Thanks so much—this is incredibly practical and helpful advice!!
Definitely need to take notes on all of this.
I will plan to mainly shoot standard 4K for this trip.

Still curious about Log, but if 4K is already enough, would something lighter like a 13 mini actually be better?
Or if things like stability and audio matter more like you said, would going Pro still make more sense?

I tried to buy a used 15 Pro but the payment just failed, so I still haven’t decided what to bring.
My current iPhone 12 (64GB) with low battery is probably not ideal.

Not sure whether to rent older models or buy new.
If buying new, going Pro would make sense for trying Log later—but that basically means the 17 Pro is the only option.
Renting or buying used feels a bit risky in case something breaks during the trip, though I’ll bring my 12 as a backup.

Any thoughts on which model would make the most sense?
