I know it comes down to personal choice but am curious what camera you would take.
In July I'll be heading to Norway and Iceland for approximately 10 days. I will have a rental vehicle in both countries and plan on doing at least 3-4 hikes (likely ranging from 4-8 hrs each). There will also be some general site seeing when I'm not hiking.
My options are a Canon G1X (MK1) or my Canon 80D. If I took the 80D I would likely only take the 15-85 lens and leave the 70-200 at home to cut down on weight.
No matter which I take, I have filter adapters for each and will bring a CP filter and a 6 stop ND. I will also be bringing along a lightweight tripod with ballhead.
. Practical? Not necessarily. But like you said, personal choice, and that's just me.
