A Centon C100 - I'd borrowed a OM-1, and after months of saving I managed to afford the Centon and 2 lenses - my first proper camera. Fully manual with a light meter built in - lasted me for about 5 years throughout university, shooting for the Uni paper. A Fed3 - closest to a Leica I'll ever own. A Chinese camera off eBay with an API for me to write my own transfer functions, camera taking matrices etc. Best I've ever used - either the Alexa or the FT-one.
