I am really conflicted in my camera needs. Currently I am sporting a tiny RX100 and even that is rarely used as smartphones have become our main cameras.
We're going travelling for 3 months, the photos will be priceless, so I am willing to spend whatever it takes (within reason) to get the best possible photos from that trip.
Ideally I'd just travel with a single lens.
Looking at different options, I have a good choice of superzoom cameras with 1" sensor, stepping up from that is A6000+18-200 lens - a big sensor, but a dark lens and finally some full frame options, which are big, pricey and still not ideal (only up to 70mm).
So the sweet spot seems to be sony 18-200mm f3.5-6.3 lens, which is unlikely to give me many shallow DoF photos.
Question is do I need them?
I mean for travel I'd expect I normally need both the subject and the background in focus, so we know where the photo was taken. Most of the photos will also be taken in broad sunlight. I'm not sure if that's an argument for or against a smaller sensor/camera?
