The first thing I do is confirm whether my Canon camera supports Compact Flash cards. Not every Canon camera uses this format, so I check the camera manual or the official Canon specifications. This saves me from buying a card that won’t fit or work properly.
3. Choosing the Right Storage Capacity
I think about how I use my camera before choosing capacity. For casual photography, a smaller card may be enough.
