My most precious gears in the suitcase :
I can't leave home without my medium format Pentax 645N, my favourite. It is 25 years's old but still functional and incredible.
To help taking film photos even in the worst situations of mouvement and craziness I also cherish the Canon Eos 1N (from 1994) . Why ? Just because this 35mm film camera is very fast and can match with my entire collection of modern Canon lenses. The reactivity of digital with the softness and the colors of film !
Don't be afraid, for more safety I also use various and modern digital cameras such as the Canon Eos 5D Mark IV.
