I fly to Beijing tomorrow. I'll be there for a week and a half, mostly work, but there will be a side trip to the Great Wall and a weekend to explore Beijing (smog permitting). I did the Forbidden City a year ago.
Normally I would take K-3, DA16-85, DA15, DA40, DA55-300, which is pretty compact. However my son has shot through to far north Queensland with my K-3, DA16-85, Tamron 90 macro (as well as his own 50-500 Bigma). So, should I take
- K-5, DA 18-135, DA15, DA40, DA55-300; or
- K-1, DFA28-105, DFA15-30, DA55-300.
The K-5 has a very stiff on/off switch, but is useable. If I took the K-1, I could substitute the DFA*70-200 for the DA55-300, but the weight is a worry. I could also substitute the DA15 for the DFA15-30 and shoot crop mode or 1:1. A further option is to take my only other remaining FF lens, the Sigma 35mm Art, which would be good for low light, but otherwise the 28-105 covers it pretty well.
Any advice or thoughts?
