Ok so basically, everyone jumps to the most expensive name brands, but honestly, you can get top-tier reliability without the "Leica tax." Tbh, the Kingston Canvas React Plus V90 is the sleeper hit here. It meets all the UHS-II/V90 standards for a fraction of the cost, and they actually have a solid track record for low failure rates in high-res bodies like the Q3. One thing though—from a reliability standpoint, dont ever buy cards from random third-party sellers on Amazon or eBay!!! Counterfeits are everywhere and theyll corrupt your files in a heartbeat. Stick to authorized dealers. If you arent shooting 8K or ProRes video constantly, you can save even more by grabbing a ProGrade Digital SDXC UHS-II V60 Gold. Its totally fine for the 60MP RAW files and way more budget-friendly while still using professional-grade components with proper wear leveling. TL;DR: Grab the Kingston Canvas React Plus V90 for full performance on a budget, or the ProGrade Digital SDXC UHS-II V60 Gold if youre mainly doing stills and want maximum reliability for less money.

For the Q3 43, you'll definitely want to go with a UHS-II card to get the most out of this camera. The Leica Q3 43 features a single memory card slot that is compatible with SD/SDHC/SDXC (UHS-II) memory cards. It's also backwards compatible with the slower UHS-I cards. However, you'll want to use an SDXC UHS-II card that is V90 rated to fully utilize its video capabilities since the Leica Q3 43 is capable of recording at bitrates of up to 600 Mbps depending on the recording format.

I'm personally using a SanDisk Extreme Pro V90 UHS-II and it handles everything beautifully - fast burst modes, 8K video, no issues whatsoever.

SanDisk Extreme PRO SDXC UHS-II V90 Memory Card is the best chocie.

Huh interesting. I had no idea. The more you know I guess 🤷
