Calculating SD Card Capacity
To calculate the required SD card capacity, you can use the following formula:
SD card capacity (GB) = (Number of photos * File size per photo) / 1000
For example, if you plan to take 1000 photos with a file size of 5MB per photo, you would need:
SD card capacity (GB) = (1000 * 5MB) / 1000 = 5GB
However, this calculation assumes that you’ll be shooting in JPEG format and doesn’t take into account other factors, such as video recording or burst mode photography. To be safe, it’s always a good idea to add a buffer to your calculation, such as 10-20%.
SD Card Capacity for Video Recording
If you plan to use your camera for video recording, you’ll need to consider the video resolution and frame rate when calculating the required SD card capacity. Here are some general guidelines for SD card capacity for video recording:
- 1080p at 30fps: 1-2GB per minute of recording
- 1080p at 60fps: 2-4GB per minute of recording
- 4K at 30fps: 4-6GB per minute of recording
- 4K at 60fps: 8-12GB per minute of recording
For example, if you plan to record 1 hour of 4K video at 30fps, you would need:
SD card capacity (GB) = 4-6GB per minute * 60 minutes = 240-360GB
