There are many memory cards on the market with terms that can sometimes be confusing. Let's check here the discussion based on the type of photo...
1. Casual photos
Usually this photography is only for hobbies and learning, not for professional photos. You can use standard SHDC memory, class 4 or class 6 is enough. For example, you can use SDHC 8GB Class 6. For a price of 50 thousand you can store thousands of photos.
2. Mediocre Videographer
For this type, it is recommended to use a memory card that has a large enough capacity because videos take up more space than photos. You can start with SDHC 32GB Class 10.
3. Action Photographer
This type of photography requires speed to store memory. It is recommended to use a memory card with a minimum speed of 95MB/s. Usually this type of photography uses a burst feature so it needs fast memory to avoid jams when shooting.
4. Photographer With Unlimited Funds
This type is usually for fun and tends to look for the most sophisticated and best items. You can have SDXC with a capacity of 512 GB or with a speed of 300MB/s. With this memory you can use it for any type of photography, from extreme videos to marathon photography for several weeks.
Again, selecting a memory card should be adjusted to your needs and budget, so it is important to know your needs first.
