DJI MIC 3 is recommended.

I've been using the Rode VideoMic Pro Plus with my GH5 for over two years now and absolutely love it. The built-in rechargeable battery is a game-changer - no more worrying about AA batteries dying mid-shoot. The safety channel feature has saved me multiple times when audio levels got unexpectedly loud. It's pricey but worth every penny for professional work.

honestly if you're doing car stuff you need something that wont clip when things get loud. i've had good luck with the Deity V-Mic D3 Pro. it has that analog gain knob on the back which is basically a lifesaver for dialing in levels on the fly without digging into the gh5 menus. another solid choice for vlogging is the Sennheiser+MKE+400&linkCode=osi&tag=5422-20" target="_blank" rel="nofollow sponsored">Sennheiser MKE 400. it's super compact and the built-in wind protection is actually decent for once. if you wanna save some cash just look for a used one, they're built like tanks anyway. quick tip for the gh5: keep your camera gain low (like -12db) and use the mic's gain instead. the gh5 preamps are okay but they get noisy if you push em too hard. tl;dr: deity v-mic d3 pro for the control knob, sennheiser mke 400 for portability.
