    Canon

    IFD

    None

    [2]

    Some CR2 images have a non-zero next-IFD pointer

    CASIO

    IFD

    None

    [4]

    CASIO

    IFD, at offset 6

    "QVC\0\0\0"

    Big-endian (MM)

    Relative to the beginning of the makernote

    [4]

    FUJI

    IFD, usually at offset 12

    Starts with the string "FUJI" 

    and a 4 byte pointer to the IFD

    Little-endian (II)

    Relative to the beginning of the makernote

    [1]

    Exif data uses big-endian (MM) byte order

    Minolta, KONICA MINOLTA

    IFD

    None

    [5]

    Camera settings tag is encoded in big-endian (MM) style, regardless of

    the encoding style of the Exif data

    NIKON

    IFD

    None

    [3]

    Models using this makernote include E990, D1

    NIKON

    IFD, at offset 8

    "Nikon\0" followed by two bytes of unknown meaning

    [1]

    Models using this makernote include E700, E800, E900, E900S, E910, E950

    NIKON

    IFD, usually at offset 18

    "Nikon\0" followed by 4 bytes which look like a version code 

    and a TIFF header

    From makernote TIFF header

    Relative to the start of the makernote TIFF header

    Models using this makernote include E5400, SQ, D2H, D70, D100, D200. 

    Makernote IFD of the D200 has no next-IFD pointer. (Is this a bug?)

    OLYMPUS

    IFD, at offset 8

    "OLYMP\0" followed by two bytes of unknown meaning

    [1]

    OLYMPUS

    IFD, at offset 12

    "OLYMPUS\0II" followed by two bytes of unknown meaning

    Relative to the beginning of the makernote

    Panasonic

    IFD without a next-IFD pointer at offset 12

    "Panasonic\0\0\0"

    [8]

    PENTAX

    IFD at offset 6

    "AOC\0" followed by two bytes of unknown meaning

    [11]

    SAMSUNG

    IFD

    None

    Relative to the beginning of the makernote

    Not supported by Exiv2 yet

    SIGMA, FOVEON

    IFD, at offset 10

    "SIGMA\0\0\0" or "FOVEON\0\0" followed by two bytes 

    of unknown meaning

    [7]

    SONY

    IFD without a next-IFD pointer at offset 12

    "SONY DSC \0\0\0"

    Seen in Jpeg images, e.g., from DSC-W7, DSC-R1

    SONY

    IFD

    None

    Seen in SR2 images, e.g., from DSC-R1
