Round and round and no focus

First, I am new to let.
I have an OM10 and 100-300mm lens.
There is no AF/MANUAL switch on the lens. In the camera I turn off AF and select manual focusing.
Then I turn the focus ring on the lens and just turns and turns and turns......more than 3,060 degrees.
Keep turning, keep turning!, aahhh the moon is gone.
Now how do you focus these things.
And the camera menu has about 5, still counting, manual focus choices, which do not make sense.
Do these little cameras have to be that difficult?
Better off using my cell, just Tap-N-Go.

Just read about this lens and apparently it takes a lot of turning to manually focus. Perhaps it would be good to use AF to get close to what you want to focus on then do manual focus.

It has manual assist auto focus which very effective plus focus peaking.
But trying to get that little red planet up in that sky the auto focus just couldn't catch it.
The manual focus assist in auto appears to be the only way to focus this lens.
Maybe it has a instruction manual. (Which is what we should read sometime?).

I think this stuff is getting overly teched. No wonder consumers prefer their cells.
Instant photos!

And this lens does not track well.
My D5500 tracks as fast as an F4!

Focus by wire, so there are no hard stops. If you start turning the wrong way, you never get there and have no indication that you do.

Turn on "reset lens" in the menu; this will set the lens to infinity focus when you power off/on.

Focus gets closer as you turn clockwise, further as you turn counter-clockwise. On my lens, it takes one full turn to get from infinity to 8 feet. So if you turn a lot, just go the other way.

I use a function button on my cameras to toggle manual focus; not sure about the EM-10 (I have E-M5's and E-M1's).

Zoom out at first to capture the moon, then zoom in and refocus.

I have E-M1 Mk2 with several Olympus lenses. All lenses have a narrow ring at the front; push it forward to engage AF, pull it back to go manual.

Yup, I was turning the wrong way. Will put to the test.
I have only Panasonic lenses. So I do not see the little rings in front.
