Hey guys, after five days of me and my dad tried to fix the xf 27mm f2.8 i think we figured it out the problem caused the error. Let’s directly into it. Also i’m not a native English so I will try my best to explain my idea. I think that the problem could be the aperture cable, as its being taped down roughly on the plastic piece, when the lens. Moving in and out, it’s being folded like a hinge. After like 4-5 years of using the cable inside probably got weaker and caused the error. Or even like my situation( got broken). So what i did is that i ordered another cable from china ( Aliexpress have it, just type in xf 27mm f2.8 parts ) then I transferred all the small parts like the censor, the aperture motor, the small chip ( resistor I guess ) to the new cable and put everything back in. But at the plastic piece instead of do it like Fujifilm, I used a piece of tape to wrapped around it like a collar to give it more angle of movement. Mine is work perfectly now after the fix. ( I bought it broken from another person )
