RF20-50mm f/4L IS USM PZ

I was worried the power zoom would feel gimmicky, but the adjustable speed lets me pull off smooth, cinematic moves even handheld. The f/4 constant aperture is a lifesaver for keeping exposure consistent while zooming during video.

The power zoom is smooth enough that I've stopped worrying about jerky zooms during video. Being able to adjust the zoom speed is way more useful than I expected for framing shots while filming.

The adjustable zoom speed is what sold me — I keep it slow for video and crank it up for quick framing changes. It stays parfocal-ish enough that I'm not hunting for focus after every zoom. Two months in and it basically lives on my camera.
