All DSLR and mirrorless cameras have options to select the file type and quality. Traditionally, the options have been limited to JPEG and RAW, but HEIC is now a standard option on many cameras. You will need to look in your camera's image-quality or image-format menu options or refer to the manufacturer's website. You can also do an online search for "[Your Camera Model] HEIC," which should give you the information you need.
