Programming of Dandelion for Olympus and Panasonic
Before you start
Prepare your camera as described as in part I
Programming of Dandelion is simple and includes three steps:
1. Activation of the program mode
2. Command input
3. Data input
Activate program mode in Dandelion. In order to do that press the lens reset button and no later
than in 2.5 seconds press and hold the preview button for 10 seconds. At the 11th second the
camera will display aperture sign "-.-". This means that Dandelion has entered the program mode.
Press the lens reset button again. Dandelion will be ready to accept the command and data. Control
dial will let you change the aperture from F4.0 to F11. Herewith each aperture corresponds to a
number (see table 1).

Corresp. number
All new Dandelions by default have a 10-second delay before activation. You can change it from 01
to 99 seconds (see F11 function). A short delay helps activate the program mode quicker. A longer
delay excludes the possibility of an accidental activation.
Make sure that you press the preview button no later than 2.5 seconds after you pressed the lens
reset button, and that you hold it continually for 10 seconds. Otherwise the program mode will not
be activated. The camera has to be prepared as described as in part I; if not, there is no guarantee
that all commands will work correctly.
Dandelion will stay in the program mode until you enter command and data. If you wish to quit the
program mode anyway, turn the camera off using Power on/off switch.
Command and Data Input
Command input is as simple as pressing the preview button on a certain aperture. After that you will
have to enter several digits (data). The data are to be entered as such, for example, the number 28
must be entered in the following way: first 2, then 8.
List of Commands And Their Formats
F4.0 + 2 digits - aperture change. The first digit corresponds to an aperture value before point.
The second digit - to an aperture value after the point. For example, to set aperture 2.8 press the
preview button successively on apertures F4.0 (command – F5.6 works with older adapters), F5.0
(the first digit is 2), F10 (the second digit is 8).
Aperture change ranges from F1.0 to F9.9. If the command and two digits are entered correctly,
there will appear aperture sign "-.-" on the display. Press the lens reset button and check the result.
Mind that if aperture is set from F1.0 to F1.9, it will influence exposure metering and reduce it.
