Helicon FB Tube Questions
Posted: 10.09.2018 17:11
Hello,
As the new owner of an FB tube, I have a few questions for the cracks.
Is it correct that the tube doesn't detect a lens change, i.e. there is no change of the set number of steps?
If the aperture is changed, the preset number of steps will not be changed either?
In the manual for "setting the step" you will find part 7:
"...For example, you found the step 100 to be optimal at f4. When you choose f8, the program will show you that the recommended step is 200..."
Shouldn't the number of steps be calculated to 50, because the depth of field doubles when fading down from f4 to f8, so I only need half of the steps for the same range of depth of field?
Thank you for answering my stupid questions.
greetings
Matthias
