Slightly off-the-topic here, but that's me. So here goes.
A Contax G1 (the most affordable) or G2 (the best of the two) with two lenses, the 28/2.8 Biogon and the 90/2.8 Sonnar. Lens hoods, UVs, a table top tripod.
I would then travel the world with this kit, as I've done before. With a dozen rolls of film, ideally better quality color neg as it's good and cheap and can be easily processed almost anywhere, things have greatly changed for the better in the analog world in the last few years.
This kit would keep me as happy as a porker in you know what, and I could still carry it all in a backpack. Win-win.
