Compression Rate/File Format - Leica M Instruction Manual

Notes:
On many lenses, the item number is engraved on the reverse side
of the depth of field scale.
The list contains lenses that were available without coding (prior to
around June 2006). Lenses introduced more recently are only
available with coding and therefore cannot be selected manually.
When using the Leica Tri-Elmar-M 16-18-21mm f/4 ASPH, the set
focal length is not transferred to the camera and thus is not
included in the EXIF data for pictures. If required, you can enter the
relevant focal length manually.
By contrast, the Leica Tri-Elmar-M 28-35-50mm f/4 ASPH features
mechanical transfer of the set focal length to the camera,
necessary to display the appropriate bright line frame in the
viewfinder. It is detected by the camera electronics and used for
focal length specific compensation. However, only one item
number - 11 625 - is listed in the menu for reasons of space. Of
course, the other two versions - 11 890 and 11 894 - can be used
and the settings made in the menu also apply to them.
COMPRESSION RATE / FILE FORMAT
The picture data is recorded either
a. Using one of two different JPEG compression rates -
, or
JPEG standard
b. In the file format, either compressed or uncompressed, or
DNG
c. Using combinations of one of the two JPEG compression rates
and the set DNG format, i.e. two files are generated per picture.
On the one hand this allows you to take account of the intended
usage and the available memory card capacity, and on the other hand
provides the security and flexibility essential for deciding on the usage
later.
