How to choose the right memory card for your camera?
The right memory card must be fast enough for your camera’s recording modes and large enough for your shooting sessions. Using a card that is too slow causes recording failures. Using a card that is too small means running out of space at critical moments.
Matching card speed to camera requirements
Check your camera manual first. Every camera lists minimum card speed requirements for each recording mode. This is the definitive reference.
For 4K video at standard bitrate (100-150 Mbps): UHS-I V30 or U3 cards are sufficient. Most affordable option for everyday 4K.
For 4K video at high bitrate (200-400 Mbps) or ALL-I: UHS-II V60 or V90 cards required. The faster write speed handles the data throughput.
For 8K video or RAW video: CFexpress Type B typically required. SD cards cannot handle the data rate.
For photography burst shooting: Faster cards clear the buffer sooner. A V90 card lets you shoot longer continuous bursts before the camera slows down.
Capacity — how much do you need?
Photos only (24MP RAW): 64GB holds roughly 1,000-1,200 RAW photos. Plenty for a day of shooting.
4K video at 150 Mbps: 64GB holds about 45 minutes. 128GB holds about 90 minutes. 256GB holds about 3 hours.
Mixed photo and video: 128GB is the practical minimum for a day. 256GB gives comfortable headroom.
Carry multiple cards. Two 128GB cards are safer than one 256GB card. If a card fails, you lose half your work instead of all of it.

Card buying tips
Buy genuine from authorized dealers. Counterfeit memory cards are extremely common online. They report fake speeds and corrupt your data. Camera Shop Egypt sells only genuine cards.
UHS-II vs UHS-I: UHS-II cards have a second row of pins and are dramatically faster (up to 300 MB/s vs 104 MB/s). Your camera must support UHS-II to benefit — UHS-II cards work in UHS-I slots but at UHS-I speeds.
Format in-camera, not on computer. Always format cards using your camera’s format function, not your computer. This ensures the correct file system and folder structure.
Replace old cards. Memory cards have a finite write lifespan. If a card starts showing errors or corrupted files, replace it immediately. Cards used heavily for 3-5 years should be retired to non-critical use.
The safest memory card strategy: buy two identical cards, use dual-slot recording for simultaneous backup, and always format in-camera before each shoot. This simple workflow prevents virtually all card-related data loss.
