OK, so after 3 years of hauling my broken Canon 16-35mm f/2.8 “L” II zoom lens around with me, not having the money to send it in to be repaired. I finally got inside it and found the broken wire causing the problem.
This what I talk about in being intelligent.
It took 3 yrs of trying to find the way inside without BREAKING ANYTHING & I was patience enough to do so.
I then without a schematic looker for where a wire should have been attached.
As you can see, it was not so obvious a place.
The first attempt to connect an extra wire to this spot did not work, the wire pictured would not solder down. So I replace it with a copper wire which did work & that little tiny extra inch of wire let me reconnect the wire inside the lens body to the circuit board.
After closing it up, I tested it and everything fired just right. 3:30am time for bed.
Next day I took it out to the street while selling & tested it more. Everything seems fine. Later that night I went and did some night shooting & so far everything is well & GOOD.
Since this is the lens that in 2014, I had a tripod fall over on a mountainside and break this lens literally in half, I assume either the solder job at the Factory Repair was bad or the wire was weaken but that fall & rolling down 100ft of mountain.
I have over $2000 invested in the lens both from buying it & then the repair of that breaking it in half. So it is nice to repair it myself & have it back in the photo kit!
Sorry I did not take more photos of the lens being opened & repaired, wee morning hours are great for working, but I don’t always remember to shoot a lot of “extra photos” on these repair jobs. I am more interested in getting the job done & get to sleep!
The Canon 16-35mm f/2.8 “L” is one of the sweetest landscape lens I have ever used.
