Frequently Asked Questions
What size SD card do I need?
What size SD card do I need?
Capacity is measured in GB (gigabytes) and TB (terabytes). A 64GB or 128GB SDXC card suits many photographers, while 256GB, 512GB, 1TB and 2TB cards provide more space for extended shoots, continuous RAW bursts and 4K or 8K video recording. We recommend using several smaller cards rather than one large one, so if a card fails you only risk losing part of a shoot, not all of it.
What's the difference between UHS-I and UHS-II?
What's the difference between UHS-I and UHS-II?
This is the card's bus interface, which determines maximum read and write speed. UHS-II cards have a second row of pins on the back, allowing significantly faster read and write speeds. In compatible cameras this helps clear the image buffer more quickly during continuous shooting and speeds up file transfers to a compatible card reader.
What speed class do I need for video recording?
What speed class do I need for video recording?
Video Speed Class (V-rating) shows the guaranteed minimum write speed. V30 suits standard 4K recording, while V60 or V90 is recommended for high-bitrate 4K and 8K recording or professional cinema workflows to help maintain uninterrupted recording.
Do I need to format a new SD card before use?
Do I need to format a new SD card before use?
Yes. Insert the SD card into your camera and format it using the camera's menu. This optimises the card for your specific model and helps ensure reliable performance from the first shot.
What's the difference between SDHC and SDXC?
What's the difference between SDHC and SDXC?
SDHC (Secure Digital High Capacity) cards are available in capacities from 4GB to 32GB, while SDXC (Secure Digital Extended Capacity) cards range from 64GB up to 2TB. Most modern mirrorless, DSLR and medium format cameras support SDXC cards, although some older models may only be compatible with SDHC. Always check your camera's specifications before purchasing.
