Was over at a friends house the other night and he asked me this question. I couldn't figure it out.
How does one get the AF points to light up to confirm focus with a manual lens?
I tried searching, but I think my query's were just too generic.

On top of that it depends on what MF lens you are talking about. 5D3 Gripped / 17-40L / Σ35 / 40 Pancake / Zeiss 50 MP / Σ85 / 100L Macro / 70-200 f2.8L II IS / 430 EX II / 580 EX II / Canon 2xIII TC / Kenko Ext.

Maybe his adapter didn't have a chip in it. Should focus confirmation work with an EF lens that is just switched to MF? Yes, it does!

Should focus confirmation work with an EF lens that is just switched to MF? Yes. Just look at the back of the lens, if you can see a little metal contact like this on the lens, it should give you confirmation. The "chip" on adapted lenses looks very similar to the normal EF lens contacts as pictured here  Fuji X-T3 // Fuji X-Pro2 (Full Spectrum) // Fuji X-H1 // Fuji X-T1

I was using back button focus and switching my AF-On and * buttons. So maybe if I disable those settings it will work? I'll give it a whirl when I get home. You have to hold whatever button it is that you AF with while you're manually focusing (half-pressed shutter button, or back button). It won't work if you're just focusing without holding the AF button. Fuji X-T3 // Fuji X-Pro2 (Full Spectrum) // Fuji X-H1 // Fuji X-T1
