Well that was fun

I decided that my Canon EF400mm needed recalibrating, seeing as I don’t think that I recalibrated it after replacing the lens mount last year, at least it was dry outside, can’t say that it was particularly warm though, but I can’t believe the amount of pollen that settled on the camera and the laptop in the hour or so that I was doing it.

The recalibration would appear to not really have been necessary, as the Micro AF adjustment just changed from +6 to +5, which in the real world is not particularly significant. I also ran few a few other test options and can report that all seems to be well.
