This is a must have for the slider. The variable tension knob can make your camera go from silky smooth medium speed (as fast as I would ever need) to super slow and smooth. There is no way I could ever get speeds this consistent by hand. The new version is smoother than first version (I have used both). Edelkrone builds top quality machines and has TOP NOTCH customer service. Cannot ask for more.
If you get the slide module v2 then this is not needed. Wasn’t really clear on the site. Will still use it though for manual slides!
Works well to smooth out ultra slow slides! I needed to do some slow, macro slides and this helped smooth out the movement.
The slider is smooth when travelling from both sides. However when it passes by the center, there is a very slight **** causing the momentum to slow. Its very slight but enough to feel it.
quality quality quality !!!
