Why such a simple thing has to be so complex? Did you have a problem with selecting just a equal M43 lens?

I'm still can't fathom the depth of idea behind setup

Umm, you seem to have completely missed what these focal reducers do. They are designed to adapt full frame or (some) APS-C lenses to smaller formats by shrinking the image circle, which has the added benefit of reducing the effective aperture of the lens. You couldn't attach an MFT lens to a focal reducer because it would make the image circle smaller than the sensor.

Well, if I understand you right, speed booster is a focal reducer, and it takes from FL and,shrinking an image circle, adds to an F-stop making lens faster.

Am I right? If I'm, than all these

1) the Light Cannon by Vizelex; 2) the Lens Turbo by Zhongyi; 3) the R.J. Focal Reducer; and 4) the Speed Booster by Metabones."

are just different brands of the same FL reducer, and there are 4 different setups. OP wants to compare different brands, which may make a sense.
