The camera I use fits into your pocket, a Canon PowerShot SX 730 HS, camera literally goes wherever I go, more than a cellphone.
We are slowly getting all documentation collated, doing testing of limited weight for suitcase, making sure he has essentials, being at least 5 months away.
thank you very much for the information, I am looking forward to buying one in the near future.
Enjoy once you have purchased, I find them handy not being a professional photographer.
