Nice video. Mine has a slight front focus of 8mm on around 50% of shots. So I take it I shouldn't do this mod? Also....you say it will correct front focus or back focus depending on which solder point you use but you don't explain how far forward it would bring it or how far back. Please explain.... Thanks.
It's trial and error, I used the farthest most solder points and the focus moved around 15mm.
As I mentioned in the video I lucked out and got it first time so I never tested any other points. However I do know it adjusts the focus to a lesser extent when you solder towards the middle of the 5 solder points. Take your best guess and be prepared to remove and re-solder.
Fixed mine with this method! If you have a steady hand and a thin soldering tip, you can just pop out the back cover, extend the focus out all the way, and get to it there.
That does not look like a very good way to calibrate anything.

@SuperMangn Very unusual, but it works. I fixed front focusing on my 50mm 1.8 lens this way.
