If you're not in a rush I would wait for Photokina and see if Canon comes out with a body that tickles your fancy.

Thanks horshack. I think I have the AFMA at the best possible setting, based on multiple tests, it just isn't quite as sharp as when focusing with Live View.The DOF increments associated with each AF tune increment are pretty thin, so if you're not getting AF results that match LV then that might suggest you haven't arrived at the optimal tune value just yet. In your testing, is every AF photo consistently not as sharp as your LV at your arrived tune value, or is it that there is shot-to-shot variability at your tune value? Do you see the problem at all focal lengths on the zoom?

What is the potential risk with ML anyway? I believe I've read something about frying your sensor (!) when using Dual-ISO. Is that a big risk and if so, why?No risk. ML runs on your memory card, the moment you replace the memory card, there is no ML ... use it without fear.
My understanding is that once you install it on the 5DIII you cannot undo the boot flag. This means that if you don't like it (slow boot times, or something else), you can't "reset" your cmaera to factory performance. That is a barrier to me. I'll give it a try when I see that it is completely reversible.
I don't think CDAF's lack of predetermine directionality would matter in this case. All that is necessary is for CDAF to achieve focus as a reference point. Once a reference point is attained (and CDAF CAN indeed achieve very good focus once it's done going through all its gyrations), you save the focus group position of the lens, then all you need to do is test PDAF at a distribution of AFMA settings until you zero in on the one that most closely matches the CDAF position, and ensure that setting produces repeatable results.
I use Reikan Focal. It works and is accurate. Dot Tune seems to have a broad tolerance for accuracy.There is no broad tolerance with DotTune. The midpoint of the confirmed range is the optimal AF tune value. Those who have tried both FoCal and DotTune report to me that both arrived at the same calculated AF tune value.
I am having trouble discerning the progress of the automated dottune in Magic Lantern.
I have tried reading their website, but am a little confused if it is available.
If it is available (5DMk3), which version of Magic Lantern do i need to download.
If I use Magic Lantern to determine an amount of fine adjustment, will it move it to the cameras internal
memory area, or do I need to modify that value manually.
Essentially, I was wondering if I needed to be using Magic Lantern all of the time to be able to get the adjustment
during actual use of the camera/lense combo
Thanks for any info you can provide.
FF sensors have 2.25x more area than an APS-C sensor. That means than APS-C sensor must be 2.25x more efficient at converting light in order to even just match a FF sensor's performance let alone exceed it. That's just not possible when both chips benefit from the same technology improvements. It's only possible when comparing a much older FF sensor vs a contemporary APS-C sensor, such as the 5Dc vs D7100/K-3.
ok.. thatá what logic tells us.... so how do you explain the results?
