to shoot just about everything; people, nightlife, buildings, landscapes. Should I just get a 24-105? 24-70 and a 70-200? A wide angle? Any and all recommendations would be appreciated. Especially from those who have lugged their gear around a lot.


Thanks,
Jeff
