For the smart Mexican boy.
I have to admitt you are right regarding the option for Kinor or ARRI in order to improuve the image quality of your shooting on 16 mm. But from this point to accepting your arrogant point of view ( I quote you: "A K3 is useless for anything other than "down and dirty" documentary footage, B-Camera, Crash camera (like the suicide scene in Clockwork Orange), or something like that...") is a long distance. If you are pacient and careful enough, if you have a real artistic mind, full of imagination and gift for picturality, you could shot in a very good esthetic conditions on Frere Lumiere old Pathe camera. Please, look on youtube some footage shot with K3 (the Ian's movies on railways are a good example), excellent edited, and maybe you will less arrogant. I am not K3 advocate, and I know now very well its technical limits, but I think shooting with it is a useful school, a good and chepaer semi-professional starting in the filmmaking direction. It is very easy to show up as a lazy person, saying "bleah!! a K3 is a dirty thing" and then demanding with arrogance the latest technical achivements in oredr to justify your lacke of talent and of imagination.
