Ok, so I sent in both of my 5D3s and my 24-105 last Thursday, arrived at Canon NJ Friday morning. Monday I call the NJ office to see how the repairs were going and when I could expect them back since it would be great to have them in time for Thanksgiving. Fools didn't even open the box yet and it was still sitting at their warehouse since Friday morning. What's the point of placing the CPS decal on the outside of the box for express service as indicated in their instructions if my shipment falls through the cracks and gets left in their receiving bay for an entire day doing nothing? Anyway whatever, I let it slide. I figured if they fix the AF issues, what's a little delay right?
So as Tuesday rolls around, it becomes evident that I won't be receiving my gear in time for the holidays. I called them and offered to drive all the way from Long Island to pick them up in NJ on Wednesday, even though the CPS return shipping is free. I fought the worst traffic of the year and finally arrived at the NJ office. I went 100 miles in 4 hours, driving manual in bumper to bumper gridlock.
The lady returned my gear and the work order forms. "Electrical adjustments were carried out on the af assembly. Product functions were confirmed. Checked all, adjusted focus & exposure, f&b, cleaned to factory specs. Cleaned C-mos & adjusted with lens." That's it. I asked if I could have the tech notes and she said she didn't have them. "Electrical adjustments" are meaningless to me lol. I want to know which AF points were adjusted and by how much and whatever else was done. This way, I would know if the tech was on the right track and if my issue ever needs to be revisited by that tech or another tech, they would know the history of the work that was done. Surely these techs keep notes, right?
So I brave the traffic back to Long Island and was eager to run the bodies through some basic testing. I set up the FoCal target, 12EV halogen brightness, 40x focal length, tested 105mm at f/4. Center point AFMA now yields +5 wtf lol! Whatever, if all of the AF points are around +5, I'll live with it. I then tested the upper-right-most outer cross point. +11. In other words, not only is my center point a +5 now (was 0 before), there is now at least a 6 AFMA units of difference between my center point and the outer point I mentioned - more than before.
I stopped the testing right then and there, no point in continuing with other AF points or with the second body. These tests are time-consuming and I don't think I should be the one doing this after receiving a "fixed" product. This is the reason I want to see all of the tech's notes, including what was done to fix the AF and also their findings and observations during the quality check. Since this is free warranty work, do you think these guys do haphazard, non-involved work and hope the customer just lives with the issues and pray they don't come back a second time? Or did I just get a bad tech? Just trying to fathom how this could have happened. Seeing such poor results, I just don't see how the tech could have signed off on the quality check. Doing the "electrical adjustments" implies and is an admission that he found some fault with the AF. So the result is worse and he is ok with it and verifies the work to be handed back to the customer? I don't get it. Now I have to waste more time and more money returning my gear to the repair center again. Any word of advice on what/how I should phrase my repair form?
Anyway, Happy Thanksgiving to all who celebrate. In the grand scheme of things, these cameras are insignificant compared to other more important things in life and we should be constantly thankful for what we have, just a little annoyed that they half-assed the work when it didn't need to be that way.
