I find myself looking forward to the holiday of a lifetime during 2019 with a trip to America, visiting family and friends in the Western States, I'm going for several weeks. I haven't travelled by aeroplane for over 25 years - I'm reliably informed that passengers sit inside these days hahaha. In terms of flying anywhere I class myself as a 99% novice. This will be a holiday for taking snaps of people and photos of landscape and wildlife. Here's my thinking and I'm really inviting advice based on practical experience please: Kit: 5DII + battery grip and lenses or Samsung Note 8 phone cam - do I enjoy the ability to get the best out of every situation with the option of using either piece of kit or do I simply travel light with the phonecam? If 5DII kit, I'm probably going to want to take my 16-35L and 70-200L and CP filters, (leaving behind 50mm, 100-400L and all mf lenses) plus spare batteries and charger. I probably wouldn't take a flash unit.There's a growing weight issue here and a practicality in terms of what else I might need to carry. I use a padded shoulder bag which will just accomodate the camera & grip, the two lenses, filters and a couple of spare batteries but I wouldn't trust it to absorb a serious bash. File storage/transfer: I'm I'm prepared to get a new 2Tb storage device to empty my CF cards to, daily if needs be. - Flight travel luggage: I'm completely ignorant on whether to carry all my camera kit as carry on hand luggage or to consign it to hold luggage? I need to emphasise that this is a holiday for my wife and me, taking photos will be a secondary activity (the house rule is that we go somewhere because we want to and I take photos, we do not go somewhere just for me to take photos.) Data Integrity: Do I worry about airport security scanners corrupting my stored files? Am I over-thinking this? What would you do? What would you advise?
