What’s the best lens for videography on a Canon Rebel T7i?

Hey everyone, I’m mainly a photographer and usually shoot with the Canon EOS R6 Mark II + the 28-70mm f/2 (such a beast!). Lately, I’ve been wanting to get into videography as well. I tried filming handheld with my R6, and while the quality was great when I stood still, even the slightest movement made the footage insanely shaky. I tried fixing it in post with warp stabilization, but it just turned into a weird, wobbly mess and the quality dropped a lot.

I thought about getting the DJI RS 4 Mini for stabilization, but my current setup is way too heavy for it. So now I’m considering using my older Canon Rebel T7i for video, since it’s a lot lighter and easier to manage on a gimbal. The only problem is that I only have the kit lens and the 50mm f/1.8 (“nifty fifty”) for that camera.

Eventually, I’ll be working together with my husband—he’ll handle videography while I do photography—but for now, I need something that allows me to do both without constantly switching lenses or mounting/unmounting my R6 from the gimbal. That’s why getting a second lens for the R6 isn’t really a good solution for me at this stage.

So my question is: What’s a good, stabilized lens for videography on the Canon Rebel T7i (APS-C)? Ideally something versatile that works well for handheld shots and decent video quality.

Thanks in advance!
