I'm thinking of buying an Oppo Find X9 Ultra. Alternatively I‘m considering the Vivo X300 Ultra or Pro.
I would be happy if you can share your experiences:

My main interest is taking macros of insects and plants and taking zoom pictures of birds in the field.

Battery life:
During an excursion in the field I can easily take 600-1000 pictures over 6-8 hours. Is this feasabile? How much battery drainage can I expect?

Handling & Autofocus:
How easy is it to take quickly lots of these pictures while hiking through rough terrain (opening of the camera app, one hand shooting, etc.)?
How reliable is the autofocus for macros of insects and plants and how reliable for flying birds?
