how to hack efs canon lens (55-250 is) to being compatible with speedbooster on m4/3

Hi guys, how are you?.
I was looking for a tele lens but...to be honest...I did not want to spend a lot for this.

I choose a efs canon lens (efs 55-250is) because it was so cheap (89 €, on eglobal) and it has internal stabilizzation, and I can tell you something about....it works really good.

But to use it with speedbooster (in my case viltrox ef-m2) you need to mod the lens, nothing too difficult.

For me the quality is really good for photographer and videomaker, in the end for 89€ you can have a 400mm on m43 with a very interesting aperture (f4-5.6 became with speedbooster f2.8-4)

Watch results at the and of this video and let me know what do you think about.

Could be a good combo GH5/s + Viltrox ef-m2 + canon efs 55-250 ?

I will upload other test with this lens next week.
