Warning & Precautions:
•
To prevent fire hazards or electric shock, do not expose the adapter to rain or moisture.
•
Avoid changing the lens in dusty or dirty environment.
•
When carrying the camera with the lens attached/shooting, hold both the camera and the
lens at the same time.
•
Any dirt on the lens contact/mount adapter should be cleared with a blower blush or soft
brush. Do not touch it by hand or use any organic solvent. Any dirt/damage on the lens
contacts may interfere with the signal transmission between the lens and camera, resulting
in malfunctions.
Use of Camera Aperture Value
Setting the aperture value in camera will make the camera body to record the lenses' focal lengths,
so correct focal length can be shown in the EXIF data. Also, camera 3-axis stabilization can work
accordingly when recognition is done, with the data as follows:
•
f/6.3 - Let the extension plate stay at the current position after turning off the camera
•
f/7.0 - Press the shutter to retract the extension plate back to original position after turning
off the camera
•
f/8 – Switch the focal lengths between the highlighted aperture values (F4.0-F5.6)
For example, when a 300mm lens is used, the camera aperture should be set to F4.0 so the adapter
will recognise it as a 20/300mm focal length lens. If you wish to switch to the other value under the
same camera aperture, you will shoot another picture in F8 to initiate the switching step. Then you
may go back to F4 for shooting. At this point, the focal length recorded in EXIF should be changed
already.
If the focal length of your lenses is not found in the table above. You may set the camera aperture at
the closest focal length data, to ensure an acceptable stabilization effect.
Leica M lenses/most manual lenses are made for controlling the aperture value manually by
adjusting the aperture ring. Therefore, camera aperture value has no direct relationship with the
actual aperture that is set on the lens. Users need to adjust the aperture ring for their desired
aperture value to shoot with.
