Next time you watch a baseball game and you see a chest shot of the batter, with the plate ump and the catcher in the background, think about where that camera is located.

Several things stand out to me with these broadcast box lenses:
- constant apertures like f/1.7 over a huge zoom range like 30X, to about 350mm, only slowing down over the last 2X or so of the range

- industry-wide standard lens mounts (including a new 1.25” based format for 8K, still smaller than 4/3” format), which goes with ...

- two dominant brands—Canon and Fujinon, so that even Sony broadcast cameras are typically used with those “third party” lenses.

It’s impressive what can be done with the tiny 2/3” format for 4K and 1.25” for 8K when the cost and bulk of lenses is not a constraint!

ROFL.
Sony don't make broadcast lenses anyway. The TV industry has never thought of 'camera systems' like the stills industry.


Not a bad video, but a shame it appears to made as a student project, rather than by an experienced professional. Little or no mention of some of the factors that make this kit so expensive like the range of control of settings in camera head, number of video feeds needed back to the camera head, all of the audio functions.....
