Oh c'mon! Admit it. You don't have an inkling as to what I was talking about.
I have no idea what you're talking about with ***this*** post, though I am quite sure in your other post you were meaning to imply that a Leica and a SX-70 weren't considered great cameras in their time (or even today), which is just false.
And putting all that aside, all the talent in the world won't make you a successful photographer without some of the right gear. Your statement "The only thing necessary is TALENT, not the instrument" is false. It takes having talent and the right tools for the job. Some genres of photography are less demanding of gear, some are more demanding. Try to be a professional sports photographer without at least $3000 in gear... The spaces in which the games are played, and the requirements of the genre demand having a certain level of equipment. Try being an indoor portrait photographer who makes his or her living with it without some minimum level of lighting equipment (or specially oriented studio such that the natural light is just right). Try being a professional wildlife photographer with an SX 70. Try being a product photographer without the requisite lighting gear. Try being a commercial photographer with a point and shoot.
