How to choose which card to store in DSLR How to choose which card to store in DSLR

1. What capacity should you choose? This is related to the pixel size of the camera, whether the video captured is 4K, and the maximum number of photos taken in a day. Generally speaking, if you take photos frequently, have a lot of videos, time-lapse photography, animals and reportage photography, it is best to choose a high-speed 128G memory card, two different ones. One of them is a spare. If you usually only go out with your family on weekends, and occasionally shoot long distances for about 5 days, then 64G memory cards, two different ones. One as a spare. If it is photography-based long-distance hiking, etc., you will need 256G or even 512G. Another important suggestion is: whether you are going out in the city or traveling to a distant place, prepare at least two memory cards! It is best to wrap the spare memory card in a plastic bag and put it in the EDC bag, camera strap, or photography bag that you must carry. (We can find the size of a photo and video in the camera manual. It can also be seen in the Explorer list display state of a win system computer or the Finder list of a Mac computer. You can also right-click on the photo or video , select properties or show introduction to see. Generally, the size of a 20-megapixel jpg photo is about: 7M-15M, the size of a 20-megapixel RAW format photo is about: 20M-25M, and the size of a 50-megapixel photo is about: 20M-25M. The size of RAW format photos is approximately: 60M, and videos are generally larger)

2. Selection of memory card speed and model: Generally speaking, top-level, new SLRs and mirrorless cameras use memory cards It may be an XQD card or a CFast2.0 card. For example, CanonEOS-1DXMarkII has two slots, one of which is CFast2.0 and the other is the previous traditional CF card slot. Nikon's D4 and D4S can use XOD cards, and Nikon D5 can choose dual CF or dual XQD cards. Nikon's Z6 and Z7 full-frame mirrorless cameras can only use XQD cards. Canon EOS5DMarkIV and Canon5DmarkIII commonly used by enthusiasts have dual card slots, namely CF card and SD card. If you want to shoot faster and more reliably, it is recommended to choose CF card as the main card. Generally, mid-range SLRs and low-end SLRs use SDHC memory cards. For example, the dual card slots of Nikon D750, CanonEOS6D, CanonEOS6DMarkII, and SONYα7RIII are all SD cards, one of which supports UHS-II. The dual card slots of SONYα7RIV support UHS-II. If you often shoot wildlife, 4K videos, and time-lapse photography, it is recommended that you choose UHS-II specifications when choosing an SD card.

3. Card reader selection: In order to transfer photos faster and more securely, do not use the SD card reader provided by the merchant when you buy the camera. Choose a better card reader. For people who shoot a lot of data, a fast card reader means more rest time. For the USB port of win system computer, the blue one is USB3.0, which has faster transmission speed. When using laptops and desktops, you can plug the mouse into the 2.0 white interface. The card reader and mobile hard drive for copying photos are best connected to the blue 3.0 interface.

4. Lightning protection: technical aspects: the first time the memory card is used, it must be formatted before it can be used! Every time the memory card is copied, it is best to format it in the camera, not on the computer! Don’t put your phone’s MicroSD card into an adapter case and use it as an SD card for the sake of cheapness or waste! The memory card will be damaged if it is dropped, dampened, or has too strong electromagnetic force. In dry environments in winter, special attention should be paid not to touch it with your fingers.
