My current camera is a Sony A7RIII, and today it suddenly seemed not recognize my 85mm, f1.4 lens, because the f stop did not register on the camera display. I tried turning the camera on and off, and also removed and re-inserted the battery, but there was no change. Thankfully the issue is with only this lens, so before I send it out for repair, I’m just wondering if anyone has had a similar experience and was able to correct the issue without paying for a repair. As always, thanks and advance for your help!
Did you clean the contacts?
Depress the lens lock button, twist the lens (just a bit will do) and return to locked (listen/feel the click) and turn it back on. The f stop will reappear. I have had this issue especially with larger/heavier lenses on my a6300.
I ran into this issue when I adapted my Sigma 150mm macro to the a6300. At the most inopportune times the link would be lost. Solved the problem by making a plate with appropriate shim that links the tripod collar to the camera base, thus stabilizing the interface with the contacts. Simple.

I wiped them with a cloth, but no luck. Is there a recommended cleaner fluid?

I just tried, but no luck unfortunately. I’ve also just noticed that the click on/off switch is not working either.
If this only happens with this lens then it seems like it must be the lens. I'd send that in for repair/warranty visit.

When I worked for Minolta and the Maxxum cameras came out, we were advised to use a pencil type "ink" eraser. The kind with the gritty eraser on one end and the brush on the other.

Seems to be a fairly common problem with point and shoot style interchangeable lens cameras. My first DSLR is so poorly designed that it won’t even meter unless the lens has a computer chip.
Cleaning with an eraser is no longer recommended. The gold on the contacts is so thin that is is easily damaged. A lens cleaning cloth MIGHT be ok but only wipe once.

Update...
I sent my lens to Precision Camera in CT and was told the cost of the repair was so high that they contacted Sony for replacement lens options. Two days later I received a call from Sony offering me a new lens with a new one year warranty for $500. I wasn’t able to get a lot of details about what was actually wrong with my lens, but Precision Camera told me several elements needed to be replaced. I do remember putting my camera bag down a bit hard one day while distracted by something else, and I’m wondering if that was just enough to damage the lens. While $500 isn’t a small amount, it’s certainly better than paying $1800 for a new lens, so I am very thankful for Sony’s program.

Too abrasive. Good for corroded battery chamber contacts and such. Either you’re misremembering the advice or the advice given is not qualified to give advice (I don’t care about his job title).
