Thank you for your time David, it's greatly appreciated. I've also questioned if those short zooms were done in post and it does seem most likely.
I need to leave some distance between the subject and the lens for some scenes involving chemical reactions and messy paint splattering however. So with this, would you recommend a certain long zoom with a diopter filter as my best choice or a long focal length macro?
I'm willing to test both out as I prep these coming weeks.
Thank you, thank you, and thank you for your invaluable help!
