Memory card is not equal memory card. In addition to the type of card, storage, performance and quality should also match your requirements. If you are more of a quiet photographic mind in no particular hurry, just look at the space requirement. If, on the other hand, you are quick on the draw, you should bet on cards with high speeds. That will not only benefit you by taking pictures, but also by transferring images to your Mac or PC.
Basically, anyone who saves on memory saves at the wrong end. What is the best picture ideas, the highest quality lens and the most powerful camera, if the memory fails at the decisive moment? Therefore, pay attention not only to the price, but also to quality. Your photos should be worth it.
