China eastern always provide cheap flight from Shanghai to Europe. IIRC, for this June, the flight to London is about 650SGD equivalent, return include everything. Thus, I won't be surprise with the package deal, moreover it is by travel agent, thus they might get event cheap flight ticket.
Anyway, for your set up, if I'm in your situation, I will choose either
1. Tamron 18-270mm + Nikkor 35mm 1.8
2. Nikkor 18-55mm + Nikkor 35mm 1.8
Both with tripod.
If I go with your option 2, will I miss out some thing?:sweat:
I am not very for the idea to bring tripod....:think:
