Lastly, I have not done an exhaustive test of my lenses, but I do believe the problem varies depending on lens, but I don't necessarily believe it varies according to your hypothesis.
Yes, the hypothesis needs more data. There seems to be some lens dependency indeed. Which is strange enough in itself, actually. My hypothesis is compatible with the limited data I had. If anybody knows about a lens pair where the slower one jumps later (so to speak, meaning, doesn't have the focus shift while the faster already does), then this would be a very valuable contribution rejecting the max. aperture hypothesis. After all, it may be a false path...
Maybe, the AF assist light behaviour (single or multiple engagements) is lens dependent rather than camera dependent. Could be another important clue.
Moreover, I think that maybe the K10D struggles in low light as well. Unfortunately, I could not repeat the test for other cameras or brands. Nevertheless, I would be surprised to learn that focus for the K10D jumps in such a binary way when the light is dimmed.

Does the test come in at the latest firmware version? The old one i think is much better 1.01.
It is 1.01.00.05 (1.01). I heard that the 1.02 doesn't improve and so I didn't want to upgrade in the middle of my tests.
Originally posted by Christine Tham I am sure (from experience), I can do user errors as much as anybody else. So, please watch out for the errors I make :ugh:

Yes, and it has been subject of philosophical debates.
To make a long story short: If all humans were like you and unlike me, it can be shown we all would still live in caves. Like all other animals actually. To spread sperm (or raise children) isn't all you can do for your species, assuming a minimal degree of organization. I think that's all I say about this. But good literature about the topic exists. Thanks for your question.
