I'm back from the trip and all I have to say is... I wasn't disappointed. For those who pitched ideas for lens selections, here's the treat's from the trip. Not all are edited but these were the first edits.
My most used lenses.
2. 70-200 F/4L IS
I didn't even use the Panny, 24-105, 24L II (Didn't want to lug it around.), or the OM 50mm. I'm very happy I didn't bring the 2.8's!!! The F/4's were already getting heavy after several hours.
