You will appreciate the 250MB/s read speeds when offloading large files to your computer. It is a solid choice if you want to avoid bottlenecks while shooting bursts.

Frequently Asked Questions
Does the Leica Q3 actually need the most expensive V90 cards?
If you only shoot single frames or casual JPEGs, a V60 card is perfectly adequate for your needs. However, if you use the continuous shooting mode or record 8K video, the V90 card provides the necessary overhead to prevent stuttering. It is better to have the extra speed and not need it than to miss a shot because the camera is still writing to the card.
Can I use a UHS-I card in my Leica Q3?
Yes, the camera is compatible with older UHS-I cards, but the performance will be significantly restricted. You will notice a noticeable lag when reviewing images, and the camera will struggle to clear the internal buffer during rapid fire. Treat UHS-I cards as a backup option rather than your primary storage.
What happens if my SD card gets corrupted?
Data corruption is usually a result of improper card removal or a failing memory cell. Always format the card inside the Leica Q3 menu before every outing to ensure the file system is optimized for the camera. If you lose data, avoid writing anything new to the card and use professional recovery software on your computer.
How many photos can I fit on a 128GB card?
This depends heavily on whether you shoot DNG RAW files or compressed JPEGs. You can generally expect to store around 1,500 to 2,000 uncompressed DNG files on a 128GB card. Keep in mind that 8K video will eat up that space in a fraction of the time compared to still photography.
Is it better to have one large card or multiple small ones?
Carrying several smaller cards is a smart insurance policy against losing all your work at once. If a single card fails or gets lost, you have only compromised a portion of your photos. I suggest carrying at least two 128GB cards to balance storage capacity with physical safety.
