Still need help with back focus adjustment for Epic

[Alexey Milokost]

Hi guys,
My back focus is off. I searched the manual and forum , but still couldn't find an in depth explanation/tutorial. I know that there are 2 screws, and the top one doesn't actually adjust, the bottom one does. With the torx screw I cannot reach the bottom one, instead it seems that I rotate only the top one. How can I get to the bottom one? The big question: Do I use the same size torx for the bottom one as for a top one or the bottom one should use a smaller diameter torx? With my Epic-M I got only 2 screws and only one of them fits the hole.
Need your help!

same size torx.....as for adjusting, there are a myriad of "right" ways to do this. I use HDMI out to my big screen and a wide lens.....if you search on youtube, you'll find videos on "HOW TO" i think doug underhall (spelling) did one a few years ago that explains this very well. on the R1. but same principle....but i set backfocus to infinity personally.....

Yes, I saw that video and clearly understand all the process, using hi-def display and so on. My question is that when I rotate the top screw I do not see any changes.
Should it be adjusted at an angle to actually move the bottom one?
How the bottom one is turned? Should I apply more pressure?

ok, i think i got it. in the field i tried to adjust but not luckily, did not have enough time and hi-res screen.
Simply rotating the screw does the job
