BTW, I cannot believe that there is a set of AF adjustment values for each user mode. You should have to do that only once. Make sure to not mix "Apply All" with single lens adjustments. Only one of the two can be effective; they are not accumulative and the global value is not a default value for any individual lens that you haven't explicitly adjusted yet. BTW, you may want to check out my
"AF adjustment hints", if you haven't done so already. Lots of pitfalls to avoid. My major gripe is that a camera-based adjustment only works optimally for a single distance. It is a pain to settle for this one distance and so far only a service calibration of the lens/camera combination or the use of Sigma dock with a respective lens can avoid this limitation.
In hindsight it's not as bad as I thought, but it's still a bit weird. What happens is you create your user modes, by saving the settings to those modes. Then later, when you make your lens AF adjustments, you have to recreate the mode settings and re save the user mode again, to overwrite it's contents with the new AF adjustment settings.
I agree though, I can't think of a single reason why you'd want to not have lens specific AF adjustments made available to all the modes, including the user ones. It is weird, but not unworkable.
I've done mine now, and really kicking myself that I didn't do it earlier. It also showed up the significant quality differences between lenses. My Tamron 90mm is staggeringly better than any of my other lenses, and quite coincidentally required almost no adjustment on both bodies.
Agree that it's a bit odd on a zoom lens. And the other silly thing is surely you could automate this based on live view contrast detect vs phase detect, given it's for static objects and all. Can't believe this hasn't been considered yet.
