A Sinar F is great for macro because you can screw on additional sections of rail and attach additional standards, so that another length of bellows may be added. I can shoot 1:1 with my 450mm if I want, but I never have because the bellows would be a sail at such an extension.
Most people here are patient with beginner questions. At least they were when I was asking them. Better to ask and get started now.
