I think a lot of people are forgetting that speed is part of the job and really the dp and director just want to see what the lens looks like STRAIGHT AWAY. a crew only moves as fast as its camera dept. and until theres a lens on the camera, not many decisions can be made besides when you're swinging a lens and the suns going down, you don't have time to jumble with lens caps.
Therefore the lens case shouldn't be too far from the camera. If the room is tight then it should be outside in the hallway. Any further than that and you're wasting time for the dp, director and however many dollars are chipping away at the production.
Dont run but Just repeat the focal length. open the case. Both caps off. Infinity focus. Wide open aperture and briskly walk over and hand it to the ac. Element facing them or face down in their palm. They say "got it/mine/thank you" etc. they hand you the old lens. Reply with "got it/ mine / thank you / hooray!" etc take the lens back. Both caps on. (infinity, wide open, if you want, before goes in). Close case. All latches down. Yay.
every 1st will have their own preferences but this is a very efficient way of doing it. If your on a long form production and have to do this every day for the next how many weeks and months, people will lose patience very quickly. especially the stressed out dp.
