Frequently Asked Questions
What SD Card Do I Need for Sony A1?
The Sony A1 takes a Dual CFexpress Type A / SD UHS-II card rated V60 (V90 for XAVC S-I) or faster. 128GB or 256GB covers most owners, and the maximum is No official limit. Buy SanDisk, Lexar, Samsung or Kingston from a reputable seller: counterfeit cards are the most common cause of lost files.
Is V60 required for Sony A1?
Yes. V60 guarantees 60 MB/s of sustained write, which keeps the Sony A1 free of dropped frames, clips that stop early, or corrupted files. Faster cards work too.
What size SD card should I get for Sony A1?
128GB covers light use; 256GB suits heavy use. Maximum capacity: No official limit.
Can I use older or slower cards with Sony A1?
Not below V60 (V90 for XAVC S-I). Slower cards cause dropped frames, clips that stop early, or corrupted files. Check the card label for the V60 (V90 for XAVC S-I) mark.
Do I need a UHS-II card for Sony A1?
No, but it helps. The Sony A1 has a UHS-II slot, so UHS-II cards write and offload faster. UHS-I cards work at UHS-I speed.
Does the brand matter for Sony A1?
Yes. SanDisk, Lexar, Samsung and Kingston cards meet their rated speeds. Buy from the brand's store or a major retailer: counterfeit cards sold under those names are common on marketplaces.
What happens if I use the wrong card with Sony A1?
A card slower than V60 (V90 for XAVC S-I) causes dropped frames, clips that stop early, or corrupted files. A card over the maximum capacity or in the wrong format may not be recognized.
How long will an SD card last in Sony A1?
Several years in normal use. Cards usually fail from wear or counterfeit flash, not age. Replace yours at the first write error, corrupted file or "card not recognized" message.
