Frequently Asked Questions
What SD Card Do I Need for Canon EOS R6 Mark II?
The Canon EOS R6 Mark II requires a SD UHS-II card with V60 (V90 recommended for burst) speed rating for reliable performance. We recommend 256GB capacity as the sweet spot balancing storage capacity with affordability. The device supports up to No official limit, though most users find 256GB sufficient for daily use. Always choose from trusted brands like SanDisk, Lexar, or Kingston to ensure consistent performance and avoid data loss.
Do I need two cards for the R6 Mark II?
It is highly recommended for professional work. Using both slots allows for instant backup, overflow (relay) recording, or separating file types (e.g., RAW to Slot 1, JPEG to Slot 2). For casual use, one card is sufficient.
Is V60 enough, or do I need V90?
For video: V60 is sufficient. For burst shooting: V90 is recommended. If you shoot both, V90 provides the best performance across all modes. V60 cards offer better value if you primarily shoot video or landscapes.
Is V60 required for Canon EOS R6 Mark II?
Yes, V60 is recommended for Canon EOS R6 Mark II. It guarantees a minimum sustained write speed of 60 MB/s, which is necessary for stable professional recording without dropped frames or errors.
What storage capacity should I get for Canon EOS R6 Mark II?
We recommend 128GB or 256GB cards. A 128GB card is good for typical use, with No official limit as the maximum supported capacity. Larger sizes are useful if you shoot frequently and want to minimize card swaps.
Can I use older or slower cards with Canon EOS R6 Mark II?
Not recommended. Cards slower than V60 (V90 recommended for burst) may cause dropped frames, corrupted files, or recording failures. Always use V60 (V90 recommended for burst) minimum for reliability.
Do I need a UHS card for Canon EOS R6 Mark II?
UHS cards are recommended for best performance with Canon EOS R6 Mark II. Non-UHS cards will work but may have slower transfer speeds. For this device, UHS-II is optimal.
Should I use more than one card with Canon EOS R6 Mark II?
For professional use or extended shooting sessions, dual cards provide redundancy and backup. Using multiple cards ensures you won't lose footage if one card fails. This is especially important for valuable recordings.
Does the brand matter for Canon EOS R6 Mark II?
Yes, trusted brands like SanDisk, Lexar, and Kingston are recommended. Quality brands have better reliability and warranty support. Avoid unknown brands, especially for demanding devices.
What happens if I use the wrong card with Canon EOS R6 Mark II?
Using cards slower than V60 (V90 recommended for burst) can cause: dropped frames during recording, corrupted files, or complete recording failure. Stick to V60 (V90 recommended for burst) minimum to avoid data loss.
How long will an SD card last with Canon EOS R6 Mark II?
Quality SD cards typically last 3-5 years with normal use. Replace your card if you experience read/write errors, corrupted files, or if it's been dropped or exposed to extreme conditions.
