You have enough time to learn, you should find somewhere flat and clear and learn to fly and film and build confidence in your drone. I would not want to take a new drone out the box and fly it the first time over terrain where I might not be able to retrieve it or worse it falls out the sky onto people and thats with some experience flying. My
Mavic 2 Pro was stolen in italy a couple of weeks ago and im going back through this process to make sure I have a reliable replacement.
I would recommend a set of ND filters (I like Polar Pro x6) so that you can use ISO 100/ f4 / 25-30fps. F4 seems to be the sweet spot for me, also consider adding some sharpness to the custom profile for photos.
The other tweaks I like to make is the sensitivity of the sticks/gimbal, there are advanced settings that will slow down movement and braking speeds so that you can get smoother video.
Also note that Iceland is starting to ban drones from tourist hot spots due to incidents, best to keep an eye out for signs.
Very jealous I would love to go to iceland.
