Jesus, man. ONE LENS is sufficient! The pressmen had enough weight to worry about, and most (from what i've heard) would lock the focus and shoot hyperfocally, as it made it easier to deal with the g/n of flashbulbs. I'm sure many would have had a backup or maybe a second lens in the giant vulcanite box, but certainally not when they were moving around.
The notable exception i can think of may be the tele-optar some may have additionally carried for paparazzi stuff to get in closER, but in old photos you can see the pressmen weren't afraid to get close, unlike the superzoom creepers of today.
Personally, I prefer a 150 on my Speed.
*disclaimer* I may or may not know what the heck i'm talking about
