I have a trip to Palau coming up at the end of January on board the Siren and am planning on purchasing a new a6600 (or a6400) prior to the trip. What lenses should I be looking at specifically for this trip? I'm considering any/all of the following:
1) Tokina 10-17mm
2) Sony 10-18mm
3) Sony 90mm
4) Sony 16-50mm + WWL-1 and/or diopter
Any other suggestions? I love the flexibility of the 16-50 with WWL, but could I be equally well served with just the Tokina and the macro lens? Would the 10-18mm rectilinear be a better fit than the fisheye Tokina?
I'd like to keep the gear to a relative minimum, so ideally not more than two lenses if possible.
