Using the LEICA M8, firmware version 1.102 with the
LEICA TRI-ELMAR-M 16-18-21mm f/4 ASPH. and a LEICA UV/IR filter
About the lens
The LEICA M8 has an increased sensitivity to infrared light. This manifests itself in a slightly purple
rendering of dark or black surfaces (particularly black textiles). Using the LEICA UV/IR filter in front
of the lens effectively prevents this from occurring.
When using wide-angle lenses from 16 to 35mm with the LEICA UV/IR filter, a focal length specific
correction of the color cast towards the edge of the image is required. With 6-bit coded lenses, this is
done automatically in the camera as the lens type is transferred to the LEICA M8 as part of the
coding. However, in the case of the LEICA TRI-ELMAR-M 16-18-21mm f/4 ASPH., the lens type
transferred does not always correspond to the focal length actually set on the lens. Additional
information is therefore required. When the LEICA M8 is being operated with the Firmware version
1.10 (or higher), the focal length specific correction is possible for this lens too. To do this, the
Firmware version includes an extended menu:
1. Under the menu item „Lens detection“, select the sub-point “On + UV/IR” by pressing the SET
button. A new monitor screen appears with the title „Lens detection Tri-Elmar + UV/IR”.
Note:
Provided “On + UV/IR” has previously been set, this monitor screen appears automatically as
soon as the camera is turned on and/or the LEICA TRI-ELMAR 16-18-21mm f/4 ASPH is
attached, regardless of whether or not the monitor was previously active.
2. In the box with a red border, the three focal lengths 16, 18, and 21mm can be selected using
the direction buttons and/or the central adjusting dial and confirmed as normal with the SET
button.
Notes:
• The setting in the menu must be made every time the focal length on the lens is
changed.
• When the lens is attached, the middle focal length of 18mm is always preselected.
• This manual adjustment of the focal length in the menu is only necessary with the
LEICA TRI-ELMAR-M 16-18-21mm f/4 ASPH. The LEICA TRI-ELMAR-M 28-35-50mm
f/4 ASPH. features the necessary mechanical transfer of the set focal length to the
camera to display the appropriate bright-line frame in the viewfinder. The camera
electronics detect the setting and use it to perform focal length specific correction.
