How big do you usually buy a camera memory card?

A common 24-megapixel camera has a single RAW format of about 20MB-30MB. And 50 million pixels is about 50-70MB.

If shooting in RAW+JPG format, a 64G card can basically hold 1800 photos, that is, more than 24 million pixels, occupying 35MB. But if you record a video, it's not enough.

My personal suggestion is 40 million pixels. It is basic to prepare two cards with 64GB, and it is basic to prepare two cards with 128G for cameras with more than 40 million pixels.

Select the appropriate capacity:

1, depending on the type and expansion capacity: firstly, consider the memory card type and the maximum memory capacity supported by the device to avoid wrong selection; The second is to look at the expansion ability. If the memory card exceeds the expanded capacity, it is likely to be unreadable.

2. According to the actual situation: As a professional photographer, the daily workload is quite large, and it is difficult to be competent for storage work without a hundred gigabytes. Of course, if you just like photography, you can choose a relatively small capacity.

3. Supported format types: Also check the shooting modes supported by the memory card, such as RAW format or JPEG format.

4. From the perspective of comprehensive capacity, the camera memory card should meet the capacity of 100 g at the same time, the most basic one is about 128GB, and it also depends on the expansion capacity of the camera to cooperate tacitly.
