Ben, I know all about that. I am sort of a gear head, too. I'm a mechanical design engineer, have been an engineering manager, quality assurance manager, CNC machine programmer, and have owned a high precision CNC engineering company for about 25 years. I own and use some very high quality 4x5 gear and a 1DsIII (like you) with a bag of canons top lenses and a bunch of Zeiss as well. I'm not saying this to show off or anything like that, just to relate that we have common background. I try not to let my gear dominate my...Show more →
I understand this, but I am pretty sure there is a problem. The camera had to go in for dust cleaning anyway, so why not ask for this issue to be checked. If it is not the camera, then for sure the new lens needed adjusting. There is a good chance I caused the problem by mounting a heavy lens (500f4) on it. Or the sensor replacement might have been the cause.
I started with film in 1981. But I never mastered manual focus and few of my images were in focus so I gave up until my kids were through college and I could afford an AF system. I need it to work.
Canon always said the camera/lens was in factory spec, but then they introduced micro adjust and guess what, they all needed it. My 35L required +15 clicks. It was horrible without it and fantastic with it.
