Why early studio cameras used turrets?
I'm curios, why early studio cameras used a turret of lens in stad of one lens unit?

Zoom didn’t really exist. So to change from wide to close in, you had to change lenses.
Zoomar was an early zoom lens out here. They were made not far from where I grew up. |

Early zoom lenses did not have a wide range by today's standards. This one appears to be marked 55mm to 160mm

Those were the days of directors calling to 'truck in' or 'dolly in'. Need a closer shot? Move there, physically. Or, cut away, change lens, cut back.

In early programs, there were also times when a dolly tire had a flat spot, and you would see the camera nod periodically if it was dollying on air.

Here, following time 00:30, you can see a dolly shot with a bit of a wobble.
https://www.youtube.com/watch?v=g09P...jPW7M&index=12 The Bell Telephone Hour used dolly shots extensively. |

Probably a union thing so the dolly operator would always have a job.

Then, when zoom lenses became available, the "truckin' zoom" was quickly discovered: Dolly in at the same rate you're zooming out (or the inverse) to give a radically different depth of field/background look while retaining the same image size of the primary subject. Can add quite a dramatic effect to an otherwise static scene. Requires excellent coordination of personnel for manual execution, or a trivial bit of code if you're in a motion control/automated camera scenario.

As Chip Chester says, zooming and tracking give very different effects. Zooming changes the perspective of the scene, tracking does not. Long focal length flattens perspective, wide angle exaggerates it, leading to the infamous "donkey shot". Portrait photography was often done with a somewhat long lens to avoid exaggerating long noses.
As others have said, zoom lenses simply weren't available in the early days. The very earliest camers didn't even have turrets, just a single fixed focal length lens. |

Yes, true. At 1936 Olympics the Germans had a single lens camera.
But wait a minute, the turret wasn't operated by the cameraman? |

But for film, or later, pre-made video, the cinematic special effect of zooming and dollying simultaneously would have to be done by two people, as coordination would be too difficult for one person. Also, the camera tilt and pan would very likely be locked down so that it couldn't be disturbed. [Edit: and it would be shot several times to try to get it right.] As stated above, a guaranteed smooth effect is obtained by computer motion-control of camera position and zoom.

The Bell clip looks to only have two cameras on it. Most of it was a Chapman crane floating along as part of the sweeping choreography. Directors prerogative. Cranes were so much better for any kind of moving shot as the camera was so far removed from the wheels but still could wobble at the end of the arm. Momentum in action. There is only one ground shot early on. Bell was shot at the NBC Brooklyn studios which had the space for all of this.
Bobby Ellerbee has a nice page on Brooklyn here; http://eyesofageneration.com/nice-sh...and-as-i-stud/ Here is another Bell clip that has two cranes and two pedestal cameras, one with a zoom for sure and the other with just a turret. https://www.youtube.com/watch?v=JZ2diDZf5nM

Thanks for posting that BTH clip. I see a zoom at 3:11, all the rest seem to be camera moves (?).

Wayne, I am deducing this from may years of directing and trying to figure out what the director (Clark Jones) had in the studio. The opening shot of Florence Henderson is pedestal/turret and that camera vacated to in-between the audience risers for the head-on shot of the artist. The zoom camera was down stage next to the down stage crane and not used much, nor would it have to cross the crane camera cable to shoot Florence. The other crane was backstage looking down at the orchestra and the reverse shot of the piano. All of this is classic Clark Jones style. One of the most famous entertainment directors of the day.
From personal experience behind a TK-43, I can say that a heavy camera up high on a pedestal is just not good for dolly/truck shots. And you "dolly in/out". You "truck L/R". Any bump by the wheels just amplifies up to the high center of gravity camera, just like the end of a fishing pole. And an added note. Zoom lenses have a long history in film but were not used much in the studio. They were just a quick way to change lens lengths but not for screen. Paramount used these heavily.
