yes, it is clear but I cannot imagine, that there are no vibrations in havy setups.Flash does not help subject movement
I’m afraid that they are noticeable at 50x or higher.

I've found that having a very stiff setup with multiple levels of vibration attenuation and using EFCS helps, but some residual vibration is always present. Of course the brute force solution is make everything heavy, but an analysis of things can point to solutions that don't necessarily require extremely heavy components. Popular aluminum extrusions are an example of support that has a good stiffness to weight tradeoff, using vibration absorbing materials (Sorbathain), and common-mode techniques can help.Adalbert wrote:Hello Mike,yes, it is clear but I cannot imagine, that there are no vibrations in havy setups.Flash does not help subject movement

Yes, this is a typical type solution. Going from stiff material to soft, then to stiff is like an electrical equivalent of a Low Pass Filter, this helps attenuate higher frequency vibration components. Having the camera/lens and subject holder mounted to the same stiff aluminum bar is Common-Mode which helps reduce the effects of low frequency vibration components.Adalbert wrote:Hi Mike,
My setup bases on a different idea.
The core consisting of the rail with the camera and subject-holder are mounted to the aluminium bar,
which is softly mounted/clamped to the wooden frame.
In this way the transfer of the vibrations from outside is decreased.
