I've read the plastic bag idea plus sealing it with tap. My plan had been to keep it in a dry bag and in my backpack when not in use. I will need to change batteries and cards. My plan for that was to do both at the end of the day and in my vehicle. It will still be dusty but just not moving around. Just a quick open and close of the doors. Will put tape over both to help the seal. I will also have a GoPro so I'm not totally dependent on the X-T1 for photos.
Thanks to all for your posts.
