Frequently Asked Questions

What To Prioritize When Buying an SD Card for a Digital Camera?

  • Capacity– The most important point is capacity. Make sure you have enough space to store all your data and files in it. Nobody wants to see the warning note saying “Not enough space”. It is extremely annoying, we can all agree on that.
  • Reading Speed– The second thing to look for is reading speed. If files aren’t transferring fast enough, it will be the waste of time. UHS-I devices can reach 104MB/s at maximum. As for UHS-II, reading speed reaches 312MB/s at maximum.
  • Reliable Brand– If the brand is not reliable itself, who in the right mind thinks that an SD card would work fine. Always choose between popular brands.
  • Compatibility– Everything is trash if your digital camera is not compatible with your chosen SD card slot. It can be a high-end brand and performer, but still, if it’s not compatible, there is no point in being fully feature-packed.
  • Durability- Unless you aren’t a studio photographer or videographer only, don’t forget to check if there is a waterproof, shockproof, wear-out, or temperature-proof features. The thing with these features is that you will shoot in different weather conditions, and the sun won’t always shine. You must look at how tough the card can be in these environments.  

What Type of SD Cards Can You Use in Camera?

There are 3 types of SD cards in total, and they are

  • SDXC
  • SDHC
  • SD

Deciding which type to buy is not a complicated choice.

It depends on your intention, for example, if you are a more video-oriented card seeker, it would be better to choose the SDXC card type. Also, video processing takes time as you already know. To prevent that, try choosing the fast reading speed card slots.

For additional performance, SDXC-type cards feature an exFAT file system to hold up with large-sized data. This boosts the performance of your Sony a7III camera which is at high-bitrate.

SDHC which stands for high capacity card type stores a limited data capacity of 32GB. Nowadays, when a single standard picture resolution is only 1024 pixels wide and 72 PPI for web images, it will be hard for your shots to survive, let alone handle 4K or upper-resolution requirements. 

Also, MicroSD Cards do amazing work if they are compatible with Sony a7III.

Can You Fit Any Type of SD Cards in Digital Cameras?

sd t20 RwewRN

Unfortunately, there is no universal SD card that can fit all digital camera types. At least not yet. 

For professional and advanced digital cameras, the SD card should support strong quality in comparison with those used in smart devices. 

Newer released SD card models mostly are compatible with any type of camera. That question depends more on whether your camera can handle that exact SD card. 

Can You Put the Same SD card in Different Cameras?

Yes, you absolutely can. However, there is a high chance of damage over time if you do it continuously.

UHS I cards vs. UHS II Cards

So, what’s the difference between UHS I cards and UHS II Cards? There’s only one main difference between then, and that is the read and writing speeds. UHS II cards usually tend to be faster than UHS I cards.

Final Thoughts

SD cards are must-have devices for digital cameras. Choosing the SD card that will fulfill your expected performance is ranked in the list. 

Most importantly, look for a capacity and reading/writing speed, and then other features. We don’t want to waste time waiting for the data to upload.

The durability in the difficult conditions is another feature to consider when buying an SD card even though most of them are weather-sealed.
