1) take a look at this:

- definitely studio use, as no-one could sling that over his shoulder.
Besides the optics, the lens assembly had resolvers to report the zoom and focus positions, and lookup tables to translate that into barrel/pincushion distortion (used to modulate all three tube scans) and chromatic aberration (used to differentially change the scan size of red, green, and blue).

2) I don't know if for film via iconoscope (which could have as much light as you wanted), what the situation was.
I can imagine several possibilities: a) shading was needed the same as for studio work, or b) it was less of a problem, or c) it was just ignored.
Maybe someone here knows.
